Certain varieties of many species of plants develop their fruits parthenocarpically or without fertilization. The apple and pear occasionally produce parthenocarpic fruits but generally under special nutritive conditions (10). In some varieties of grapes, figs, bananas, and oranges, parthenocarpy is of great economic importance (4, 14). Because of this naturally occurring phenomenon, attention ...

Fruit set of plants largely depends on the biosynthesis and crosstalk of phytohormones. To date the role of cytokinins (CKs) in the fruit development is less understood. Here, we showed that parthenocarpic fruit could be induced by 1-(2-chloro-4-pyridyl)-3-phenylurea (CPPU, an active CK) in tomato (Solanumlycopersicum cv. Micro-Tom). The fresh weight of CPPU-induced parthenocarpic fruits was co...

Parthenocarpic fruit development (PFD) reduces fruit yield and quality in grapevine. Parthenocarpic seedless berries arise from fruit set without effective fertilization due to defective pollen germination. PFD has been associated to micronutrient deficiency but the relation of this phenomenon with pollen polymorphism has not been reported before. In this work, six grapevine cultivars with diff...

The problems associated with caprification (pollination) of Calimyrna figs and the desirability of standardizing or, still better, eliminating this cultural operation have been discussed (5). Because of its relatively low cost, low required concentration, and complete lack of injurious effects on fruit and foliage, para-chlorophenoxyacetic acid was found, during the season of 1948, to offer con...

Fruit growth and development depend on highly coordinated hormonal activities. The phytohormone gibberellin (GA) promotes growth by inducing degradation of the growth-repressing DELLA proteins; however, the extent to which DELLA proteins contribute to GA-mediated gynoecium and fruit development remains to be clarified. Here, we provide an in-depth characterization of the role of DELLA proteins ...

Parthenocarpy is a trait in which fruit set and development are induced without fertilization, thereby contributing to labor saving production. In Cucurbita species, parthenocarpic cultivars have been reported pepo, but not maxima moschata. this regard, the identification of clarification their characteristics will contribute greatly research breeding species. study, we aimed genetically screen...

The objective of the research was to assess a grade of parthenocarpic fruit and fruitsetting following cross-pollination and self-pollination in pepino plants (Solanum muricatum Ait.). An experiment with six pepino clones of different origin was set up in glasshouse conditions. Experimental clones were subjected to the following treatments: self-pollination, cross-pollination, and emasculation ...
