马尾松(Pinus massoniana Lamb.)是我国南方造林用种量最多的树种,种子检验任务相当繁重。探索马尾松种子快速准确的检验方法具有重要的实践意义。M.Simak和S.K.Kamra分别研究过欧洲赤松(Pinus sylvestris L.)和挪威云杉(Picea abies Karst.)种子的x射线衬比法,认为x射线衬比法优于四唑法和靛蓝法。x射线衬比法的根据是细胞膜
Pinus massoniana Lamb (Pinus massoniana Lamb.) Is the species most used in afforestation in southern China, and the task of seed testing is rather heavy. It is of important practical significance to explore the rapid and accurate test method of masson pine seed. M.Simak and S.K. Kamra studied the x-ray contrast method of the seeds of Pinus sylvestris L. and Norway’s Picea abies Karst. Respectively. The x-ray contrast method is superior to tetrazolium method and indigo method. The basis of the x-ray contrast method is the cell membrane
