【摘要】 研究了不同时期昼间亚高温(35℃)处理对日光温室番茄生产的影响。结果表明,长期35℃昼间亚高温处理,番茄植株相对生长速率降低、净同化率减小,同时番茄生育物候期提前,缩短了植株生育期,提早果实发育,但果实坐果率下降、平均单果重变小,导致果实产量降低;亚高温条件下番茄果实品质下降,处理时期越早,品质下降越明显。更多还原

【Abstract】 Effects of sub-high temperature of daytime(35℃) on the phenophase,yield and quality of tomato in the greenhouse were studied. The results showed as follows, long time sub-high temperature of daytime decreased the relative growth ratio and net assimilation ratio, and advanced the phenophase of plant , and a long period time of sub-high temperature treatments even made the plants decline earlier. The yield of tomato fruits under sub-high temperature treatments decreased and the quality of tomato decreased .更多还原
