Cutting Propagation Technology of Bougainvillea spectabili in Dry-hot Valleys of Panzhihua
摘要
Abstract
Cutting propagation of Bougainvillea spectabilis was carried on in dry hot valleys of Panzhihua. The branch diameter had a positive correlation with survival rate when cutting branches had been dipped in the ABT - 1# 100 mg · L^-1 for 3 h. The survival rate was up to 88.4% when the branch diameter was more greater than 10 mm, but if less than 5 mm, the survival was rather low. Results showed that the treatment with IBA 100 mg · L^-1 could get the best effect and the survival rate coult be up to 92.8%. The effect of 3 different rooting accelerators（ ABT- l#,α -NAA,IBA） for separate using 3 concentrations obviously was more effective than the contrast.关键词
