本研究主要采用水培的方法,研究了纹枯病菌接种,对水稻感、抗病品种纹枯病抗性以及抗病相关酶活性的变化的影响.结果表明,抗病品种ZH5接种纹枯病菌后,初期引起植株体内过氧化氢(H2O2)含量迅速上升并抑制过氧化氢酶(CAT)的活性;在接种48h后显著提高了植株体内脂氧合酶(LOX)的活性;接种后的丙二醛也显著提高;可溶性酚的含量比接种前要高,并且可溶性酚的含量跟植物的抗病性有一定的正比关系;但木质素含量在下降;在接种后加快了活性氧代谢,使多酚氧化酶(PPO)活性加速上升,在36h达到顶峰;接种后的过氧化物酶(POD)活性也有所上升.感病品种lemont相关酶活性在接种前跟抗病品种ZH5差别不是很大,但是接种后就大不一样了,接种后的感病品种活性氧的代谢要比抗病品种要快的多;致使其丙二醛(MDA)含量加速增长;木质素跟可溶性酚的含量减少的也要比抗病品种要多;脂氧合酶(LOX)的活性在48h达到顶峰;接种时间过长后氧化酶活性也迅速降低,使植物抵抗病原物的能力下降,从而加快了植物的死亡.

关键词:水稻、纹枯病菌、抗病相关酶、可溶性酚、木质素
This research mainly adopts the eppendorf tube method, WenKuBing bacteria vaccination, sense of rice varieties WenKuBing resistance, disease resistance and resistance related enzymes change. The results show that WenKuBing bacteria resistant varieties ZH5 after inoculation, the initial cause plant body hydrogen peroxide (H2O2) content rising rapidly and inhibit catalase (CAT) activities; 48 h after inoculation remarkably enhance the plant body lipoxygenase (LOX) activity; After inoculation of malondialdehyde also increased significantly; The content of soluble phenol than before vaccination is high, and the content of soluble phenol with plant disease have certain proportional is; But the lignin in down; After inoculation to speed up the active oxygen metabolism, make the polyphenol oxidase (PPO) accelerated activity, in 36 h peak; After inoculation of peroxidase (POD) activity has also increased. Susceptible cultivars lemont related enzymes activity in before inoculation with resistant varieties ZH5 difference is not very big, but after inoculation is great different, inoculation of susceptible cultivars of active oxygen metabolism than resistant varieties to much faster; If the malondialdehyde (MDA) content accelerating; With the content of soluble phenolic lignin reduced than resistant varieties to many; Lipoxygenase (LOX) activity in 48 h peak; Inoculation after long time oxidase activity quickly down, the plants resist pathogens ability, thus speeding up the plant's death.
再问: 非常感谢这位朋友的热心帮助,有没有地方需要修改吗?不需要的话我就 直接把这个弄到我的毕业论文里了
