芽期NaCl胁迫下不同基因型芝麻的反应差异研究
Genotypic variation in sesame salt tolerance during germination under NaCl stress
摘要
Abstract
Effect of NaCl on seeding emergence and growth of sesame during germination was analyzed .The results indicated a modest effect on seeding emergence of NaCl treatment with the range of 0% ~0 .4% .Length of bud and sim-ple vigor index decreased continuously with increasing of concentration of NaCl .The root length and seeding fresh weight varied with sesame cultivars .Some increased first but decreased later with increasing concentration of NaCl ,while others decreased continuously .The 0 .4% NaCl treatment led to a significant decrease in root length ,length of bud ,seeding fresh weight and simple vigor index ,indicating that this could be used as reference concentration for screening and identi-fication of salt tolerance in sesame germplasm . The cluster analysis divided the 39 germplasm into two groups , 12 germplasm with salt tolerance and the others being salt sensitive .In addition ,there was minimal difference in salt toler-ance between newly released cultivars and local salt tolerance cultivar .关键词
