“…Treatment with GAs, CKs or melatonin were reported to induce extrinsic parthenocarpic fruits in several European and Asian pear cultivars [4,22,23,39]. Moreover, GA treatments were also reported to increase fruit size in European and Asian pears [4,14,23,42]. We observed that GA and CK treatments affected the phytohormone and PA profiles and metabolism and that the effects varied according to the hormone tested.…”

“…Once the fruit is initiated, fruit growth is due primarily to cell division and then continues, mostly by cell expansion, until the fruit reaches its final size [9]. Cell division and cell elongation activity are coordinated by a delicate balance between GAs and auxins during fruit development even if other phytohormones such as CKs and brassinosteroids may be involved [7,[12][13][14]. Abscisic acid has also been associated with the expansion phase in some species [7].…”

Hormonal Regulation of Early Fruit Development in European Pear (Pyrus communis cv. ‘Conference’)

et al. 2019

European pear requires inter-cultivar cross-pollination by insects to develop fertilized fruits. However, some European pear cultivars such as ‘Conference’ naturally produce parthenocarpic seedless fruits. To better understand the hormonal regulation of fruit set and early fruit development in this European pear cultivar, the phytohormone and polyamine profiles in ‘Conference’ flowers and fruits resulting from both fertilization and parthenocarpic processes were analyzed. The expression of genes involved in phytohormone metabolism and signaling were also investigated. Phytohormone profiles differed more at flower stage 3 days after treatment than in 15 day- and 30-day-old fruits in response to fertilization and parthenocarpy. An increase in auxins, abscisic acid, ethylene precursor, and spermine, and a decrease in putrescine were recorded in the fertilized flowers as compared to the parthenocarpic flowers. Fertilization also upregulated genes involved in gibberellin synthesis and down-regulated genes involved in gibberellin catabolism although the total gibberellin content was not modified. Moreover, exogenous gibberellin (GA3, GA4/7) and cytokinin (6BA) applications did not increase parthenocarpic induction in ‘Conference’ as observed in other European and Asian pear cultivars. We hypothesize that the intrinsic parthenocarpy of ‘Conference’ could be related to a high gibberellin level in the flowers explaining why exogenous gibberellin application did not increase parthenocarpy as observed in other pear cultivars and species.

“…It was likely that GA did not turn reliably on the inhibition of bulbing, in its place attracting the outbreak of a "bulbing reserve substance" [57,58]. GA3 application could increase shoot weight in carrot [59], seed yield in lettuce [60], and fruit weight in pear [61] and plum [62]. Earlier reports have revealed that the application of GA3 increased bulb weight in onion under deficit irrigation [63].…”

The photoperiod marks a varied set of behaviors in plants, including bulbing. Bulbing is controlled by inner signals, which can be stimulated or subdued by the ecological environment. It had been broadly stated that phytohormones control the plant development, and they are considered to play a significant part in the bulb formation. The past decade has witnessed significant progress in understanding and advancement about the photoperiodic initiation of bulbing in plants. A noticeable query is to what degree the mechanisms discovered in bulb crops are also shared by other species and what other qualities are also dependent on photoperiod. The FLOWERING LOCUS T (FT) protein has a role in flowering; however, the FT genes were afterward reported to play further functions in other biological developments (e.g., bulbing). This is predominantly applicable in photoperiodic regulation, where the FT genes seem to have experienced significant development at the practical level and play a novel part in the switch of bulb formation in Alliums. The neofunctionalization of FT homologs in the photoperiodic environments detects these proteins as a new class of primary signaling mechanisms that control the growth and organogenesis in these agronomic-related species. In the present review, we report the underlying mechanisms regulating the photoperiodic-mediated bulb enlargement in Allium species. Therefore, the present review aims to systematically review the published literature on the bulbing mechanism of Allium crops in response to photoperiod. We also provide evidence showing that the bulbing transitions are controlled by phytohormones signaling and FT-like paralogues that respond to independent environmental cues (photoperiod), and we also show that an autorelay mechanism involving FT modulates the expression of the bulbing-control gene. Although a large number of studies have been conducted, several limitations and research gaps have been identified that need to be addressed in future studies.

“…In general, the slow decomposition process of compost contributes to the slow release of nutrients and consequently prevents excessive growth of vegetative part, which in turn, increases the storage root yield (Leng, 1982). Gibberellin was reported to increase stem elongation and flower formation of Arabidopsis thaliana (Xu et al, 1997), seed germination of Tithonia rotundifolia (Patel and Mankad, 2014) and fruit size of Pyrus pyrifolia (Li et al, 2015). However, gibberellin is also one of the factors that inhibits or delays potato tuber initiation (Davies, 2009), which consequently reduces the sink strength of tuber to attract assimilate and causes a reduction in the allocation and accumulation of dry mass in tubers (Booth and Lovell, 1972).…”

This experiment was conducted to investigate the effects of various treatment combinations consisting of oil palm's empty fruit bunch (EFB) compost and hexaconazole (HEX) on dry mass production, partitioning and nutrient concentrations and contents of sweet potato var. VitAto. The treatments consisted of the recommended inorganic fertilizer for VitAto cultivation (control), solely EFB compost and the combination of treatments consisting of EFB compost with 10 or 30 ppm HEX, using a randomized complete block design (RCBD) replicated four times on sandy soil. The destructive biomass analysis was carried out at 30, 55, 77 and 99 days after planting, which corresponded to the following growth stages, storage root initiation, early and middle bulking and maturity, respectively. The final biomass harvest (99 days after planting) was used for N, P and K nutrient analysis. The greatest response was observed using EFB compost plus 30 ppm HEX treatment, which significantly increased storage root dry mass production, storage root mass ratio, root to shoot ratio, plant total K content, storage root K concentration and content by 16.9%, 15.2%, 58.8%, 75.5%, 69.4% and 106.9% at the maturity stage, respectively. The results showed that the control treatment favored the growth of leaf and stem, while the EFB compost with 30 ppm HEX treatment favored the growth of storage root. The EFB treatment was able to supply high K nutrient to the plant. Both K and HEX were able to increase the assimilate translocation to storage root and consequently increased the storage root dry mass production. Based on the finding of this study, it is proposed that the EFB compost with 30 ppm HEX combination treatment could be used by farmers as alternative inputs to the inorganic fertilizer application in VitAto cultivation on sandy soil.
