大豆种子萌发过程中０．１－１ｍ／Ｌ三价砷（ＮａＡｓＯ＿２）对大豆种子萌发有促进作用，但随砷浓度提高，发芽率有所下降；三价砷浓度达７５ｍｇ／Ｌ时，种子萌发完全受到抑制。种子吸胀过程中砷毒害主要使膜修复系统受到损伤；种子正常吸水萌动后受到砷毒害则导致膜脂过氧化作用、丙二醛含量增加、膜渗漏率增加．砷对异柠檬酸裂解酶和超氧物歧化酶活性的影响与发芽能力呈正相关。
During the germination of soybean seeds, 0.1-1 m / L arsenic trioxide promoted the germination of soybean seeds, but with the increase of arsenic concentration, the germination rate decreased. When the trivalent arsenic concentration reached 75 mg / L, the seed germination Completely inhibited. The arsenic poisoning in the process of seed dilatation mainly caused the membrane repair system to be damaged. The normal poisoning of seeds caused germination of arsenic resulted in membrane lipid peroxidation, increased MDA content and increased membrane leakage rate. The effect of arsenic on isocitrate lyase and superoxide dismutase activity was positively correlated with germination ability.
