安宁食用玫瑰产量形态指标与产量的相关分析和通径分析

Correlation and Path Analysis on the Output Morphological Index and Output of Anning Edible Rose

[目的]研究影响安宁食用玫瑰产量的高产形态指标,为玫瑰的高产栽培技术提供参考。[方法]对影响安宁食用玫瑰产量的形态指标进行相关分析和通径分析。[结果]影响安宁食用玫瑰产量的主要形态指标与产量的相关程度由高到低依次为单株花朵数(0.952 7)、单枝花朵数(0.944 5)、茎杆粗度(0.914 8)、茎杆长度(0.749 8)、单花直径(0.057 8)、单花重(-0.801 4),对产量直接影响的重要性由高到低依次为单株花朵数(0.914 3)、单花重(0.298 8)、茎杆粗度(0.287 7)、单枝花朵数(0.171 1)、茎杆长度(0.080 4)、单花直径(0.029 5)等;形态指标间具有明显的制约关系。[结论]在栽培过程中,应创造有利于茎杆增粗、单株花朵数增加、单花重适当增加的栽培技术措施来提高玫瑰产量。

[ Objective] To study high yield and morphological index affecting output of Anning edible rose, and provide scientific reference for high yield cultivation techniques of rose. E Method ] The correlation and path analysis on the morphological index affecting output of the Anning edible rose were done. [ Result ] The relativity of morphological index and output were in turn：number of flowers per tree （0. 952 7 ） ,the flower number of single-branch （ 0.944 5 ）, stem diameter （0.914 8 ） ,length of branch （ 0. 749 8 ）, diameter of single flower （ 0. 057 8 ）, weight of single flower（ -0. 801 4）. The importance of the direct factors on the ouput were in turn：number of flowers per tree（0.914 3） ,weight of single flower （0. 298 8 ）, stem diameter （0. 287 7 ）, the flower number of single-branch （0. t7i 1 ）, length of branch （0. 080 4 ）, diameter of single flower （0.029 5 ）, and so on. The morphological indices had the obvious restricted relations. E Conclusion ] In the process of cultivation,it should create cultivation technical measures which was favorable for stem enlargement,the increase of number of flowers per tree and weight of single flower to increase production of rose.
