| 摘 要： | 目的]为绒毛白蜡的抗盐性研究提供理论依据。方法]分别采用不同浓度（0（CK）、2.9、5.8、11.7、17.6、23.4、35.1 g/L）的NaCl及盐渍土壤盐浸提液（NMS）处理绒毛白蜡种子,比较不同处理种子的萌发及幼苗生长情况。结果]随盐处理浓度的升高,绒毛白蜡种子的萌发率总体呈下降趋势;绒毛白蜡种子在NMS溶液中的发芽势和发芽指数显著高于相同浓度的NaCl处理。11.7 g/LNaCl及17.6g/LNMS盐溶液中绒毛白蜡幼苗仅出现根部生长,23.4、35.1 g/L盐溶液中无幼苗生长现象。复水处理后,在盐浓度临界值范围内,绒毛白蜡种子的萌发恢复率均达到90%以上。结论]盐胁迫对绒毛白蜡种子萌发及幼苗生长均具有明显的抑制作用。

| Abstract: | Objective]The aim was to provided the theoretical basis for studying salt resistance of Fraxinus velutina Torr.Method] The seeds of F.velutina were treated by NaCl and NMS with different concn.(0(CK),2.9,5.8,11.7,17.6,23.4,35.1 g/L),and the seed germination and seedling growth situations of F.velutina in different treatments were compared.Result]With the increase of salt concn,the seed germination rate of showed decreasing trend as a whole.The germination energy and germination index of F.velutina seeds ... |
