영문 초록

Riptortus clavatus, one of the many insects in major crops, damages pods and seeds, which reduces seed vigor and viability in soybeans. This study was conducted to examine the effect of diversely damaged seeds by R. clavatus on seed germination and seedling emergence and to determine the association of damaged seed with quality and yield of soybean sprouts. All seeds damaged by R. clavatus significantly (P<0.05) reduced seed vigor as measured by the rates of seed germination, germination speed, and seedling emergence. Mean seed germination rate of non-damaged seeds in sprout-soybean varieties was 97.8%, whereas the rates of seeds damaged at different levels, 31-50% and 51-80%, were 23.0 and 5.4%, respectively. The rates of seedling rot and abnormal, incomplete germination significantly (P<0.05) increased as the amount of seeds damaged by R. clavatus increased to 5, 10 and 15% against the total seeds for sprout production. Yield of soybean sprouts from seeds damaged at different levels decreased up to 13% as compared to that in normal seeds. In customer preferences on soybean sprout produce, 84% of customers participated in survey preferred to purchase sprouts from seeds with 5% of damaged seeds, but sprouts produced from seeds with 15% of damaged seeds were intended to purchase only by 22% of the customers. Areas of the seed damaged by R. clavatus were readily infected by pathogens as the seed germinated, resulted in deteriorated quality and reduced yield of sprout produce.
