葡萄对SO_2伤害的敏感性与吸收SO_2途径的探讨

Study on sensitivity of grope plant to SO_2 and its absorption mechanism

用不同用量的SO2对8个葡萄品种进行处理,研究了葡萄对SO2伤害的敏感性与吸收SO2的途径。结果表明,不同品种葡萄对SO2的敏感性及伤害部位不同,8个待测品种按对SO2敏感性的不同可被分为四类;果实中SO2具有累积效应,葡萄对SO2的敏感性不同,吸收SO2的途径和能力也不同。

Eight grape cultivars were treated with different SO2 doses and their sensitivity to SO2 and absorbing mechanism of SO2 were studied.The results showed that the sensitivity to SO2 and injured part were different in the different grapes. The eight grape cultivars can be classified to four types according to the sensitivity to SO2. SO2 can accumulate in the grapes. The sensitivity of grapes to SO2 was different, and the way and ability of absorbing SO2 was also different.
