The use of plant growth regulators (PGRs) is widespread in commercial table grape vineyards. The synthetic cytokinin CPPU is a PGR that is extensively used to obtain higher quality grapes. However, the effect of CPPU on berry firmness is not clear. The current study investigated the effects of pre-anthesis applications (BBCH15 and BBCH55 stages) of CPPU on ‘Thompson Seedless’ berry firmness at harvest through a combination of cytological, morphological, and biochemical analyses. Ovaries in CPPU-treated plants presented morphological changes related to cell division and cell wall modification at the anthesis stage (BBCH65). Moreover, immunofluorescence analysis with monoclonal antibodies 2F4 and LM15 against pectin and xyloglucan demonstrated that CPPU treatment resulted in cell wall modifications at anthesis. These early changes have major repercussions regarding the hemicellulose and pectin cell wall composition of mature fruits, and are associated with increased calcium content and a higher berry firmness at harvest.

Chitosan Lactate

Chitosan is a natural biopolymer that must be dissolved in an acid solution to activate its antimicrobial and eliciting properties. Among 15 acids tested, chitosan dissolved in 1% solutions of acetic, L-ascorbic, formic, L-glutamic, hydrochloric, lactic, maleic, malic, phosphorous, and succinic acid. To control gray mold, table grape berries were immersed for 10 s in these chitosan solutions that had been adjusted to pH 5.6. The reduction in decay among single berries of several cultivars (Thompson Seedless, Autumn Seedless, and grape selection B36-55) inoculated with Botrytis cinerea at 1 × 105 conidia/ml before or after immersion in chitosan acetate or formate, followed by storage at 15°C for 10 days, was ≈70%. The acids alone at pH 5.6 did not control gray mold. Decay among clusters of two cultivars (Thompson Seedless and Crimson Seedless) inoculated before treatment was reduced ≈60% after immersion in chitosan lactate or chitosan acetate followed by storage for 60 days at 0.5°C. The viscosity of solutions was 1.9 centipoises (cp) (ascorbate) to 306.4 cp (maleicate) and the thickness of chitosan coating on berries was 4.4 μm (acetate) to 15.4 μm (ascorbate), neither of which was correlated with solution effectiveness. Chitosan acetate was the most effective treatment which effectively reduced gray mold at cold and ambient storage temperatures, decreased CO2 and O2 exchange, and did not injure the grape berries.

Early maturity is of major importance to table grape producers in Arizona and the California desert. However, table grapes in this region often experience a delayed and erratic budbreak thought to be due to a lack of chilling. The influence of three rates of hydrogen cyanamide on budbreak timing and uniformity was evaluated at a commercial vineyard near Dateland, Ariz., during the 1984-85 season. Treatments were made to three table grape cultivars over three application dates. Additional research to evaluate possible interaction between time of pruning and application of hydrogen cyanamide was conducted during 1985-86. Of the three application rates evaluated, the 5% solution provided optimal results, inducing a greater total number of buds to break for perlette and flame seedless cultivars than nontreated plots. Early application resulted in a significantly earlier but extended budbreak; later applications were more dramatic and uniform. Budbreak was accelerated by 1 to 2 weeks for perlette, and up to 2 to 3 weeks for flame seedless and Thompson seedless cultivars. Hydrogen cyanamide applications also had a positive influence on earliness of blossom and percent soluble solutes at harvest. Pruning up to 11 days before or 14 days after application of hydrogen cyanamide generally did not have a significant effect on budbreak or maturity at harvest.

Six table grape (Vitis vinifera L.) cultivars and 10 species of tree fruit were evaluated in cage tests to determine their susceptibility to colonization by the silverleaf whitefly (Bemisia argentifolii Bellows and Perring). The table grape cultivars Thompson Seedless, Perlette, Flame Seedless, Ruby Seedless, Christmas Rose, and Redglobe were all colonized. In a field nursery, with naturally occurring silverleaf whitefly populations, `Zinfandel', `Sirah', and `Chardonnay' were more heavily colonized than were `Merlot', `Thompson Seedless', or `Redglobe'. The tree crops `Kerman' pistachio (Pistacia vera L.), `Calimyrna' fig (Ficus carica L.), `Nonpareil' almond [Prunus dulcis (Mill.) D.A. Webb], and `Fuyu' persimmon (Diospyros kaki L.) were colonized in cage tests. Silverleaf whitefly failed to establish colonies on caged `O'Henry' peach [Prunus persica (L.) Batsch.], `Fantasia' nectarine [P. persica (L.) Batsch. var. nectarina (Ait.f.) Maxim.], `Casselman' plum (P. salicina Lindl.), `Tilton' apricot (P. armeniaca L.), `Granny Smith' apple (Malus domestica Borkh.), and `Hayward' kiwifruit [Actinidia delicoisa (A. Chevalier) C.F. Liang et A.R. Ferguson].

And Control

The volatile-producing fungus Muscodoralbus is being developed as a biological fumigant for postharvest use, as it can kill storage pathogens and control fungal decay in various commodities. A wettable pad or sachet system made of teabag paper containing desiccated rye grain culture of M. albus was designed for the biofumigation of individual fruit containers. The fungus is reactivated before use by a brief immersion of the pad in water. This research was conducted to determine the potential of the pad system for controlling decay of table grapes in commercial cartons. Individual pads containing 24 or 86 g of grain culture (to achieve a 1:10 ratio of fumigant to box volume or a 1:100 ratio of fumigant to fruit weight, respectively) were added to Styrofoam cartons containing 8.6 kg of freshly harvested `Thompson Seedless' (TS) or `Ruby Seedless' (RS) grapes, which were then placed in cold storage at –1 to 0 °C. Control cartons exposed to SO2 were placed in a separate storage room and SO2 fumigation was performed once for TS and weekly for RS. After 8 to 9 weeks, the grapes were taken out of storage and rated for decay. In the experiment with TS, the 24-g and 86-g pads provided significant control of gray mold rot when compared to untreated cartons and were not statistically different from cartons exposed to a single SO2 fumigation. In the experiment with RS, only the 86-g pads provided significant decay control. Measurements of the three most abundant volatile compounds in empty cartons containing 10 g of the biofumigant revealed that partial coverage of holes mimicking obstruction by packed fruit achieved levels of isobutyl alcohol, 2-methyl-1-butanol, and isobutyric acid of 0.7, 1.6, and 11.2 ppb, respectively.
