“…In particular, because the IAA content decreases in the latter half of the development period of berries and abscisic acid (ABA) content rises at this time (Coombe and Hale 1973;Inaba et al 1976), these two hormones may be involved in the maturation of the grape. ABA can also promote skin colouration apparently by activating L-phenylalanine ammonia-lyase (PAL) activity (Kataoka et al 1983). Studies on the effect of ABA on sugar content have not been conclusive.…”

The influence of 5-aminolevulinic acid (ALA) on the growth, photosynthesis, and fruit quality of gibberellin-induced seedless 2-year-old ''Delaware'' grapevine was examined. The result of soil treatment (0.1-10 mg l )1 ) and foliar spray treatment (30-300 mg l )1 ) with ALA after flowering was significant growth improvement, up to 55% in the lateral shoot, and up to 38% in leaf area. Optimal doses were 1 mg l )1 soil treatment and 100 mg l )1 foliar treatment. The photosynthetic rate of plants treated with ALA increased by a significant 9.2%-22.5%. Relative to the control, based on measurements of the 5th leaf of each shoot in the ripening period, the optimum concentrations for growth and photosynthesis enhancement in grapevines were 100 mg l )1 (foliar treatment) and 1 mg l )1 (soil treatment). Total plant weight at harvest increased a significant 13% at the optimal treatment doses. In terms of fruit quality, the cluster fresh weight increased a significant 44.9%-53% and fruit colour showed a tendency to become darker in all plants treated with ALA. The°Brix value in the plant treated with 100 mg l )1 ALA was a significant 2.7% higher than that of the control. We consider that leaf area and photosynthetic rates during cultivation are important for the acquisition of photoassimilates and that these are likely to be causally associated with improvement of total dry weight and advance of fruit quality. In addition, a possibility of advancing the harvest time of grapes by ALA treatment was shown.

“…While PAL, C4H, and 4CL play pivotal roles in the biosynthesis of plant secondary compounds and the levels of these three enzymes seem to be highly regulated in response to a wide variety of developmental and environmental signals (Ragg et al 1981;Hahlbrock and Scheel, 1989;Achnine et al, 2004), no detailed reports were found concerning the changes in these enzymes during fruit development. During the development of fruits such as strawberries, grapes, apples and pears, PAL activity had two peaks, one at the early development of the young fruit and another during the ripening phase (Kataoka et al, 1983;Blankenship and Vnrath, 1987;Cheng and Breen, 1991;Viljoen and Hoysame, 1995). Hrazdina et al (1984) found that during development and maturation of de Chaunac grape berries, PAL showed two different stages of activity, and that activities of C4H and 4CL paralleled the PAL changes when the development process reached its final stages and at the beginning of maturation.…”

“…However, ethylene may play a secondary role in conjunction with other growth-regulating hormones. It has been suggested that the increase in ABA levels, which begins at veraison, may be the trigger for ripening and that the advancement or retardation of berry ripening due to exogenously applied growth-regulating compounds can be related to the levels of endogenous ABA (Coombe and Hale, 1973;Hale and Coombe, 1974;Coombe, 1976;Scienza et al, 1978;Cawthon and Morris, 1982;Kataoka et al, 1983). Coombe (1976) has suggested that the decline of ABA to a low level prior to its increase after veraison may be a part of the control process, although there is no direct evidence for this.…”

“…ABA concentration increases as berries ripen, and treatments that delay this increase delay the onset of ripening (Coombe and Hale, 1973;Scienza et al, 1978;Cawthon and Morris, 1982;Kataoka et al, 1983). The application of ABA reduced the time from flowering to ripening when applied at specific times (Hale and Coombe, 1974), again suggestive of a possible role for ABA in grape ripening.…”

Treatment of Grape Berries, a Nonclimacteric Fruit with a Synthetic Auxin, Retards Ripening and Alters the Expression of Developmentally Regulated Genes

1997

Treatment of grape (Vitis vinifera 1.) berries with the synthetic auxin-like compound benzothiazole-2-oxyacetic acid (BTOA) caused a delay in the onset of ripening of approximately 2 weeks. This was manifested as a retardation of the increases in berry weight, color, deformability, and hexose concentration. BTOA treatment also delayed by 2 weeks the increase in abscisic acid leve1 that normally accompanies ripening and altered the expression of a number of developmentally regulated genes. A putative vacuolar invertase, which is normally expressed from berry set until ripening and turned off after ripening commences, remained expressed throughout development in BTOA-treated grape berries. This elevated expression resulted in increased levels of invertase activity. In contrast, the up-regulation of four other genes normally switched on at the time of ripening was delayed in BTOA-treated fruit. These included chalcone synthase and UDP-glucose-flavonoid 3 -0 -glucosyl transferase, both of which are involved in anthocyanin synthesis, a chitinase, and a ripening-related gene of an unknown function. These observationssupport the view that auxins (perhaps in conjunction with abscisic acid) may have a role in the control of grape berry ripening by affecting the expression of genes involved in the ripening process.
