摘要： 摘要：通过TOMSIM模拟与温室试验研究了同步叶片修剪对温室番茄品种 “Capita”干物质生产与分配的影响。结果表明, TOMSIM模拟试验与温室试验相当吻合。同步叶片修剪，一方面，显著降低LAI与生长率，从而导致单位面积植株总干重的显著降低；另一方面，显著减少营养生长库强，有利于干物质分配到生殖生长库器官，提高果实累积干物质分配率，从而补偿因单位面积植株总干重降低而引起的果实干重的降低。植株密度对果实累计干物质分配率没有显著影响，增加植株密度能增加LAI。同步叶片修剪加高密度能显著提高单位面积果实干重。

Abstract: Abstract：Effect of synchronous leaf pruning on production and distribution of dry matter in greenhouse tomato cultivar ‘Capita’ was investigated by both a TOMSIM simulation and a greenhouse experiment. The results indicated that the values between simulation study and greenhouse experiment were fitted very well. With synchronous leaf pruning, on one hand, LAI and growth rate were significantly decreased, which resulted in a significant reduction in total plant dry weight per square meter; on the other hand, the vegetative sink strength was decreased and the distribution of dry matter allocated to generative sinks was favored, which resulted in a significant increment in the cumulative fraction of dry matter allocated to the fruits and compensated for the reduction in fruit dry weight resulted from that in total plant dry weight per square meter. Plant density has no significant influence on the cumulative fraction of dry matter allocated to the fruits. LAI was increased by increased plant density. Fruit dry weight per square meter was significantly improved in leaf pruning & increased plant density.
