摘要
以掌叶木种子为试材,研究了在室温干藏、4℃干藏、4℃沙藏3个不同贮藏条件对种子的相对电导率、MDA含量、SOD活性及可溶性糖含量等生理生化特性的影响。结果表明:4℃干藏有利于延长掌叶木种子的贮藏寿命;4℃干藏的种子相对电导率、MDA含量和可溶糖含量均小于室温干藏、4℃沙藏的含量,而4℃干藏的SOD活性高于室温干藏、4℃沙藏的SOD活性;贮藏条件与相对电导率、MDA含量、SOD活性的相关系数均达0.5以上,可作为种子贮藏的评价指标。
Taking Handeliodendron bodinieri seeds as test materials, the effects of different storage conditions under different treatments in room temperature and dry storage, 4℃ and dry storage, 4℃ and sand storage on relative electric conductivity,MDA content,SOD activity and soluble sugar content et al of physiological and biochemical characteristics during storage of Handeliodendron bodinieri seeds were studied. The results showed that 4℃ and dry storage was favorable for extending the storage life of Handeliodendron bodinieri seeds. The relative electric conductivity, MDA and soluble sugar content of seeds in 4℃ and dry storage were tess than the content of room temperature and dry storage and 4℃ and sand storage. But the SOD activity in 4℃ and dry storage was higher than the activity of the other two treatments. The correlation coefficient among storage conditions and relative electric conductivity, MDA content and SOD activity all reached 0. 5 above. So that could be as the evaluation index of seed storage.
