【摘要】 探讨了NaCl胁迫下对低酚棉品种种子萌发的影响。NaCl质量分数在 0 .2 5 %～ 0 .75 %范围内对大多数低酚棉品种种子萌发均产生抑制作用 ,且随NaCl含量的提高抑制作用增强。但低含量NaCl对少数品种的发芽势、发芽率表现促进作用。萌发时同一品种不同性状对盐胁迫表现出较大的差异。中无 15 1、鲁无 40 1、鲁无 16及冀无 2 0 31等表现出较好的耐盐性更多还原

【Abstract】 The effect of salt stress on seed germination of glandless cotton was studied in this paper. The seed germination of major varieties was inhibited from 0.25% to 0.75% NaCl solution for 12 hours. Inhibited effect was the higher in the high NaCl content than that in the low NaCl content. The seed germination of some varieties was accelerated in 2.5% NaCl. There was significant difference to the reaction of salt stress among different traits on the same variety. Zhongwu 151, Luwu 401, Luwu 16, Jiwu 2031 have better salinity tolerance.更多还原
