【摘要】 本文研究了Cu⁺²对小麦种子发芽率、淀粉酶活性和淀粉粒水解率的影响,结果证实,Cu⁺²浓度≥200ppm时,对小麦种子发芽率、淀粉酶活性和淀粉粒水解率均有明显抑制作用,Cu⁺²浓度≥50ppm时,胫根发育受到抑制,Cu⁺²浓度≥100ppm时,胚根短而粗,呈珊瑚状。更多还原

【Abstract】 In this paper it has been studied that the effects of ion Cu⁺² on the germinating percentage, the amylase actirity, and the amylolysis percentage of the wheat seed during germination. It has been proved that if the ion Cu⁺² concentration is greater than 200ppm, the germinating percentage, the amylase activity and the amyolysis percentage will be inhibited obviously if it is greater than 50ppm. the radicle developing will be-inhibited; if it is greater than 100ppm, the radicle will present to be short and thick and coralloid.更多还原
