黑龙江不同种源(产地)山杏苗期对环境适应性分析

Environmental Adaptability of Armeniaca sibirica Seedlings in Different Provenances(Place of Origin) in Heilongjiang Province

收集黑龙江省不同地区的12个种源的山杏种子在齐齐哈尔进行播种试验,以研究山杏苗期对环境的适应性。结果表明:12个种源山杏的平均苗高为56.01 cm,平均地径为0.44 cm。万人欢种源的隶属函数的平均值最大,为0.55,适应性最好;讷河种源的隶属函数平均值最小,为0.41,适应性最差。选择万人欢、扎旗、龙江、七台河4个种源为优良种源,其中龙江19号隶属函数平均值最大,为0.65;七台河5号、万人欢6号、扎旗7号隶属函数平均值均为0.61;龙江山杏隶属函数平均为0.58。初步认定龙江19号在本地的适应性最好。

Armeniaca sibirica seeds were collected from 12 provenances in different regions of Heilongjiang Province for planting in Qiqihar. A comprehensive evaluation of each group was conducted by using the membership function method in fuzzy mathematics. Result shows that the average seedling height of 12 provenances is 56. 01 cm and the average diameter is 0. 44 cm. The average value of the membership function of the seedlings in Wanrenhuan Forest Farm is the largest,being 0. 55,with the optimal adaptability;the mean value of the membership function of the Nehe provenance is the smallest,being 0. 41,with the least adaptability. The four provenances of A. sibirica ‘Wanrenhuan ＇,A. sibirica‘Zhaqi＇,A. sibirica‘Longjiang＇and A. sibirica‘Qitaihe＇were selected as excellent provenances. Among them,the average value of the member function of A. sibirica ‘Longjiang No. 19 ＇is 0. 65;the average value of the membership function of A. sibirica‘Qitaihe No. 5＇,A. sibirica‘Wanrenhuan No. 6＇,A. sibirica‘Zhaqi No. 7＇is 0. 61;the average function of Longjiang sweet-apricot is 0. 58. It is initially determined that A. sibirica ‘Longjiang No. 19＇has the optimal adaptability.
