In China, Toona ciliata and Toona ciliata var.pubescens distribute sporadically with small population size but with great development potential. Plus selection on phenotype of Toona ciliata and Toona ciliata var.pubescens, molecular genetic marker of Toona ciliata var. pubescens, research progress in physiology and ecology of Toona ciliata and Toona ciliata var.pubescens were summarized in this paper. Suggestions and prospect forecast were proposed for relative research and utilization.展开更多

In China, Toona ciliata and Toona ciliata var. pubescens distribute sporadical y with smal popuIation size but have huge deveIopment potential. The paper reviewed the research progress of their seedIing breeding, nutrient characteristics, fertiIization technoIogy, afforestation design, timber utiIization, chemistry and pharmacoIogy, and then Iooked into the future research and utiIization of Toona ciliata and Toona ciliata var. pubescens.展开更多
以1/2Hoagland营养液为基础培养液,研究了在0.1%、0.2%、0.4%和0.6% NaCl胁迫条件下,毛红椿[Toona ciliata Roem. var. pubescens （Franch.） Hand.-Mazz.]和水松[Glyptostrobus pensilis （Staunt. ex D. Don） K.

Koch]的种子萌发和幼苗生长情况.结果表明,随着NaCl浓度的增加,2个树种的种子萌发率和简化苗木活力指数均明显下降,在0.1%、0.2%、0.4%和0.6% NaCl胁迫条件下, 毛红椿和水松种子的最终萌发率分别为89.3%、87.3%、62.7%、32.0%和26.0%、16.7%、6.0%、3.3%,简化苗木活力指数分别为1.39～0.08和1.52～0.07,且毛红椿的种子萌发率和简化苗木活力指数均明显高于水松.萌发恢复实验结果表明,高浓度NaCl处理后的种子具有较高的萌发恢复率.根据实验结果初步判定毛红椿种子具有较强的耐盐性.展开更多
