Abstract
To characterize active cells during microspore culture of Angelica gigas, flow cytometric and epifluorescent techniques were applied. The knowledge obtained from these types of studies will give us insight into early stage in plant development and may lead to the application of microspore-derived from haploid plants for breeding in recalcitrant species. Viability of cultured microspore differed depending on the developmental stages. Frequencies of active cells from tetrad, uni-nucleate, bi-nucleate and matured pollen were 12.8, 49.3, 42.3 and 31.7%, respectively. Alive microspores have luminescent the green fluorescence stained with FDA and blue fluorescence stained with DAPI.
당귀 반수체 육성의 기초차료를 얻고자 배양 소포자의 활력과 특성을 Flow cytometry로 관찰한 바 그 결과를 요약하면 다음과 같다. 1. 소포자 활력은 발육 시기에 따라 차이를 보여 배양 4일경에 4분자기 12.8%, 1핵성소포자기 49.3%, 2핵성소포자기 42.3% 및 성숙화분은 56.4%였다. 그리고 배양 20일 경에 는 소포자의 활력이 감소하여 배양중 배지개선과 계대배양이 요구됨을 알 수 있었다. 2. 발육시기에 따라 소포자 구조 peak가 다르게 조사되어 4 분자기는 원형을 보이다가
