With climate change, pea will be more frequently subjected to heat stress in semi-arid regions like Saskatchewan during flowering. The pollen germination percentage of two pea cultivars was reduced by heat stress (36°C) with an important decrease in cultivar 'CDC Golden' compared to 'CDC Sage.' Lipids, protein and other pollen coat compositions of whole intact pollen grains of both pea cultivar...

rapid germination is an important factor determining the final yield. the most important abiotic stress threatening lentils is drought and temperature. therefore, this study was performed with the aim of investigating effects various thermal treatments (5, 10, 15, 20, 25 and 30°c) and four levels of drought (0, -4, -8, -12 and -16 bar) on percentage and germination rate of lentil genotypes. a s...

zafar as a new rapeseed cultivar is the cross which was made between 19h and sarigol line/cultivar in 2003. the pedigree selection was applied to mange the segregating generations. the results of evaluation made during 2008-09 and 2009-10 showed that zafar with an average seed yield of 3810 kg ha-1 was among superior genotypes identified. further evaluation on these genotypes as a mid-maturity/...

environmental conditions including metrological parameters (precipitation, temperature, humidity and etc.) various stresses and nutrition, could affect  germination and  seeds vigor during of development, ripping and leven after harvesting of soybean seed. for this, experiments of completely randomized design ( as nested)by four replications were performed in seed laboratory of gorgon universit...

Production of high quality seeds is of fundamental importance for successful crop production. However, knowledge of the effects of increased temperature resulting from global warming on seed quality of alpine species is limited. We investigated the effect of maternal environment on seed quality of three cultivars of the leguminous forage species Vicia sativa, giving particular attention to temp...
