【摘要】 通过在番茄果实坐果期至白熟期之间设置的多个遮光起始点,研究了番茄坐果期、核桃大小、绿熟期和白熟期开始遮光对番茄褐变型筋腐病发生的影响,结果表明:不论实际光照强度多大,在果实白熟期遮光均会显著促进筋腐病的发生,可以认为果实白熟期是番茄筋腐病对弱光诱导的敏感期。过早地进行遮光会使番茄植株生长势减弱,反而减轻了对筋腐病的诱发作用。更多还原

【Abstract】 Tomato (L. esculentum (L. ) mill. ) plants, cv. Jiafen 10. were shaded with PE net (luminousness ≈ 75%) at 4 beginning points between fruit setting to fruit turning to white during different seasons. The results indicated that shading beginning at the end of fruit mature green period could increase the occurrence of tomato blotchy ripening fruit (BRF) significantly, no matter how high the light intensity was. The vegetative growth of tomato plants showed excess while shading was given at fruit setting period, but there were no significant affects on BRF.更多还原
