| Abstract: | The in vitro cuttings of F1 hybrid of yellow-flower broccoli (Brassica oleracea L. var. italica Phenck) were used as the materials for the studies of proliferation, rooting, and transplanting of micropropagation in broccoli. The results showed that the best medium for proliferation was MS with 0. 2 mg·L~(-1) BA and 0. 01 mg·L~(-1) NAA， the mean coefficient of proliferation was 2. 95, the quality of seedling grade was 1. 67; the appropriate rooting induction medium was 1/2MS with 0. 2 mg·L~(-1) IBA, the rooting rate reached 94. 45%, and the quality of seedling grade was 3. 00. In the well-growth plantlets, the average plantlet height was between 4 and 5 cm, the average root number was between 4 and 5, and the average root length was between 2 and 3 cm. When the plantlets were transferred into the mixed media (peaty soil, vermiculite and sand), and the survival rate was up to 83. 33%. |
