lants have evolved a variety of reproductive systems. The trees of some species, -L such as ash and ginkgo, are differentiated by gender, with both a female and a male individual required for seed production. Other species, such as cherries and almonds, ensure cross-pollination without separating individuals by gender: each plant is self-incompatible, so that stigmas cannot be fertilized by pol...

almonds are self incompatible, the incompatibility being controlled by a multi allelic (s-alleles) single gene. the incompatibility alleles were studied in 96 samples of wild almonds and related prunus species from 10 taxonomic groups. polymerase chain reactions were carried out with six primer sets including: three degenerate primer pairs (paconsi-f(fam)/em-pc1consrd, paconsi-f(fam)/em-pc3cons...

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...

The measured metabolizable energy (ME) of whole almonds has been shown to be less than predicted by Atwater factors. However, data are lacking on the effects of processing (roasting, chopping or grinding) on the ME of almonds. A 5-period randomized, crossover study in healthy individuals (n = 18) was conducted to measure the ME of different forms of almonds (42 g per day), as part of a controll...

almond (prunus dulcis [webb] d.a. mill) is an economically important species of genus prunus (rosaceae, subfamily prunoideae). the commercial edible part of almond fruit is kernel. fertilization is essential for nut production in almond but most cultivars are self or even cross-incompatible. self-incompatibility in almond is gametophytic and controlled by a single s-locus with multiple codomina...

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...
