摘要: NaCl胁迫明显抑制胡萝卜种子萌发,当NaCl浓度为50mmol/L时,种子发芽率下降1/2,当NaCl浓度达到150mmol/L时,种子发芽率下降82.9%;无论NaCl浓度高低,都对胡萝卜幼苗生长产生抑制作用,使幼苗生长量、干物质积累及含水量显著下降。NaCl浓度对叶细胞结构也有很大影响,随着NaCl浓度的升高,细胞核缩小、变形或降解。

Abstract: NaCl stress could distinctly inhibit germination of carrot seed,germinat ion rate decreased half of that when the concentration NaCl was 50mmol/L,and it decreased 82.9% when that was 150mmol/L NaCl stress always inhibited seedling growth no matter what the concentration NaCl was high and low,and made seedling growth amount,dry matter accumulation and water content to decrease effectively.The concentration NaCl largely effected on leaf cell structure,and karyon shinked,distorted or degraduated with rising of the concentration NaCl.

Key words: Salt stress, Carrot, Germination rate, Seedling growth, Karyon
