| 摘 要： | 麻竹枯萎病是福建省南平麻竹生产基地一种毁灭性的新病害。经测定,抗冻性强不感染枯萎病的南平品系麻竹与抗冻性弱严重感染枯萎病的漳州品系麻竹,在水分、电导率、酶活性、蔗糖含量及pH值等均存在显著差异。这些差异阐明两个不同品系麻竹抗病性的机理;冻害是诱导枯萎病发生的主要因素,土壤中兼性寄生的半裸镰孢霉(Fusarium Semitectum)是在麻竹遭受严重冻害之后,才能从竹杆基部的节间伤口侵染为害。选用抗寒品种(品系)是防治麻竹枯萎病的根本措施。

| Abstract: | The wilt disease of Dendrocalamus latifiorus is a new disease which have been discovered in Nanping, Fujian. The difference of physiological and biochemical activity between Nanping-strain and Zhangzhou-strain of D. latifiorus had been determinend. The experiments showed that the different metabolism was a nature of disease resistance between Zanping-strain and Zhangzhou-strain; only the host came to be harmed by cold iniury, the pathogene of wilt disease C Fusa-rium Semitectum) would be able to infect the host. Therefore, the wilt disease of D. latifiorus was induced by cold injury.
The selection of cold resistance species ( strain ) is an effective method to control the wilt disease of D. latifiorus. |
