Pre-harvest sprouting (PHS) refers to seed germination during ripening, due to loss of dormancy before harvest. As PHS in rice causes decrease in grain yield and quality, tolerance to PHS is an important trait of Japonica cultivars in Korea. It is important to investigate the related genes and envir...

벼의 수발아가 발생하는 시기는 언제인가? | 수발아는 종자가 발아력을 갖추기 시작한 이후에 휴면성이 약해지면서 이삭에서 발아하는 현상을 말한다. 벼의 수발아는 등숙 단계로 보면 대체로 황숙기 이후 발생하기 시작한다(Park & Park, 1984). 수발아성은 종자의 휴면정도와 관련이 높기 때문에 생태형 및 품종간 차이가 크게 나타나는데 자포니카형 품종이 인디카형 및 통일형보다 수발아가 잘되며(Lee et al. | |
수발아란 무엇인가? | 수발아는 종자가 발아력을 갖추기 시작한 이후에 휴면성이 약해지면서 이삭에서 발아하는 현상을 말한다. 벼의 수발아는 등숙 단계로 보면 대체로 황숙기 이후 발생하기 시작한다(Park & Park, 1984). | |
벼 품종별 수발아 발생률은 어떻게 나타나는가? | 1. 벼 품종별 수발아율은 품종 간에 크게 차이가 났으며, 다산벼, 조운벼, 남평벼가 내수발아성이 강하였고, 고품벼와 조평벼는 수발아성이 높게 나타났다. 2. |
