摘　　要：以青花菜(Brassica oleracea var.italica)显性细胞核雄性不育系‘DGMS8554’和细胞质雄性不育系‘CMS8554’为试材,研究不同整枝方式对两类不育系留种植株开花结实特性的影响。结果表明:‘DGMS8554’的显球、开花和结荚时间较‘CMS8554’分别早4~5 d、3~4 d和3~6 d,授粉后7~9 d显荚,从结荚到种子褐变45~47 d,由褐变到收获9~11 d;‘DGMS8554’和‘CMS8554’的最佳处理方式分别为主花球上留3个侧球和4个侧球。‘DGMS8554’去除主花球后产生的侧花球能正常开花结实,花期较不去主花球植株晚10~14 d,种子收获期晚10~13 d,显球7 d后去除主花球的种株的单株产籽量和发芽率最大,分别为8.11 g和97.32%,为最优处理;‘CMS8554’去除主花球后产生的侧枝不能正常开花结实。The effect of different pruning methods on flowering and fruiting characteristics with test materials of broccoli Dominant Genic Male Sterile lines of‘DGMS8554'and Cytoplasmic Male Sterile lines of‘CMS8554'seed plants were studied. Results showed that the time of appearing bouquet,flowering,podding and harvest of‘DGMS8554'line was 4–5 days,3–4 days and 3–6 days earlier than‘CMS8554'line,respectively. It took 7–9 days from pollination to podding,about 45–47 days from podding to browning and 9–11 days from browning to harvest. The optimal treatments of‘DGMS8554'and‘CMS8554'were at 3 lateral balls and 4 lateral balls of the main bouquet,respectively. After cutting the main bouquet,plant‘DGMS8554'can flower and fruit,while‘CMS8554'can not. Flowering and harvesting time of‘DGMS8554'was 10–14 days and 10–13 days later than rest of the main bouquet. when cutting the main bouquet after appearing ball 7 days later,the grains yield per plant and germination rate were maximum,8.11 g and 97.32%,respectively. This method was the optimal treatment.
