| 摘 要： | 以无限生长型番茄品种金鹏1号为试材,采用回归分析、相关分析和通径分析法研究了春茬番茄器官发育(包括株高H、绿叶数L、坐果率F、果实体积V)与环境要素的动态关系。结果表明:对株高变化影响最大的环境因子是X1(上午光合有效辐射积),而X5(周均上半夜有效地温积)和X2(周均下午光合有效辐射积)主要是通过X1而间接影响株高的变化;对绿叶数变化影响最大的环境因子是X5,而X14(周均下半夜有效气温积)主要是通过X5而间接影响绿叶数的变化;对坐果率变化影响最大的环境因子是X4(周均下午有效地温积),而X11(周均上午有效气温积),X13(周均上半夜有效气温积)、X14、X6(周均下半夜有效地温积)和X12(周均下午有效气温积)主要是通过X4而间接影响坐果率的变化;对果实体积变化影响最大的环境因子是X3(周均上午有效地温积),而X12、X13、X11和X6主要是通过X3而间接影响果实体积的变化。

| Abstract: | Taking unlimited growth type tomato Jinpeng No.1 as test material,the dynamic relationship between the development of tomato organs(plant height(H),the number of green leaves(L),the rate of fruit set(F) and fruit volume(V)) and environmental elements were studied using regression analysis,correlation analysis and path analysis.The results showed that X1(accumulated photosynthetic radiation of weekly mean value in the morning)had the greatest effect on the changes of H,while X5(accumulated effective soil tem... |
