不同种源辣木生长差异性分析

Growth Difference of Moranga oleifera Lam. from Different Provenances

对从美国、马里、肯尼亚、古巴和德国引种种植的辣木植株进行生长差异性分析,结果表明:不同种源的辣木在不同时间内生长速率各不相同,不同种源的辣木株高、冠幅、地径、分支数等生长指标也存在不同程度的差异性;美国种源的辣木株高、冠幅均表现较好,古巴种源的辣木株高、冠幅、地径和分支数则表现相对较差;美国种源和古巴种源在株高、冠幅、地径生长量上差异显著,马里、肯尼亚、德国种源之间各生长指标差异不显著;综合各项指标, 5个种源中,美国种源的辣木生长表现较好,可作为优良种源开展进一步研究。

The growth difference of Moringa oleifera Lam.introduced from the United States,Mali,Kenya,Cuba and Germany was analyzed.The results showed that M.oleifera Lam.from different provenances had different growth rates in different periods and varied to some extents in growth parameters such as plant height,crown spread,ground diameter and number of branches.The plant height and crown spread of M.oleifera Lam.were better from the provenance of United States,and the plant height,crown spread,ground diameter and number of branches from the provenance of Cuba were relatively poor.There were significant differences in plant height,crown spread and ground diameter between the provenances of United States and Cuban.There were no significant differences in growth indicators among the provenances of Mali,Kenya and Germany.When various indicators were taken into account,Moringa oleifera Lam.from the United States had the best growth among the five provenances,and could be used as an excellent source for further study.
