摘要： 分别用4个强度的恒定磁场对紫皮洋葱鳞茎进行不同时间的处理.结果表明:一定强度的恒定磁场和处理时间可以降低洋葱鳞茎可溶性蛋白质含量、可溶性糖含量、总淀粉酶活性,提高IAA氧化酶的活性,从而抑制洋葱鳞茎的发芽;可溶性蛋白质含量、可溶性糖含量、总淀粉酶活性与洋葱鳞茎发芽率的高低呈正相关关系,而IAA氧化酶活性与洋葱鳞茎发芽率的高低呈负相关关系.

Abstract: Onion bulbs were treated with four magnetic intensities respectively with different time. The results showed that optimum magnetic intensity and treating time decreased content of soluble protein,soluble sugar and total amylase activity and increased IAA oxidase activity,so the germination percentage of onion bulbs was inhibited. The content of soluble protein,soluble sugar and total amylase activity was correlation with the germination percentage of onion bulbs,but IAA oxidase activity was negative relative to the germination percentage of onion bulbs.
