摘要
试验选用紧穗型水稻盐丰47和散穗型水稻盐粳48两个品种,研究不同等级的水稻纹枯病对两种穗型水稻产量及品质的影响。结果表明:随着纹枯病发病级别的增大,两品种水稻的实粒数、千粒重、结实率、产量都随之显著降低,加工品质受到一定的影响,外观品质显著降低。紧穗型盐丰47的千粒重和外观品质指标变化比散穗型盐粳48更敏感,对于纹枯病的胁迫受害反应更快更大。
Two rice varieties,the tight panicle type"Yanfeng-47"and the loose panicle type"Yangeng-48",were selected for the experiment to study the effects of different levels of rice sheath blight on the yield and quality of the two panicle types.The results showed that as the severity of sheath blight increased,the number of filled grains,1000-grain weight,seed setting rate and yield of both varieties decreased significantly,and the processing quality was affected to a certain extent,while the appearance quality decreased significantly.The 1000-grain weight and appearance quality indicators of the tight panicle type"Yanfeng-47"were more sensitive to the changes,and its response to the stress of sheath blight was faster and greater than that of the loose panicle type"Yangeng-48".
