자웅동주 단성화인 오미자의 화아형성 및 성 결정 시기를 밝혀 기초연구의 토대를 마련하고, 전정을 통해 암꽃 착생량을 증가시키고자 수행하였던 시험결과는 다음과 같다 1. 오미자의 화아 형성은 6월 상순에 시작되었으며 7월 상순 완료되었다. 2. 익년 결실지와 동아는 9월 성장이 완료되었다. 3. 전정구의 2차 생장지 발생은 34-56%로 높았으나 7월1일 10절 처리는 25%로 낮았다. 4. 전정된 가지들의 개화비율은 $13{sim}31.3%$로 무처리 가지의 개화비율 36.7%보다 낮았고 가지별 암꽃 착생량도 무처리보다 적은 경향이어서 전정에 의한 암꽃착생 증진 효과는 없었다.
The purpose of this experiment is to improve the ratio of female flower in Schizandra chinensis Baillon. The experiment was carried out in two purposes. One was to understand the development stages on bud formation and determining sex after bud formation by stage. The other was to investigate characteristics of flowers forming on spring when summer pruning was taken place in different cutting part and timing in S. chinensis Baillon. The outcome was that on 7th of June the flower bud was found next to leaf primordium in branch of this year and no changes were found in shape for two weeks by 26th July. On 26th of June, an ovule that forms organ was observed and then, an ovule was found after sex was determined on 6th of July. Second experiment was carried out to find out when the sex was determined by adapting different pruning methods; cutting the branch at 6th node on June 1, June 15, and July 1; cutting the branch at 10th node on June 15, and July 1. The result was that the re-growth ratio on the branch 6th node was cut on June 1 and June 15. July 1 was 34-56% and, however, the number of setting flowers and mail flowers were fewer than the normal branches. More over, even though the re-growth ratio of branches were 34-25% when the cutting was taken place at 10th node on June 15 and July 1, the number of setting flowers and mail flowers were the same as the non treated branch. As a result, it is assumed that cutting controlling in this plant to increase the number of female flowers has no effect.
