almond is one of the most important prunus species. most almond cultivars and genotypes are self-incompatible and some others are cross-incompatible. however, recently self-incompatible cultivars developed by breeding are available. therefore self-incompatible cultivars for pollination, fertilization and production require compatible pollen of other cultivars. in this regard the study of pollen...

There has been a heated argument over self-incompatibilityof chrysanthemum (Chrysanthemum morifolium) among chrysanthemum breeders. In order to solve the argument, we investigated pistil receptivity, seed set, and compatible index of 24 chrysanthemum cultivars. It was found that the 24 cultivars averagely had 3.7-36.3 pollen grains germinating on stigmas at 24 hours after self-pollination throu...

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...

in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...

despite the profusion of flowers that develop on olive trees, only a few set fruit during the growing season and only about 1-2% of the fruit remains on the trees at maturity. therefore, to maximize fruit set and yield, it is important for growers to understand the cross-compatibility between cultivars when planning to establish an olive orchard. this study was carried out in shiraz, fars provi...

The finding of new self-compatible cultivars in local population is a breeder’s objective in order to increase the sources of self-compatibility for the almond (Prunus amygdalus Batsch) breeding programmes. ‘AS-1’, a local Spanish selection, was considered to be self-compatible according to its self pollen tube growth and was incorporated in the almond breeding programme of Zaragoza as a source...

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...

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...
