temperature and treatment time on the germination of weedy rice. Weedy rice seeds were treated with flame at 537, 670 nd 812℃ for 0.39, 0.57 and 1.00 second, respectively, and thier germination rates were determined. The germination of weedy rice decreased when flame temperature and treatment time i

weedy rice were evaluated. Rice plants were grown in a growth chamber for 15 days under low-temperature (13/20°C day/night) and control condition (25/20°C day/night). The degree of leaf discoloration was highly significantly correlated with the SPAD value in the low-temperature plot (r = -0.708, P <

However emergence of weedy rice differ according to the year and year. It was thought to be affected by April average temperature and total precipitation. So, for effective weedy rice control and stable rice yield, it was considered that irrigation at April 15-20 to induce the emergence of weedy ric

rice weedy rice have been applied for producing PCR polymorphisms in different fungal species. URP-PCR protocol employed stringent PCR with high annealing temperature over 55˚C throughout the thermo-cycling reaction, giving high reproducibility, Under the PCR condition, Each single URP primer produc

rice cultivation, especially in the direct seeding culture. This study examined weedy rice control by a cultural method as well as chemical application. Weedy rice showed higher germination rate, 53.7%, at 10℃, compared to Hwasungbyeo, 0.7%, indicating greater germinability of weedy rice at law temp

rices have shown very similar emergence rates at various soil depths to those sown on May 1. Barnyardgrasses have also shown similar emergence rates when sown between April 3 and May 1. Like barnyardgrasses, the old strain and weedy rices apparantly posessed a greater adaptability to emerge under lo

Low temperature stress at the seedling stage of rice is an important factor causing the leaf discoloration, wilting and consequently leads to non-uniform crop maturation. In order to screen the cold tolerance elite lines efficiently, the five cold treatment conditions with different water and air te
