摘　　要：综述了壳聚糖在调节植物生长发育和诱导植物抗病性方面所起的重要作用及其可能的作用机制。壳聚糖对植物氨同化关键酶具有明显的生理调节功能,可以提高植物同化NH4+的能力,有利于蛋白质的生物合成与积累,改善植物的营养品质及园艺性状;并能迅速激发植物的防卫反应,启动植物的防御系统,有效地提高植物的抗病性。同时通过壳聚糖结合蛋白的分离、纯化及其生化特性的研究为进一步确定壳聚糖的作用机制奠定了基础。Important effect of chitosan on regulating plant growth, eliciting plant resistance to disease and it＇s possible operating mechanism are reviewed. Chitosan shows evidence physiological effect on the key enzymes of ammonia assimilation and enhances the amination capacity in plant, which is in favor of biology synthesize and accumulation of protein. Thus, chitosan improves nutrition quality and horticulture properties of plant. Moreover, chitosan rapidly stimulates plant defense responses, then startups defensive system and elevates resistance to disease. To a further understanding of the mechanism of chitosan on plant, we have isolated and determined some biochemical properties of a chitosan-bingding protein.
