| 摘 要： | 研究表明，壳聚糖除了对烟草黑胫病菌（Ｐｈｙｔｏｐｈｔｈｏｒａ ｐａｒａｓｉｔｉｃａ）有抑制作用外，还能诱导烟草植株的抗病性。烟苗经浓度为０．５ｇＬ＾－１和１ｇＬ＾－１的壳聚糖处理４ｄ后，诱导效应分别为７８．５６％和１００％，用浓度为１ｇＬ＾－１的壳聚糖处理烟草幼苗，叶片中的苯丙氨酸解氨酶（ＰＡＬ）、过氧化物酶（ＰＯ）和多酶氧化酶（ＰＰＯ）３种防御酶的活性均比ＣＫ有所提高。

| Abstract: | Chitosan, which is popular in some biosome, can inhibit the growth of haphae and entirely inhibit the budding of zoospores. It can also induce tobacco seedling resistance against Phytophora parasitica . Mass concentration of chitosan at 0.5 g L -1 and 1 g L -1 showed the induction efficiency of 78.56% and 100% after 4 d treatment, respectively. Activities of the three defense enzymes (Phhenylalanine ammonia lyase, Peroxidase and Polyphenoloxidase) in the leaves of tobacco seedling treated with chitosan at 1 g L -1 were increased more than those of controls.
