摘要
从引自浙江省林科所3个美国山核桃优良品种中筛选出马园1号、马园2号、马园4号3个优良家系,其24年生单株坚果产量分别为12 kg、4 kg、5 kg,坚果出仁率比原品种分别提高5.4%、0.7%、0.8%。3个家系核油中单不饱和脂肪酸含量分别为55.69%、55.57%、54.32%,比原品种核油中单不饱和脂肪酸含量提高9.63%、11.14%、10.69%。美国山核桃适宜湘西南生长,可作为新经济林树种发展应用。
Three superior families （Mayuan No. 1 ,No. 2 ,No. 4） were selected from three Carya illinoensis varieties cited from Zhejiang Forestry Academy, and their yields per individual nut production of 24 a were 12 kg,14 kg,15 kg. Rates of nut-out were higher than the original varieties by 5.4% ,2.7% ,0.8%. Monou-nsaturated fatty acid in oil from of three families were 55.69% ,55.57% ,54.32%, which were higher than the original varieties by 9.63 % ,11.14 %, 10.69 %.
