摘要
采用越光、佐贺18、日本晴、日光4个品种田间发病分级和MA-30A测食味的方法,研究水稻纹枯病对稻米品质及产量的影响。结果表明:纹枯病危害使稻米蛋白质、直链淀粉含量增加;谷粒厚度、宽度减小,成熟度降低,千粒重下降;粘度、味度值降低。从而导致产量和品质下降。
The experiment was conducted to investigate effects of sheath blight on rice quality and yield. The results indicate that the injure of rice sheath blight increases the protein and amylase contents, decreases grain thickness and width, reduces grain maturity degree and 1000-grain weight and lowers the stick and taste degree, which results in decrease of rice yield and grain quality.
