摘要 以大豆 GlycinemaxMerr. 为实验材料,研究了CO2激光不同功率密度和不同时间处理对大豆种子发芽率、淀粉酶活性、可溶性蛋白质、可溶性糖含量和氨基酸含量的影响.结果表明: 1 16mw/mm2、18mw/mm2、20mw/mm2CO2激光处理均能提高种子发芽率、淀粉酶活力、可溶性蛋白质、可溶性糖含量和游离氨基酸含量,其中18mw/mm2CO2激光处理效果最好; 2 相同功率 18mw/mm2 不同时间处理均能提高种子发芽率、淀粉酶活力、可溶性蛋白质和游离氨基酸含量,处理时间以75s效果最好. The effects of CO_2 laser treatment on seeds germination capability, protein content, soluble saccharine content, and amylase activity and amino acid content of Glycine max Merr. have been studied. The results indicate: (1)different density of CO_2 laser treatments(16 mw/mm^2,18 mw/mm^2,20 mw/mm^2) have improved germination capability, protein content, soluble saccharine content, and amylase activity and amino acid content of soybean seeds or shoots. Compared with control, the treatment of 18 mw/mm^2 is the best one among three treatments.(2)different time treatments(the treatment of 18 mw/mm^2) have also enhanced germination capability, protein content, and amylase activity and amino acid content of soybean seeds or shoots. The time of 75 s is the best one among the treatments.
