Physiological Characteristics and Diural Changes of Photosynthesis in Japonica and Tongil Type Rice
초록
우리나라에서 육성 보급하고 있는 대표품종으로 Japonica
To elucidate the physiological characteristics of 2 japonica type and 2 tongil type of rice cultivars, photosynthesis, respiration and diurnal changes of photosynthesis rate had been investigated 6 times at each growing stage. The ratios of photosynthetic part of tongil types were higher than those of japonica types at tillering stage. The highest photosynthetic activity was measured on August 1, before heading in each growing stage, and efficiency of photosynthesis showed its the highest on July 25. Diurnal photosynthetic curve at heading stage reached the peak at 11-12 AM, but after 2 weeks from heading stage, the peak apperred at 1-2 PM. Conversion of respiration into photosynthesis for
