摘要

稻瘟病是稻瘟菌引起的水稻最常见病害之一。稻瘟病是水稻生产国的经常性问题,严重降低了水稻产量。稻瘟病菌菌丝的生长和产孢受多种因素的影响,如湿度、温度、营养物质的有效性等。与其他真菌一样,米曲霉也需要非常少量的营养物质来维持其生理和代谢活动。通过调节这些微量营养元素或微量元素,可以控制稻瘟病菌的生长和孢子的产生。本文研究了锌(Zn)、硼(B)、镁(Mg)和铜(Cu)四种微量元素对稻瘟病菌生长和产孢的影响。在2 ppm(百万分之一)浓度下,锌、硼和铜对生长和产孢最有效,当培养基中这些元素的浓度增加时,生长和产孢量减少,而在缺乏镁的情况下,生长和产孢量减少。最佳生长需要微量的镁,即2 ppm。之后,镁浓度的增加并不显著。

Effect of trace elements Zn, B, Mg and Cu on the growth and sporulation of Pyricularia oryzae, the causal organism of blast disease of rice
Blast is one of the most common disease of the Rice crop caused by Pyricularia oryzae. Blast of Rice is a recurrent problem of Rice producing countries declines productivity drastically. Mycelium growth and sporulation of P. oryzae is depend upon many factors i.e. humidity, temperature, availability of nutrients etc. Like other fungi P. oryzae also requires some nutrients in very minute quantity for their physiological and metabolic activities. Regulating these micronutrients or trace elements we can control the growth and spore production in P. oryzae. In this paper, we studied effect of four trace elements i.e. Zinc (Zn), Boron (B), Magnesium (Mg) and Copper (Cu) on growth and sporulation of P. oryzae. Zinc, Boron and Copper are most effective and promote growth and sporulation at 2 ppm (parts per million) concentration when we increased concentration of these elements in the medium, growth and sporulation decreased .On the other hand less growth and sporulation reported in the absence of Magnesium. Minute quantity of Magnesium is required for optimum growth i.e. 2 ppm. after this increasing concentration of Magnesium is not significant.
