杨树新造林黑斑型溃疡病病原菌代谢产物对寄主的生理影响

摘要

测定了Phomopsiseucommicola代谢产物对寄主杨树电导率、脯氨酸、过氧化物酶和多酚氧化酶等生理指标的变化。结果表明，病菌代谢产物中可能含有对寄主起一定毒害作用的活性物质。%Physiological indices such as conductance, proline, POD and PPO of poplar were tested after inoculating Pho- mopsis eucommicola. The results showed that metabolites may produce certain toxic effects to the host.
