摘要: 在新疆气候生态条件下,以加工番茄(Lycopersicon esculentum Mill)为材料,研究土壤水分对加工番茄叶片叶绿素荧光参数日变化的影响。结果表明,最大荧光(Fm),可变荧光(Fv),最大光化学效率(Fv/Fm),PSⅡ的潜在活性(Fv/Fo)日变化均呈高-低-高的变化趋势,固定荧光(Fo)和表观光合电子传递速率(ETR)日变化均呈低-高-低的变化趋势,其中Fm,Fv,Fv/Fo,Fv/Fm在16:00时降到最低,Fo在16:00时达到最高,ETR在13:00时达到最高。随着土壤水分的降低,Fm,Fv,Fv/Fo,Fv/Fm降低,Fo和ETR增加,表明水分胁迫使加工番茄叶片光系统Ⅱ受到伤害,光系统Ⅱ原初光能转换效率、光系统Ⅱ潜在活性受到抑制。

Abstract: The experiments were made with tomato. It was studied that effect of soil water content on diurnal changes of chlorophyll fluorescence parameter of tomato. The results indicated that maximum fluorescence (Fm), variable fluorescence (Fv), the ratio of the variable to maximum fluorescence (Fv/Fm), the ratio of the variable to minimal fluorescence (Fv/Fo) varied in a high-low-high shape manner, while the minimal fluorescence (Fo) and the electron transport rate (ETR) varied in a low-high-low shape manner, Fm, Fv, Fv/Fm, Fv/Fo reached their lowest points at 16:00, Fo reached its highest point t 16:00, ETR reached its highest point at 13:00. Under water stress, Fm, Fv, Fv/Fm, Fv/Fo decreased, while Fo and ETR raise. Analysis indicated that photosystem Ⅱ damaged, and primary light energy conversion of PSⅡ (Fv/Fm), potential activities of PSⅡ (Fv/Fo) decreased, photosythetic primary action inhibited.
