栀子几个主要数量性状的相互关系研究

Interaction between Six Quantitative Traits of Gardenia jasminoides

以孝感市孝南区西河镇的成年栀子林为试材,对栀子的6个数量性状进行了相关分析、通径分析和主成分分析。结果表明:单株果数和单位面积产量,应作为丰产栽培选择的重要性状;树高和冠幅主要是通过单株果数来影响单株产量,在生产中要注意协调好树高、冠幅和单株果数的关系;单果重也可适当考虑。

Correlation analysis, path analysis and principal component analysis of the six quantitatire traits of the Gardenia jasminoides from Xihe town of Xiaonan district in Xiaogan city were conducted. Results showed that the number of fruit per plant and yield per area were the most important yield components. Attention to harmonize the relationship between height of plant, crown extent and the number of fruit per plant must be paid. The weight per fruit had positive relation to the yield per plant as well.
