摘要:
通过在安徽皖南山区和大别山区连续3年的乌桕优良单株选择,决选出合6、金4、金8、黟4和黟5等优良单株。5株单株性状优良,抗逆性强,结果枝比例、千粒重等数量指标受环境影响较小,千粒重≥153 g,全籽含油率≥43.5%,结果枝比例≥80%,均达到优良单株标准。对优树经济性状相关性进行分析,结果表明,乌桕单位冠幅产量与果序种子数、叶形指数、千粒重和结果枝比例呈正相关,全籽含油率中皮油比例和梓油比例之间呈显著负相关,在各单株中相差较大。

Abstract:
Through three years of survey, five superior individual Sapium sebiferum trees (eg. Hefei No.6, Jinzhai No.4, Jinzhai No.5, Yixian No.4 and Yixian No.5) were selected in Dabieshan mountain area and southern mountainous area in Anhui Province. All five superior individuals showed fine quality and strong stress resistance. The proportion of fruit bearing shoot,?mass of 1000-grain and other quantitative indicators of the five trees were seldom influenced by the environment factors. The economic traits were as follows: 1000-grain weight ≥153 g; the grain oil content ≥43.5%; the proportion of fruit bearing shoot≥80%. These traits met the standards of superior individual trees. The correlation among economic traits of the superior trees was analyzed. The results showed that seed production per crown was positively related to the seed number of single infructescence, leaf shape index, 1000-grain weight and the proportion of fruit bearing shoot. The oil content in the hull was negatively correlated with the oil content in the seed with a significant difference among individual trees.
Key words:  Sapium sebiferum  selection  mass of 1000 grains  proportion of fruit bearing shoot  production per tree  oil content of whole grains
