摘  要：
本文首次在木本植物构件层次上探讨了生殖配置的大小依赖性与权衡问题。据测定,麻疯树果期生殖构件生殖部分的绝对配置为7 g,相对配置为23%,分别变动于2.088 g~22.05 g和7%~49%之间。据回归,生殖构件的营养和生殖部分相对配置为直线负相关,为权衡关系。以构件生物量为大小指标,与麻疯树生殖的绝对配置符合开口向下的抛物线模型,而与生殖的相对配置之间关系符合开口向上的幂函数模型。麻疯树生殖构件两类生殖配置的大小依赖性的曲线模式不同,在不同样地、不同层次都存在普遍性和一致性。构件水平上生殖的相对配置与绝对配置关系模型变化趋势相反,与个体生殖的绝对和相对配置不同。在生产上,需要把优化生殖构件大小,人为修枝,提高当年生殖产量。

摘  要：
The relationship of tradeoff and size dependency about reproductive allocations of woody plants were firstly discussed at the modular level in this paper.In terms of measurement,the Absolute allocation of reproductive part in the reproductive module was 7 g,and relative allocation was 23%,which varied respectively from 2.088 g to 22.05 g and from 7% to 49%.According to the curve regression,there was a negative correlation between relative allocations of vegetative part and reproductive part of the reproductive module,which was a tradeoff relation.Indexing the biomass of the reproductive module,vegetative biomass,and leave and new branch as size,there were a nonlinear parabolic model with a down curve between size and Absolute allocation of the reproductive module,and a nonlinear power model with an up curve between size and relative allocation in module.The reproductive module of Jatropha curcas had two types of reproductive pattern of Absolute and relative allocation of reproduction,which had a commonness and consistency in the different plots and different ranks.Compared to the reproductive allocation of the individual,there were counter curve models between Absolutely and relatively reproductive allocations.Practically,the module size needed optimization and artificially cutting the branches was done to enhance the reproductive productivity.
