麻疯树不同种源生长性状及优良单株选择

Jatropha curcas Different Provenances Growth Characteristics and Superior Individual Selection

在广东省湛江市对麻疯树30个种源进行生长观测和优树初选试验,结果表明:各种源间树高、冠幅生长、结果数量都存在极显著差异。经方差分析和Duncan法多重比较表明,219号、222号各个指标相对高,可作优良种源进行早期选择;以结果数100颗.株-1、树高200 cm、冠幅200 cm为标准,在麻疯树30个种源中选出优良单株234A-2、234B-4、219A-5、220A-1、212B-3、225A-1、225A-4、240B-5,可作优良种源进行早期选择和进一步试验材料。

30 Jatropha curcas provenances growth observation and fine trees primary choice were conducted in Zhanjiang,Guangdong,the results showed that the various provenances tree high,crown breadth growth,fruit quantity were very significantly different.By analysis of variance and Duncan's multiple comparison showed that the no.219,and no.222 various indicators were relatively high,as a superior provenance for early selection;taking results in number 100,height 200 cm,and the crown 200 cm as the standard,234A-2,234B-4,219A-5,220A-1,212B-3,225A-1,225A-4 and 240B-5 were selected in fine Jatropha curcas provenances as superior provenances for early selection and further test materials.
