摘要
麻疯树是一种理想的进行生物燃油生产的木本油料树种。麻疯树油脂主要储存在种子中,种子油量大小由种子粒重和含油率构成。因此,提高麻疯树种子粒重和含油率可增加麻疯树种子产油量。研究表明,麻疯树种子粒重、含油率存在显著的表型差异,改良空间较大。相关性分析显示,麻疯树种子大小(长、宽、高)与单粒种子重表现出较高相关性(相关系数r=0.69,0.54,0.69),单粒种子重和种子含油率表现出弱的负相关性(r=-0.07),而种仁宽、高与种子含油率表现出一定正相关(r=0.47,0.54),同时种仁宽、高与种子宽、高呈显著正相关。因此,在一定程度上可通过提高种子宽、高来提高种子的单粒重和含油率,从而提高种子的产油量。
The oil produced by Jatropha curcas L seed.is currently viewed as an economical alternative biofuel with tremendous potentials.The seed oil amount depend on both seed weight and oil content.Thus the oil production could be promoted by the enhancement of the seed weight and oil content.This study showed that there was a significant phenotypic variation for the seed weight and oil content in J.Curcas.Correlation analysis showed the size of seed（length,width and height） was strong correlated to single seed weight（r=0.69,0.54,0.69）,single seed weight was weakly and negatively correlated with the seed oil content（r=-0.07）.The width and height of kernel was certain degree positively related with seed oil content（r=0.47,0.54）.The width and height of kernel were significant positive with seed＇s.Thus,the oil production could be promoted to a certain degree by improving the seed width and height,which could promote single seed weight and oil content.
