| 摘 要： | 对雌雄异株植物毛白杨抗药性的性别差异测定表明:1、雌株对氧化剂的抗性小于雄株,受害严重;2、雌株对还原剂的抗性大于雄株;3、雄株氧化还原电位均高于雌株;抗药性与氧化还原电位在氧化剂中表现为正相关,在还原剂中表现为负相关;4、这种试验的结果在成株和幼株间表现完全一致。

| Abstract: | The determination of the drug resistance in dioecious plant (Populus tomentosa) showes as followes:1.The female plants resistance to the toxic action of oxidant is less than the mqle plants, but the maleplants just be opposite from the female plants. 2. The female plants resistance is more than the male plantsin reductant. 3. The drug resistance and oxidation-reduction potential is interrelated, both is positive cor-relation in oxidant and that is negative correlation in reductant. 4. In general oxidation-reduction poten-tial of the male plants is more than the female plants. 5. The young trees determination is shown that fullyagree with the adult plants. |
