稻粒变色(有些国家也称为脏大米或霉大米)在阿萨姆邦急剧增多,特别是在中等肥料种植下高产的含盐的作物中如此(7月——12月)。稻粒变色减少(或降低)出芽率,引起胚鞘或胚根腐烂,或两者兼有,其结果形成空壳和减少产量。在阿萨姆邦对贮藏的稻粒的标样检验表明:有22种真菌约与93％有斑点的谷粒有关联。细菌和两种线虫(既不是稻茎线虫(Ditylenchus angustus)也不是稻干尖线虫(Aphelenchoides besseyi)从现存的变色稻粒中分离出来。最普通的真菌——弯孢菌(Curvularia Lunata)同37％变色的稻粒有关系;镰
Discoloration of rice grains (also known as dirty or mildewed rice in some countries) has been rapidly increasing in Assam, especially in high-yielding salinity crops under medium-fertilizer cultivation (July-December). Discoloration of rice grains reduces (or reduces) budding rates, causes decay of the embryogenic sheath or radicle, or both, resulting in an empty shell and reduced yield. Standard tests on stored rice grains in Assam showed that 22 species of fungi were associated with about 93% of the speckled grains. Bacteria and two species of nematodes, neither Ditylenchus angustus nor Aphelenchoides besseyi, are isolated from existing discoloration-tolerant rice grains.The most common fungus, Curvularia Lunata, % Discoloration of rice has a relationship; sickle
