摘要
以番茄品种辽园多丽为试验材料,在日光温室内对植株生长期各器官干物质分配及单个果实生长发育进行了研究。结果表明:番茄在开花结果后,地上部分配指数保持在0.9以上,地下部分配指数维持在0.1以下,同化物大多供给地上部用于茎、叶、果的生长;番茄果实横径与发育时间呈"S"形曲线变化规律,并利用Logistic方程建立番茄果实生长的模型。
＂Liaoyuanduoli＂,a tomato cultivar, was conducted in the greenhouse to study the dry matter of various organs during plant growth period and the individual fruit developing. When the plant was in blossom, the distribution index of above ground parts remained above 0.9, while the root system was below O. 1. Most of the assimilation supply the developing of the stems, leaves, and fruit. The pattern of tomato fruit developing in horizontal diameter appears ＂S＂. Further
