Fruit development, from its early stages, is the result of a complex network of interacting processes, on different scales. These include cell division, cell expansion but also nutrient transport from the plant, and exchanges with the environment. In the presence of nutrient limitation, in particular, the plant reacts as a whole, by modifying its architecture, metabolism, and reproductive strat...

Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

quality are influenced by many factors, including climatic conditions and production practices. In subtropical climates, the temperature usually falls below 70°F for several months during winter. This period of cool temperatures causes growth to cease and citrus trees to become dormant for about three months. The cool temperatures during this dormant period promote floral induction. When warm s...

The effects of partial root-zone drying (PRD) on tomato fruit growth and proteome in the pericarp of cultivar Ailsa Craig were investigated. The PRD treatment was 70% of water applied to fully irrigated (FI) plants. PRD reduced the fruit number and slightly increased the fruit diameter, whereas the total fruit fresh weight (FW) and dry weight (DW) per plant did not change. Although the growth r...

Salinity is an important factor in reduced cucumber yield and quality. Grafting on the resistant rootstock could keep growth near to optimum condition. The aim of the present research is to investigate the characteristics of different rootstocks on physiology and fruit characteristics of cucumber. Treatments were rootstocks [Rn: Nongrafted (Cucumis sativus v. DAVOSII), Rt: Tanbal (Cucurbita max...

Several years ago we started a broad research project dealing with the relation between the level of endogenous growth substances and the development of avocado fruit. In the course of the study, we attempted to grow cultures of avocado fruit tissue and to determine their response to the addition of growth substance. It was hoped that in this way we might learn something about the special natur...

this study was carried out on olive trees cv. amygdalifolia, to investigate the effect of spraying potassium nitrate, kno3, and zinc sulfate, znso4, on the fruit weight, dimension and volume. the plants were sprayed with 0, 0.5, 1.0 and 1.5% kno3 and 0, 0.25, 0.50 and 0.75% znso4 and their combinations in august about halfway through the fruit growth period. the highest fruit weight was observe...

Fruit growth depends on highly coordinated hormonal activities. The phytohormone gibberellin (GA) promotes growth by triggering degradation of the growth-repressing DELLA proteins; however, the extent to which such proteins contribute to GA-mediated fruit development remains to be clarified. Three new plum genes encoding DELLA proteins, PslGAI, PslRGL and PslRGA were isolated and functionally c...

Due to post-harvest losses more than 30% of harvested fruits will not reach the consumers' plate. Fungal pathogens play a key role in those losses, as they cause most of the fruit rots and the customer complaints. Many of the fungal pathogens are already present in the unripe fruit but remain quiescent during fruit growth until a particular phase of fruit ripening and senescence. The pathogens ...
