Rooting Anatomical Characteristics and the Hormonal Regulation of Dendrocalamus latiflorus Cutting
摘要
Abstract
The semi-hardwood stems of Dendrocalamus latiflorus were collected and treated with different concentrations of NAA, and morphological and anatomical features of adventitious roots were observed with paraffin method. Results showed that callus was active from 20 to 40 day and from 55 to 60 day after cuttage, and the rooting rate began to decline and the spike was perishable after 60 day. The peak of root elongation was from 40 to 60 day. From 30 to 50 day and from 55 to 70 day were two peaks for root number increasing. Paren-chyma cells in the vascular cambium were the origin of adventitious root. NAA treatment could significantly im-prove the rooting rate,and cut down the time of callus formation. The differences of cutting rate,root num-ber,root index and root effect index of different concentration treatments were extremely significant,and the differences of rooting rate,rot rate and root length were significant. The best effect of cutting was the treatment with NAA of 80 mg/L.关键词
