采用人工加速老化方法研究了香椿种子衰老与膜脂过氧化作用的关系。结果表明：随着种子老化程度的增加，产生速率增快，MDA含量增高，膜透性增大。人工老化处理5d的香椿种子，其MDA含量、相对电导率及产生速率分别较对照种子高96．20％，45．56％和353．49％香椿种子活力与膜脂过氧化程度呈显著的负相关。这表明膜脂过氧化可能是导致香椿种子衰老的主要原因之一。
Artificial accelerated aging method was used to study the relationship between senescence and membrane lipid peroxidation in Toona sinensis seeds. The results showed that with the increase of seed aging, the rate of production increased, MDA content increased, and membrane permeability increased. Artemisia tomentosa seeds treated with artificial aging for 5 days had significantly lower MDA content, relative electrical conductivity and higher production rate than 96.20%, 45.56% and 353.49% of the control seeds, respectively, and significantly decreased the membrane lipid peroxidation Related. This indicates that membrane lipid peroxidation may be one of the major causes of aging of Toona sinensis seeds.
