My How to Grow Juicy Tasty Tomatoes Review

Highly Recommended

I've really worked on the chapters in this book and can only say that if you put in the time you will never revert back to your old methods.

Overall my first impression of this book is good. I think it was sincerely written and looks to be very helpful.

Mass and energy balances of tomato crops 541 Carbon

Gross photosynthesis has been integrated at canopy scale in different ways. The simplest approach is to multiply the unit leaf activity by the leaf area index or by the projected leaf area ('big leaf' approach). Other models take the transmission of light in the canopy into account using an exponential law of extinc-tion.15 When the leaf light response curve is a rectangular hyperbola, analytical integration at canopy scale is possible (e.g. in Jones et al.16 for tomato crops). More sophisticated models are based on a detailed description of light distribution and absorption in canopies (see later). The respiratory efflux of CO2 is significant on a daily basis, it can represent a quarter to a half of the gross photosynthesis of a developed greenhouse tomato crop.6,9 Respiration of plants has functionally been divided in two components maintenance and growth respiration. Maintenance respiration corresponds to the energy needed to maintain the ionic gradients across biological membranes...

Types of tomato production

Finally, protected cultivation facilitates the control of pests and diseases. The use of pesticides can be reduced or suppressed thanks to biological control. For greenhouse tomato crops, the natural enemies of the most damaging pests have been identified. The development of some diseases such as grey mould (Botrytis cinerea) can be avoided with proper control of humidity and temperature, thereby limiting condensation on the foliage. climate conditions. The required nutrients can be provided either in one run before plantation or several times during crop growth. If necessary, water (possibly together with nutrients) is supplied by irrigation. Plasticulture systems equipped with drip irrigation allow the greatest control of water and nutrient availability a plastic cover spread out on the soil keeps rainfall off and limits soil evaporation. There are, of course, a large number of intermediate cultivation systems between the most sophisticated glasshouse and the most basic field...

Processed tomatoproducts

The tomato is now the most important vegetable product used in the making of industrial preserves. The 'traditional' tomato-growing nations are the USA, Italy, Greece, Spain, Portugal and France, to which have gradually been added Turkey, the countries of north Africa, Israel, Canada, Mexico, Chile and Brazil and, more recently, China, the southern republics of the former USSR, Australia, Thailand, India and South Africa. Table 4.1 shows the production data for the most recent production campaigns, from which it can be seen that, although this is an industry which produces products of relatively low added value, the USA and the EU alone process 70 of the world's entire tomato production.

Interactions with pests and diseases

Few simulation models of pests and diseases are available although their effects are of major importance in tomato cropping systems, in relation with environmental and health concerns. Seghi et al.77 reviewed some empirical models that forecast diseases from climatic data in processing tomato crops. In the 1970s, the

Areas of application plant protection

The epidemiological models presented earlier in this chapter were explicitly designed to build disease-warning systems. For example, TOM-CAST has been implemented in eastern North America in networks grouping tomato growers, the processing industry, extension services and universities. Weather sensing can be automatic or manual, data are centralised and disease severity values or advice of fungicide spray are disseminated to growers by phone or fax.78 For pest control, the model designed by van Roermund et al.82 can be used to evaluate strategies of parasitoid release for biological control under various climate conditions.

Current and future developments in modelling

From this overview of the various processes of tomato production that have been modelled, it appears that a large range of methods have been mobilised to design research or engineering models. In the fields of carbon and, to a lesser extent, water and nutrient uptake, mechanistic approaches have often been preferred. Much effort has been dedicated to the formation of yield, mostly based on the space and time integration of net photosynthesis. Practical outputs of this research can be found in the controls of greenhouse climate, of irrigation and fertilisation, and of crop management. Yet, before models could be used for designing strategies or producing decisions, they often had to be simplified.

Fungi RootNematode Interactions

Nematophagous fungi can infect, kill, and digest living nematodes. Most of these fungi can also live saprophytically and some even have mycoparasitic abilities. Since most plant-parasitic nematodes attack plant roots, the rhizosphere biology of nematophagous fungi is important from a biological control point of view. We previously described that nematophagous fungi were more abundant in the rhizosphere than in bulk soil (Persmark and Jansson 1997). In recent investigations we studied the colonization of internal cells of plant roots (Bordallo et al. 2002 Lopez-Llorca et al. 2002a). In these experiments we used axenic barley and tomato plants grown in vermiculite and inoculated with the nematode-trapping fungus A. oligospora or the egg-parasite P. chlamydosporia. Roots were sequentially sampled, cryo-sectioned, and observed under light- or cryo-scanning electron microscopes. Both fungi grew inter- and intra-cellularly, formed appressoria when penetrating plant cell walls of epidermis...

Methods for reducing spoilage in fruits

Most of the molecular biology and biotechnology studies have been performed in tomato, a model system that has been extensively studied at the physiological and biochemical levels. The earliest reports describing the biotechnological control of ethylene production in fruits and its effect on ripening were described by Hamilton et al. (1990) and Oeller et al. (1991). Oeller et al. (1991) produced transgenic tomato plants bearing inverted copies of a ripening-induced ACC synthase gene (LE-ACC2), a method known as 'antisense gene inactivation'. Some of the transgenic lines exhibited a strong reduction of LE-ACC2 gene activity leading to almost complete inhibition of endogenous ethylene production in the fruits. Antisense transgenic lines failed to ripen although they developed an orange colour when harvested and kept on air or left on the plant for up to 150 days after pollination compared to control plants that fully ripen 60 days after pollination and deteriorate soon after. The...

Plant Genetic Engineer

A plant genetic engineer must be familiar with the characteristics that distinguish plants from other types of organisms. Unlike animal cells, plant cells have tough cell walls, which must be penetrated to reach the DNA. Also, some genetic material resides in the organelles called plastids, the largest of which is the chloroplast. The engineer must also be able to regenerate an altered plant cell into a plant, test that plant in a greenhouse, and, finally, see how well it flourishes in a field environment. For example, tomato plants can be given a gene from A. thaliana that enables them to grow in very salty water. Developers of such a crop must analyze how the plant that can now grow in brackish or salty water will affect other types of plants that normally grow in that environment. Thus, in addition to understanding genetics, molecular biology, and biochemistry, a plant genetic engineer working on an agricultural variant must also have expertise in plant development and

Transgenesis and Cloning

When you introduce a transgene into an organism, you insert into the genome a foreign gene, be it from the same species or from a different one. Owing to the virtual universality of the coding properties of DNA, huge evolutionary distances can be bridged in transgenesis - the example of a fish gene inserted into tomato plants for cold hardiness achieved notoriety. In order to be of any use in a multicellular organism, the transgene must be inserted into germline DNA, so that it can be propagated in subsequent generations. Other applications where genes are inserted into somatic cells (cells that are not involved in reproduction of the organism), for example for gene therapy, were considered in Chapter 16.

Methods for reducing spoilage in vegetables

Ethylene is intimately linked to senescence and its role as a senescence inducer has been firmly established (Buchanan-Wollaston, 1997). Therefore, in addition to the delayed fruit senescence observed in low-ethylene producing fruits, tomato plants with low ethylene synthesis in leaves also showed delayed leaf senescence symptoms (John et al., 1995). A similar delay in leaf senescence was also observed in ethylene-insensitive Arabidopsis plants that had been mutagenised to disrupt ethylene perception by the cellular receptors (Grbic and Bleecker, 1995).

Physiological and Biochemical Alterations of the Host

Systemic-induced resistance (SIR) is typically the sustained induction of resistance or tolerance to disease in plants by previously inoculating with a pathogen, exposing to an environmental influence or treating with a chemical, which may or may not have antimicrobial activity (Handelsman and Stabb 1996 Kuc 1995). Researchers have suggested that AMF-inoculated plants may employ SIR as a mechanism of biocontrol (Benhamou et al. 1994 Brendan et al. 1996 Trotta et al. 1996). The SIR phenomenon in mycorrhizal plants is demonstrated as localized and systemic resistance to the pathogen (Cordier et al. 1998). An increase in the lignin deposition in plant cell walls following AMF colonization can restrict the spread of pathogens (Dehne and Schonbeck 1979). Using a split root system, Cordier et al. (1998) demonstrated that G. mosseae protected tomato plants against P. parasitica by reducing pathogen development and spread by increasing cell wall appositions containing callose close to the...

Fungi As Plant Growth Promoter 21 Pgpf

Isolates of Trichoderma harzianum and T. koningii have been shown to enhance seedling emergence in tomato with increased shoot and root dry weights when compared to nontreated control plants (Table 1) (Windham et al. 1986). These species also gave rise to increased shoot and root dry weights in tobacco (Table 1) (Windham et al. 1986). Isolates of T. viride have been reported to increase tomato plant height (Windham et al. 1986). Chang et al. (1986) have shown that isolates of T. harziamum enhanced seedling emergence in chilli pepper and promoted growth of tomato, chilli pepper,

Host Nutritional Effects

Collectively benefit host plants by creating favorable conditions for the proliferation of microflora antagonistic to pathogens such as Phytophthora and Pythium spp. as shown for eucalyptus seedlings by Malajczuk and McComb (1979). Unfavorable conditions induced by AMF colonization resulted in qualitative changes in the mycorrhizosphere that prevented P. cinnamoni sporangial induction in tomato plants (Meyer and Linderman 1986). Proliferation of G. mosseae inside grapevine roots was associated with a significant reduction in replant disease-causing fluorescent pseudomonad inoculum in soil (Waschkies et al. 1994). Promoting AMF diversity that will ensure that at least a component of the AMF community may be active against pathogens can further enhance the benefits of this mechanism.

Introduction the importance of modelling to quality

In this review, a fairly broad definition of quality in tomato production has been adopted, including the fruit sensory properties (appearance and taste), its nutritional and health value (presence of valuable nutrients, absence of chemicals or toxins) and the environmental impact of the cropping system. Many of the physical and biological processes involved in tomato production have been formalised in different ways in order to carry out simulations, make predictions or optimise their management,3 but much still remains to be done in the simulation and management of quality. In fact, effort in modelling has been proportional to the ability to control the cultivation system, that is, greater for greenhouse than for field production. In greenhouse production, modelling has focused on yield prediction, optimisation of climate and fertigation (the application of fertilizer through an irrigation system) control and evaluation of strategies of crop management. In field production, it has...

Antisense RNA

This technique was first used commercially in 1988 for the Flavr-Savr tomato. The gene chosen for inactivation was polygalacturonase (PG), whose enzyme unlinks pectins in the plant cell wall, thereby softening it. The intent was to increase the time the fruit could be left to ripen without softening, thus increasing flavor of commercial tomatoes. The Calgene company created a transgenic tomato plant expressing the antisense RNA for PG mRNA, and reduced PG production by up to 90 percent. Although the tomato was not a commercial success, it demonstrated the potential for this strategy.

Yield formation

Different approaches of modelling biomass production have been developed for different crop species including tomato. In the 'photosynthesis-driven' models, integration of net photosynthesis and conversion of the resulting photoassimilates into biomass are used to compute the accumulation of dry matter. Challa and Bakker47 estimated the potential production of greenhouse crops in various regions of the world using this approach. It is also the first step in most of the tomato crop models.16,17,48 Bertin and Heuvelink13 compared the dry matter production estimated by the models of Jones et al.16 and Heuvelink.17 In the RUE approach, the production of biomass is considered to be a sequence of energy conversions from the incident radiation to the energy content of biomass. Interception of radiation is linked to the leaf area index by a saturationtype curve the coefficient of conversion of intercepted light into biomass is higher for C4 (e.g. maize) than for C3 (e.g. tomato) species and...

Varietal Differences

Water, salt, and low-temperature or high-temperature stresses. The response to stress by plants is often reflected in changes in the edible portion of the tissue (eg, tomato plants resistant to low-temperature stress tend to produce fruit resistant to low temperatures during storage). Varietal differences have also been noted in the nutritional composition of crops at harvest and in the ability of a crop to maintain marketable quality during handling, shipping, and storage.

Virus resistance

Viral resistance was the first successful example of plant disease resistance obtained by biotechnological means. To date, most of the available examples used genes from the pathogens in order to confer resistance in what is known as 'pathogen-derived resistance' (PDR). Transgenic tobacco plants resistant to the tobacco mosaic virus (TMV) were obtained by overexpression of the viral coat protein gene in what was named coat-protein-mediated resistance (CPMR) (Abel et al., 1986). Subsequently, transgenic tomato plants containing a similar genetic construct proved to be highly resistant to TMV in field trials (Shah et al., 1995). Since this pioneering work, many plants have been successfully modified Perhaps the most successful examples of commercialisation of virus-resistant plants are squash, zucchini and papaya. Squash and zucchini are highly susceptible to a series of viruses that can cause devastating effects in the crop's yield such as the zucchini yellow mosaic virus (ZYMV),...
