| 摘 要： | 对门头沟区的19个推广核桃(Juglans regia L.)品种进行单果重、单仁重、出仁率、含油率及脂肪酸组分含量的相关测定,结果表明:供试品种间的含油率性状差异达到极显著水平,综合看来,绿波、西洛2号、礼品1号(基地)3个品种产油性能最好,含油率分别达到75.40%、72.72%、72.52%.同时,绿波以及辽核3号的亚麻酸含量最高,分别为12.80%和12.76%;西洛2号、礼品1号(基地)的棕榈酸含量最高,分别达10.84%、10.79%.另外,油酸含量最高的是中林6号(20.40%)、鲁光(19.82%);硬脂酸含量最高的是中林6号(5.32%)、礼品1号(基地)(4.78%);亚油酸含量差异不大.研究结果可为高油专用型品种核桃园的建立提供依据.

| Abstract: | Through systematic analysis of the nut weight,kernel weight,kernel rate,oil percentage and fatty acid composition of 19 walnut cultivars in Mentougou District of Beijing,we concluded that there exists distinct difference in the oil yield of these cultivars,and the general results indicated that Lvbo,Xiluo 2# and Lipin 1# showed the best performance in producing oil,with the oil percentage of 75.40%,72.72% and 72.52% respectively.Besides,Lvbo and Liaohe 3# were excellent at alpha-linolenic acid percentage,with the percentage of 12.80% and 12.76% respectively,and Xiluo 2# and Lipin 1# were excellent at palm acid percentage,with the percentage of 10.84% and 10.79% respectively.As for other fatty acids,Zhonglin 6# and Luguang had the highest oleic acid percentage,which were 20.40% and 19.82% respectively.Zhonglin 6# and Lipin 1# had the highest stearic acid percentage,which reached 5.32% and 4.78% respectively.There seemed to be no significant difference in the linoleic acid percentage of all cultivars.The fruits of this study may be favorable on the construction of high-oil walnut orchards. |
