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...

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...

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...

We investigate the nature and duration of incompatibility between certain combinations of Acromyrmex leaf-cutting ants and symbiotic fungi, taken from sympatric colonies of the same or a related species. Ant-fungus incompatibility appeared to be largely independent of the ant species involved, but could be explained partly by genetic differences among the fungus cultivars. Following current the...

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...

Abstract The tomato ( Solanum lycopersicum L.) is one of the most important vegetables grown globally. However, production tomatoes restricted by Fusarium oxysporum f. sp. lycopersici (Fol). This study aims to investigate ability Fol-resistant genotypes be a rootstock for susceptible cultivar. In this study, cultivar was grafted on rootstocks same species (intraspecific), and grafting compatibi...

Symbioses between leguminous plants and soil bacteria known as rhizobia are of great importance to agricultural production and nitrogen cycling. While these mutualistic symbioses can involve a wide range of rhizobia, some legumes exhibit incompatibility with specific strains, resulting in ineffective nodulation. The formation of nodules in soybean plants (Glycine max) is controlled by several h...
