| 摘 要： | 研究了田间旱育条件下, 在土壤水分充足和适度干旱状态时, 化感水稻"PI312777"和非化感水稻"Lemont"的抑草效应差异.结果表明, 在两种供水状态下, 化感水稻"PI312777"对田间杂草的控制效应显著高于非化感水稻"Lemont","PI312777"对各种杂草抑制效应指数的绝对值多在0.5以上, 而"Lemont"对各种杂草抑制效应指数的绝对值则多在0.5以下.进一步分析发现, 适度干旱胁迫下"PI312777"和"Lemont"对杂草的抑制效应都有增强趋势, 且"PI312777"稻田杂草生物量的降低幅度高于"Lemont"稻田; 以与非化感水稻"Lemont"共生下的杂草生物量为对照, 化感水稻"PI312777"对稻田杂草均表现出一定的化感抑制作用, 且适度干旱胁迫诱导下化感作用强度进一步增加.此外, 水稻对不同杂草的生物干扰强度不同, 化感水稻"PI312777"对夏熟稻田阔叶杂草有较强的控制效果, 干旱胁迫诱导"PI312777"对无芒稗(Echinochloa crusgalli L.)的化感潜力明显增强.
