盐胁迫下工业大麻苗期生理生化特性的研究

Research on the Physiological and Biochemical Features of Industrial Hemp under Salt Stress

土地盐碱化是限制农作物生长的重要因素,工业大麻具有较强的抗逆性和适应性.研究以"巴马火麻"为试验材料,幼苗期进行盐胁迫处理,通过测定和分析盐胁迫下不同时间叶片SOD、可溶性蛋白及可溶性糖含量的变化,探讨盐胁迫对工业大麻生理生化的影响.结果表明:盐胁迫下工业大麻叶片SOD活性持续增高,第6 d达最大值;可溶性糖含量在各个胁迫时期与对照差异无统计学意义;可溶性蛋白含量则先增加后降低,第4 d达最大值.

Soil salinization is one of the important factors to limit crop growth, but industrial hemp has the stronger resistance and adapt-ability to environment. Taking industrial hemp^BAMA^ as the experimental material, we measured and analyzed the changes of leaf SOD, soluble protein and soluble sugar content at the seedling stage under different time of salt stress. According to the research data, We discussed the physiological and biochemical influence of salt stress on hemp. The results showed leaf SOD activity increased continu-ously under salt stress, the maximum at the sixth day; soluble sugar content was no statistically significant difference compared with con-trol at each stress period; soluble protein content reduced after increased at first,the maximum value at the fourth day.
