| 摘 要： | 研究了茭白(Zizania latifolia Turcz.)受食用黑粉菌(Ustilago esculenta)侵染后的生长、抗氧化特性和叶绿素荧光的变化.结果表明,食用黑粉菌侵染导致植株的株高、叶长、叶宽、叶片厚度、根长、茎鲜重、根鲜重和地上部鲜重下降,但分蘖数提高；同时提高了茭白叶片的抗坏血酸过氧化物酶(APX)、过氧化氢酶(CAT)、过氧化物酶(POD)、谷胱甘肽还原酶(GR)、超氧化物歧化酶(SOD)的活性和过氧化氢(H2O2)含量,但却引起超氧自由基(O2-)产生速率和丙二醛(MDA)含量降低.食用黑粉菌侵染提高了叶片的PSⅡ实际光化学效率(ΦPSⅡ)和电子传递速率(ETR),同时降低了非光化学猝灭(NPQ),但对PSⅡ最大光化学量子产量(Fv/Fm)的影响不大.
