摘要：随着能源需求持续增长和国际原油价格的不断攀升,发展可再生生物质能源已成为各国的共识[1]。生物燃料乙醇作为汽油的第1代替代品,广受世界关注[2]。近年来该行业迅速崛起,并掀起了以甘蔗、玉米、小麦等为原料生产燃料乙醇的工业化热潮;由此引发粮食短缺,对世界粮食安全产生了很大影响。特别是在中国耕地资源紧缺,粮食供求处于紧平衡,以玉米为原料的发展空间受到了极大的限制,为保证粮食安全,生物燃料乙醇原料多元化势在必行[3]。
The study aims at compare and analyze the variation pattern of the phenotype characters and starch content of Quercus mongolica seed of different provenances.The length,width,length / width ratio,single kernel weight of Q.mongolica seeds from 16 natural distribution regions in China were measured and analyzed.The results showed that there were extremely significant differences among seeds from different region in seed characters.The length and width of seeds ranged from 14.76 mm to 21.08 mm and from 11.87 mm to 15.31 mm,respectively.The length / width ratio of seeds ranged from 1.21 to 1.49.The single kernel weight ranged from 0.60 g to 1.78 g and the contents of starch ranged from 4.42 g.kg-1 to 5.48 g.kg-1.The length of seeds has a extremely significant positive correlation with the width and weight of seed,and the width of seed had a significant positive correlation with the weight of seed.The seed width has a significant positive correlation with contents of starch.The width of seeds had a significant negative correlation with altitude,and had a positive correlation with July’s mean temperature.The weight of seed had a significant positive correlation with July＇s mean temperature too.The correlation of the other phenotypic character and starch content of Q.mongolica seed to geographical climate factors was not significant.According to the results of cluster analysis,sixteen Q.mongolica provenances could be divided into three groups with big fruit and high starch content,middle fruit and starch content,small fruit and low starch content,in which the provenances from Dailing of Heilongjiang Province,Benxi of Liaoning Province and Dayangshu of Inner Mongolia were the superior provenances.
