| 摘 要： | 苗木形态、生理和活力状况是评价苗木质量的主要方面(刘勇,1999),苗木活力与成活率直接相关(Krameretal.,1979;喻方圆等,2002)。苗木起苗后经过分级、包装、贮藏和长途运输,到最终被栽植,这期间可能会受到失水、高温和低温、光照不足等异常因素的影响,导致苗木活力下降,从而直接影响移栽成活率。一些研究表明,失水是导致苗木活

| Abstract: | Larix olgensis seedlings were exposed to the air-drying treatments during the transplanting process. The relative moisture content, water potential, root vigor and seedling performance after transplantation were measured. The relationships among these indicators were discussed. The results showed that the seedling vigor of Larix olgensis seedling was related closely with its seedling moisture condition. The relative moisture content, water potential and root vigor were decreased gradually with the air-dryin... |
