Effects of Flooding Treatment on Physiological Characteristics of Rice Cultivars
수도 관수처리에 의한 생리적 특성의 품종간 차이
Abstract
To clarify the varietal differences of resistance to complete flooding, physiological characteristics in relation to flooding resistance in each growth stage of rice plants, the present study was carried out. The rate of survival after flooding at seeding stage of rice plants of the cultivar 'FR 13A' and Ind. X Jap. cultivars were 91.8% and 33.8% to 40%, respectively, while the Japonica varieties were completely dead. The tolerant varieties which has higher rate of survival showed the higher
통일형품종과 일본형품종간의 침관수저항성 차이를 명확히 하고자 유묘기, 분얼성기 및 수잉기에 각각 관수처리하여 관수저항성과 관계한 생리 화학적 특성을 검토한 결과는 다음과 같다. 1. 유묘기 관수처리로 묘생존율은 'FR13A'가 91.8%, 통일형품종들이 33.8~40% 인데 비하여 일본형품종들은 완전 고사하였으며 묘생존율이 높은 품종 일수록 관수중
