초록

Barnyard grasses are dominant weed that arenot eliminated easily in the direct water seeding cultivation.
So, deep water treatment can reduce their growth at the earlygrowing stage of submerged paddy. This study was carriedout to investigate the reducing growth of the barnyard grassesthrough flooding at seedling stages of rice plant in the greenhouse. Under the normal condition, the plant height of ricevariety, Samgwangbyeo, and 3 species of barnyard grass,E. caudata, E. pratocola and E. utilis were not showed thedifference up to 10 days after seeding while the plant heightof 3 barnyard grass species, especially E. utilis, was moreelongated than the rice at 25 days after seeding. Plant heightof the 3 barnyard grasses were not elongated largely during3, 5 and 7 days of flooding treatment at 10 days after seeding.
Interestingly, the rice seedlings was grown over 20 cm, andthe flooding tolerance of rice seedling was higher than the3 barnyard grass varieties. However, after flooding treatmentfor 3, 5 and 7 days, the elongation of plant height of 3barnyard grasses, especially E. utilis was more speedy comparedto rice seedlings as 6 to 9 days passes. And the protein spotsfrom barnyard grasses were also reduced and eliminated morethan the spots of rice seedling after flooding treatment
