摘  要:
以"猎狗5号"高羊茅种子为试材,研究了不同浓度外源锌对高羊茅种子发芽率、发芽势,以及萌发过程种子内可溶性蛋白质、还原糖和总糖含量及淀粉酶活力的影响。结果表明:重金属Zn处理后降低了高羊茅种子的发芽率和发芽势,使种子萌发整齐度下降。Zn处理使萌发初期高羊茅种子的淀粉酶总活力和可溶性总糖含量上升,但使α?淀粉酶活力、可溶性蛋白质和还原糖含量下降。

摘  要:
Taking Festuca elata‘Liegou NO.5'seeds as the test materials,the effect of different concentration of external source zinc on Festuca elata seed germinating capacity,germinating energy,the protein contents,the reducing sugar and total sugar contents and the amylase activity were studied.The results showed that Zn inhibited Festuca elata's seed germination,reduced the germinating energy.Different concentration of Zn had a certain promoting effect on the amylase activity and the soluble sugar contents,but lowered theα?amylase activity and the contents of soluble protein and reducing sugar at the initial stage of Festuca elataseed germination.
