Abstract
The longer pollen stage grew to flowering stage, the higher anther respiratory rate in vivo became. and it was rapidly increased just before flowering. The anther respiratory rate in vitro showed the first and second peak points after 3-7 days and 9-1l days in culture, respectively, and fastest and highest in Daecheongbyeo with high sporophytic potentiality. It was lower in cold-pretreatment than non-treatment at the early days, but higher from 15 days after culture. The frequency of browning anthers was promoted by cold-pretreatment. The respiratory rate was not different between uncolored and browned anthers at 12 days, but it was higher in browned anthers after 24 days in culture.
벼 약배양에 있어서 배양약의 viability의 변화를 관찰하고자 밀양 2003, 대청벼, 치악벼를 재료로 품종 및 저온전처리, 약의 갈변에 따른 호흡율의 변화를 2~3일 간격으로 조사하였다. 화분의 발육시기에 따른 배양전 약의 호흡활성은 개화직전에 가장 높았으며, 배양적기인 stage 3~4에서의 호흡율은 12.46
