“…It may be hypothesized that the berries of different positions may not equally access the assimilate pool. The berries from the proximal part of clusters might have a higher priority for receiving assimilate supply, as indicated in banana (Jullien et al 2001a(Jullien et al , 2001b. Overall, the potential roles in berry weight variation of seed number, berry position within a cluster, and within-cluster assimilate supply should be investigated jointly in both seeded and seedless cultivars in order to better explain this variability.…”

Berry fresh weight and composition are under the control of complex interactions among genotype, environmental factors, and viticulture practice, which all affect not only the mean value but also the ranges of variation in berry traits. Both mean values and variation range in berry composition play a role in berry quality and, subsequently, wine typicity. This review examines recent ecophysiological, genetic, and molecular knowledge to provide better understanding of the mechanisms that influence variability in berry weight and composition. We specifically reviewed the variation range in berry weight and composition (including sugars, organic acids, and anthocyanins) among Vitis genotypes, the environmental and viticulture practices that cause variability for a given cultivar, the genetic clues underlying the genotypic variation, and the putative genes controlling berry weight and composition. Despite numerous studies comparing differences in the mean value of a berry trait among different environment conditions and viticulture practices, very few studies have explored the level of variation in response to those factors. Present genetic and molecular studies are mainly focused on identifying genes involved in the control of berry weight and composition, with few considerations of environmental factors that affect their expression. In the future, more effort should be directed toward integration of genetic and molecular work with ecophysiological approaches in an effort to gain novel insights into the cause of variability in grape fresh weight and composition.

“…The utilization of cultivars with many female flowers, such as cucumbers with several pistillate flowers per node (multi-pistillate type) or gynoecious and parthenocarpic fruit, increases the rate at which cucumbers can be harvested within a short period (Denna, 1973;Fujieda et al, 1982; vegetative organs (Marcelis, 1992;Schapendonk and Brouwer, 1984) due to changes in sugar metabolism related to variations in fruit load (Boonkorkaew et al, 2011). The distribution of photoassimilates can be attributed to differences in the plant hormone concentrations in fruits (Bangerth, 1989(Bangerth, , 2000Bangerth et al, 2000;Bertin, 1995;Schapendonk and Brouwer, 1984), sink sizes (i.e., the number of cells per fruit) (Bertin et al, 2002;Jullien et al, 2001), or the ontogenetic order of fruit (Egli and Bruening, 2002;Marcelis, 1996). Ganeshaiah and Shaanker (1994) suggest that the autocatalytic or feedback regulation of photoassimilate flow to developing sinks also plays a role in their distribution.…”

It has been reported that parthenocarpic cucumbers with many female flowers and heavy fruit load often show fruit abortion and reduced fruit yield. To achieve the stable fruit production, it is necessary to elucidate the mechanism involved in fruit abortion in cucumbers via fruit load and endogenous plant hormones. In Exp. 1, the effects of exogenous plant growth regulators (PGRs) on yield and fruit growth were examined in a gynoecious, parthenocarpic cucumber (Cucumis sativus L.). Four types of PGR [indole-3-acetic acid (IAA), 2,3,5-triiodobenzoic acid (TIBA), benzyl adenine (BA), and gibberellic acid (GA 3 )], which have been shown to enhance fruit growth in non-parthenocarpic cucumbers, were applied using lanolin paste to the peduncles at each node (6-25) of cucumber plants at anthesis. TIBA and BA applications significantly decreased the rate of fruit abortion, thereby increasing yield. IAA and GA 3 treatments increased the rate of fruit abortion at the middle and upper nodes, thereby reducing fruit yield. In Exp. 2, to clarify whether PGRs affected the concentrations of endogenous plant hormones, and whether IAA of high concentration increased fruit abortion under low-fruit-load conditions, we applied these PGRs (two concentrations of IAA, BA, and TIBA) to cucumber plants bearing only one fruit at node 11 or 12. No fruit abortion occurred following any PGR or control treatment, although both IAA and BA treatments inhibited fruit growth. BA application increased the production of cytokinins (Z, ZR, iP, and iPR) to a level similar to that after TIBA application one day after anthesis. However, compared with the response to TIBA treatment, after BA treatment, the peak in endogenous cytokinin production occurred at an earlier stage of fruit development. Additionally, both IAA and TIBA treatments increased endogenous IAA and cytokinin concentrations in fruit. These results suggest that exogenous PGRs affect the overall concentration of PGRs, as well as that of other endogenous plant hormones. However, PGRs may not be associated with fruit abortion when the fruit load is low. In conclusion, fruit load may have a greater influence on fruit abortion than that of PGRs.

“…Means followed by the same letter do not differ significantly from each other according to Tukey's test (P≤0.05). Jullien et al (2001b) reported that the maximum diameter reached by a banana is directly related to the number of cells within the radius of the fruit, which in turn is dependent on cell division rates and the duration of cell division phase. This is consistent with the fact that the endogenous level of cytokinin is directly correlated with fruit growth and especially involved in the stimulation of cell division (Kumar et al, 2014).…”

“…Large quantities of photosynthates are moved from the source to the sink, i.e., from the leaves to the developing bunches (Mulagund et al, 2015), and the competition for assimilates between fruits determines their size and quality (Jullien et al, 2001b). Thus, strategies to standardize fruit size are of great interest because fruit mass and size (length and diameter) are important commercial criteria for marketing bananas for export.…”

of kinetin plus 200 mg L -1 of gibberellic acid, all of which were applied from the fourth to the last hand of the bunch. The bunch formation period influenced the filling time, the mass of the bunch and the stalk, the number and the mass of the hands, the number of fruits per hand, fruit size, and the position of the fruit in the bunch as well as the time postharvest shelf life, mass loss, peel color, pH, the soluble solids content and the titratable acidity of the pulp. As applied, the cytokinin and gibberellin did not influence the yield or fruit size, but bunch position had a strong influence on the size and number of fruits per hand.
