Early-flowering species may be especially susceptible to occasional pollen limitation and, therefore, may benefit from a mixed-mating strategy that provides reproductive assurance. We studied cleistogamous (CL) and chasmogamous (CH) fruit set of spring-flowering Viola praemorsa Dougl. ex Lindl. along an elevational gradient in the Rocky Mountains, testing whether pollen limitation or allocation...

The reproductive capacities of dioecious plant species may be limited by severe pollen limitation and narrow seed shadows for the two reasons. First, they are unable to self-pollinate, and seed production occurs only with pollinator movement from males to females. Second, only 50% of the individuals in populations contribute to seed production. Despite these handicaps, dioecious plants maintain...

Abstract WRKY transcription factor plays important roles in plant growth and resistance, but only a few members have been identified strawberry. Here we FvWRKY50 diploid strawberry which played essential vegetative reproductive growth. Knocking out by genome editing accelerated flowering time leaf senescence delayed anthocyanin accumulation fruit. Further analysis showed that acted as transcrip...

Bihar is known as hub of litchi production not only in India but also in the world due to its quality fruit. Entire country people desire to taste this fascinating fruit having unique fragrance and high demand during the season. The plant is highly specific to climatic condition and soil requirement and probably due to which its cultivation is restricted to the few countries in the world. Fruit...

effects of nitrogen fertilization timing close to the beginning of short-day period and white mulch on flowering and yield components have been studied in ‘paros’ and ‘queen elisa’ strawberry cultivars. split plot experiment in a randomized complete block design with eight treatments (two mulch treatments × n fertilization during four different times from last week of august to third week of se...

in order to select of the best nectarine cultivars in meshkinshahr environmental condition, 11 cultivars of nectarines (including: independence, star redgold, stark sunglow, sanking, quata, shabrang e karaj, germez-e-paeez-e-mashad and 4 new imported cultivars including: winberger, vega, orion and gioia) were grafted on misory peach rootstock. cultivars were planted in randomized complete block...

In grapevine, fruit abscission is known to occur within the first two to three weeks after flowering, but the reason why some berries in a cluster persist and others abscise is not yet understood. Ethylene sensitivity modulates abscission in several fruit species, based on a mechanism where continuous polar auxin transport across the pedicel results in a decrease in ethylene perception, which p...

Olive is one of the most ancient fruit trees and has been cultivated for its oil for thousands of years. A mature olive tree produces about 500,000 flowers. They are borne on inflorescences termed panicles. The number of flowers and their distribution on the inflorescence are specific for each cultivar but can change from year to year. The flower position on the inflorescence affects its gender...

The present study was carried out in 2017–18 at ICAR-NRC on Litchi, Muzaffarpur to assess the effect of temperature, flowering time and inflorescence length yield litchi (Litchi chinensis Sonn.) cv. Shahi. revealed that stage as well were positively correlated with florescence width (0.98) while fruit set negatively temperature (-0.863). There a strong correlation between size inflorescence. Ea...

A breeding program searching for new peach and nectarine varieties adapted to the Ebro Valley growing conditions is being developed at the Aula Dei Experimental Station (CSIC). This program evaluates 15 populations obtained by controlled crosses. Different agronomic parameters such as blooming date, yield, and ripening date were determined in these populations. Quality traits such as fruit type...
