长白山区红刺玫花构件生物量与其花径的相关性分析

Correlation Analysis of Rosa rugosa Flowers Modular Biomass and Flowers Size in Chang-bai Mountain Area

[目的]进行红刺玫花构件结构及其生长规律的研究。[方法]采用大样本、随机取样方法分析长白山区红刺玫花构件结构和不同时间条件下红刺玫花构件的生长规律。[结果]在不同时间红刺玫花径大小与花生物量、花被生物量、花蕊和花托之和生物量之间均有着密切的正相关关系,其相关程度最佳的均为线性函数,并且b值都不同;都存在表型可塑性,但相同的函数变化蕴涵着不同时间它们具有相同的形成规律。[结论]该研究可为红刺玫的高效利用和科学管理,以及栽培、建植红刺玫人工和半人工灌丛提供理论依据。

[Objective]The research aimed to study the structure of floral modular and its growth rule of Rosa rugosa. [Method]Big samples and random sampling method were used to investigate morpha of R. rugosa modular biomass and floral diameter which grow in Chang-bai mountain area.[Result]The results showed that there was a positive correlation between the sizes of floral diameter of R. rugosa and the coefficients of the floral envelope,flowers and floral of the sum of receptacles and stamen of R. rugosa in different times. The best correlation was the linear function. There were different b values in the increasing coefficients of the floral envelope and flowers of R. rugosa in different times. And there are differences in growing speed in the coefficients of flowers growing with the floral diameter in different time. All the coefficients of flowers and floral envelope had formal plasticity,but there was a same forming rule in the same changing of functions in different times. [Conclusion]This research could provide theoretical basis for the efficient use and scientific management of R. rugosa and for the planting,set up of man-made and half man-made R. rugosa bushwood.
