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。
In Zhanjiang City, Guangdong Province, 30 provenances of Jatropha curcas were observed for growth and primary tree trials were conducted. The results showed that there was a significant difference in tree height, crown growth and the number of results among all provenances. The multiple comparisons of variance analysis and Duncan method showed that the indexes 219 and 222 were relatively high and could be used as the best provenances for early selection. The results were as follows: number of plants per plant (-1), tree height of 200 cm and crown width of 200 cm , Excellent individuals 234A-2,234B-4,219A-5,220A-1,212B-3,225A-1,225A-4,240B-5 were selected from 30 provenances of Jatropha Germplasm for early selection and further testing of materials.
