用1％、2％及3％的壳聚糖包衣大豆种子，考查了种子萌发及幼苗的一些生理特性变化。结果表明：包衣种子的发芽率及发芽势提高，其幼苗根数、根瘤数、单株于物质及叶和根中光合产物积累、叶片光合速率及可溶性蛋白质含量均有所增加，其中以1％效果最好。 Soybean seeds were coated with 1%, 2%, and 3% chitosan, and the seed germination and some physiological characteristics of seedlings were examined. The results showed that the germination rate and germination potential of the coated seeds increased. The number of seedlings, the number of nodules, the accumulation of photosynthate in the plant, the photosynthate in leaves and roots, the photosynthetic rate and soluble protein content in the leaves increased, %best effect.
