摘要 为探索源库比例和源库距离对温室番茄同化产物分配的影响规律,2016年1—12月在江苏大学Venlo型试验温室中进行试验,分为早春茬和秋冬茬,采用双杆整枝,设置了3个留果数水平(T1留3果;T2留2果;T3留1果)和2个不同源库距离(T4第1果枝留1果;T5第2果枝留1果),采用已建立的叶长与叶干质量、株高与茎干质量和果径与果干质量的数学公式来计算各器官的同化产物动态变化.结果表明:T1,T2和T3之间的同化产物产量差异不大,但均高于T4和T5,T4和T5之间差异不大.同化产物向果实的分配系数在处理后22 d T1显著大于T2和T3;处理T4同化产物向果实中分配系数在处理后16 d显著大于T5.不同处理间源库比例和源库距离均影响温室番茄同化产物分配,这为温室番茄的整枝管理提供了理论依据和技术支持.
In order to explore the effect of sink/source ratio and distance between sink and source, a study was conducted at Venlo type experimental greenhouse of Jiangsu University from January to December 2016. Experiment was divided into the autumn-winter season and early spring of crop stubble with double stem pruning. Treatments were three left fruit levels(T1 left 3 fruit; T2 left 2 fruit; T3 left 1 fruit)and two distance between sink and source(T4, left 1 fruit of the first branch; T5, left 1 truss of the second branch). The established mathematical formula of leaf length and leaf dry weight, stem height and weight, and fruit diameter and fruit dry weight were adopted to calculate the dynamic changes of various organs. The result showed that dry matter productions between T1, T2 and T3 had no significant differences, but were higher than those of T4 and T5. Partitioning coefficient of T1 was significantly higher than that of T2 and T3 after 22 days treatment. And partitioning coefficient of T4 was significantly higher than that of T5 after 16 days treatment. The results showed that the sink/source ratio and distance between sink and source could affect dry matter partitioning, which should provide a theoretical basis for pruning management of greenhouse tomato.
