药食两用黄栀子农艺性状的比较及其相关性

为给黄栀子的资源评价及良种选育提供理论参考和指导,对引种栽培的各类型黄栀子的树高、冠幅、叶片性状、果实表型性状以及单株产量等主要农艺性状进行了评价及相关性分析。结果表明:各类型黄栀子农艺性状间差异显著,主要经济性状间存在极显著差异。LH黄栀子多数农艺性状均优于其它类型黄栀子。在果实纵横径、单株果数以及单株产量等方面尤为明显。黄栀子单果鲜质量及单株果数与单株产量呈极显著相关性,相关系数分别可达0.989和0.929;果实纵横径、树高及冠幅与单株产量相关性均达到极显著水平,但萼长及叶片相关性状与产量相关性不显著。

Comparisons of main agronomic characters and interrelationships of edible and medicinal plantGardenia jasminoides

In order to some provide theoretical references and guidance for resource evaluation and breeding ofGardenia jasminoides, the main agronomic characters of four cultivation types ofG. jasminoides were evaluated and analyzed through correlation analysis, including tree height, crown width, leaf character, fruit phenotypic characters and yield per plant. The results showed that, the agronomic characters had signiifcant differences in the four main cultivation types, and there were extremely signiifcant differences between main economic characters. Most agronomic characters of LH G. jasminoideswere better than those of other cultivation types, especially, longitudinal and transverse diameters of fruit, fruit numbers and yield per plant, and so on. Fresh fruit mass, fruit number per plant was signiifcantly correlated with yield per plant, the correlation coefifcients were 0.989 and 0.929, respectively. Longitudinal and transverse diameters of fruit, tree height, crown width were extremely signiifcantly correlated with yield per plant, but calyx length and leaf characters had no signiifcant correlation with yield.
