小麦条锈病是一种寄生性真菌病害,其病菌孢子借空气而传播.侵害小麦的锈病孢子,是园形的单细胞,它落在小麦叶片上,遇到适宜的温湿度条件,就生出一根芽管来,扎入叶片气孔,长出菌丝,在细胞间隙里蔓延.大约一个星期,、菌丝产生大量的新孢子,形成所谓孢子堆,颜色与铁锈相似.被锈菌侵害的小麦,生理机能失调,生长不良;锈菌孢子堆成熟时,穿破叶片表皮,向外飞散,麦叶“千疮百孔”,叶面蒸腾加剧,使小麦格外“饥渴”,抽穗扬
Wheat stripe rust is a parasitic fungal disease, the spores of the bacteria spread by the air.Excavate the wheat rust spores, is a park-shaped single cell, which falls on wheat leaves, meet the appropriate temperature and humidity conditions, to give birth to a The root germ tube comes in and plunges into the stomata of the leaf and grows mycelium and spreads in the interstitial cells.About a week, the mycelium produces a large number of new spores and forms the so-called spore heap that resembles the rust in color. , Physiological dysfunction, poor growth; rust spore reactor mature, piercing the leaf epidermis, flew outward, the wheat leaves “riddled with holes”, increased leaf surface transpiration, so that the extra “hungry” wheat, tassel Yang
