to evaluate morphological markers linked with drought stress resistance for screening almond genotypes in the breeding programs the effect of drought stress was studied on six nominated almond genotypes seedlings. the six pre-selected water stress mimposed almond genotypes included: homozygote sweet (butte from university of california), heterozygote sweet (shahrood12, shahrood18, shahrood21 an...

Some endemic shrubs in arid and semiarid ecosystems are in danger of extinction, and yet they can play useful roles in maintaining or restoring these ecosystems, thus practical efforts are needed to conserve them. The shrubs Amygdalus pedunculata Pall., Amygdalus mongolica (Maxim.) Ricker and Ammopiptanthus mongolicus (Maxim. ex Kom.) Cheng f. are endemic species in arid and semiarid regions of...

In this research, a factorial 4×3×4 with 4 replications in Completely Randomized design was used to study the effects of different auxin treatments (4 levels), pH(2 levels) and cultivars (3 levels) on regeneration and rooting of in vitro shoot tips excised from shoots cultured on media supplemented with 1.5-2 mg/l BA. The results showed both auxins (NAA and IBA) produced callus in the bases of ...

A substantial area of the new almond plantations in Spain is under irrigation but because water scarcity, deficit (DI) strategies have to be adopted. This study assesses long-term sustainability different DI over 6 years (2014–2019) on a mature [Prunus dulcis (Mill) D.A. Web] orchard southern Spain. Four treatments were imposed: full (FI); two moderate DI, (SDIM) and (RDIM), where applied was 6...

The almond, which is a member of the Rosaceae family, is the fruit of the almond tree (Prunus dulcis). It has a hard endocarp that contains a seed covered by a rough, brownish skin. Unlike other prunoid fruits, which have an edible mesocarp and an outer skin known as the epicarp, the almond fruit has an epicarp and a mesocarp that are diffi cult to separate and have no nutritional or commercial...
