摘要
通过小叶杨在青海省7个主要分布区种源的收集,对其进行雌、雄株扦插苗对比试验。不同种源雌、雄株苗高生长、地径生长表现出相同的规律。雌、雄株的地径生长量、苗高生长量最好的均为:祁连、乌兰。最差的为乐都。对此项工作的研究为我省小叶杨苗期种源区划提供了理论依据。
collection 7 provenance Populus pseudo - simonii distributed in Qinghai Province, their female and male plant cuttings comparison test were conducted, different provenance the male and female plant height, diameter growth show the same rules, diameter growth, seedling height growth of female, male plants the best are Qilian, Ulan, the worst for Ledu . This work provides a theoretical basis for provenance division of Populus simonii.
