self-incompatibility is one of the main problems in almond production. in this research work, at the first step, some local cultivars as well as some imported ones were evaluated from the point of their male and female organ compatibility. then, ten selected commercial self-incompatible cultivars(female parents) were crossed with two self-compatible cultivars(male parents) i. e. tuono and super...

a principal obstacle facing intensive pear orchard establishment in iran is the absence of appropriate dwarfing or semi-dwarfing rootstocks, compatible with commercial cultivars, as well as showing adaptability with alkaline soils. this research aimed at an evaluation of the hawthorn seedlings (crataegus sp.) as a potential dwarfing rootstock for pear and a comparison of its dwarfing effects wi...

most sweet cherry (prunus avium l.) cultivars are self-incompatible and have problems of ‎fertilization and fruit set. to produce commercial crops they need compatible and suitable ‎pollinizers. the compatibility of “zarde daneshkadeh”, “protiva”, “sorati lavasan”, “haj-yosefy” ‎and “meshkin shahr” cultivars with “shoa-o-saltaneh” as seed parent studied in a randomized ‎complete block design (r...

sweet cherry (prunus avium l.) is considered as one of the most important temperate zone fruits worldwide. it is an economical fruit with high demand because of its early ripening fruits that enter the market early in the season. most sweet cherry cultivars are self-incompatible, not able to produce commercial fruit without being pollinated with a compatible pollinizer. in the present study, fl...

breeding of almond to attain self compatible cultivars is among the objectives followed in almond breeding. early identification of self-compatible genotypes from self-incompatible ones is very important in saving of time and expenses. there are different methods of either classical or molecular nature to recognize self-compatibility in genotypes. in this study, pcr-based method with specific p...

The effects of different Cucurbita spp. rootstocks on melon cultivars belonging to different horticultural groups were studied by comparing grafted plants with non-grafted ones under greenhouse and open ®eld growing conditions. Winter melons (Cucumis melo L.) of the Inodorus group, cvs. `Thraki', `Peplo' and `Lefko Amynteou', and a summer melon of the Cantalupensis group, cv. `Kokkini Banana', ...

most sweet cherry cultivars are as found as self-incompatible and therefore for commercial fruit production, compatible pollinizers are needed. controlled pollination and microscopic examination of pollen tube growth in the style are two classical methods for determination of compatible and incompatible pollen donor cultivars. this experiment was carried out to explore the compatibility of ‘zar...

18 The effect of the pollination time and of the pollen origin was studied in three self-compatible 19 and late-blooming almond genotypes in order to evaluate their effect on fruit set and yield. 20 The full self-compatibility of the three genotypes was clearly assessed as fruit sets after self21 pollination were similar to those obtained after cross-pollination with pollen from two 22 differen...

The almond, Prunus dulcis Miller which belongs to Rosaceae family, is one of the most important commercial and oldest cultivated tree nut crops. Almonds are classified as a ‘nut’ in which the edible seed is the commercial product. Therefore, pollination and fertilization are necessary in almond. The characteristic of cultivated almond to express gametophytic self- incompatibility discourages se...

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...
