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...

ABSTRACT In the world consumption of strawberries is very appreciated, both in natura or industrialized form. Brazilian production depends on importation strawberry seedlings from countries such as Spain, Chile and Argentina, which are cultivars improved temperate climates and, consequently, not well adapted to tropical conditions. Thus, genetic breeding programs essential for generation more c...

Abstract This study was conducted to evaluate the role of oxidative stress in roots of eight wheat genotypes with different drought tolerance, subjected to drought stress. For analyzing the changes of antioxidant enzymes, native PAGE analyses of protein extract were performed. The roots of wheat seedlings showed one unambiguous isoform of superoxide dismutase (SOD) and catalase (CAT). Eight iso...

The main objective of the present study was to investigate the effects of the frying media and storage time on the fatty acid composition (FAC) and iodine value (IV) of deep-fat fried potato chips. The frying experiment was conducted at 180oC for five consecutive days. Six frying media were considered as the main treatments: refined, bleached, deodorized (RBD) palm olein (A), canola oil (C), RB...

Although pollen tube growth has been an important criterion for self-compatibility evaluation in almond, there is not a clear-cut separation between positive and negative growth of pollen tubes in the different genotypes. The examination of pollen tube growth after selfing almond seedlings has allowed establishing different levels of compatibility, but not a clear-cut separation between self-co...

In the present study fifty genotypes of Brassica juncea were evaluated for heat stress tolerance in terms of biochemical components, in four day old seedlings. Heat shock was given at 45 degrees C for 4.5 hr and thereafter survival percentage, electrolyte leakage and chlorophyll content were estimated. Tolerant genotypes (10) registered survival greater than 65%, moderately tolerant (20) betwee...

In this study, walnut genotypes that were selected during two growing seasons among thousands of seedlings analyzed in terms detailed morphometric, phenological, and chemical traits. A multivariate analysis was conducted with valuable traits for breeding selection such as morphometric traits, composition, phenological characteristics. Also, characterized by a retrotransposon-based iPBS marker s...
