引种植物赤苞花的扦插繁殖研究

目的]探索赤苞花（Megaskepasma erythrochlamys）快速的无性繁殖方法。方法]选择不同年龄段的插条及基质开展赤苞花的扦插繁殖研究。结果]赤苞花属于皮部生根型植物；扦插成活率与年龄和木质化程度有一定的关系，其中1年生木质化的枝条扦插成活率最高，在珍珠砂、河沙和蛭石中的扦插成活率分别为73％、87％、54％，带嫩叶枝插条成活率最低，在珍珠砂、河沙和蛭石中的扦插成活率分别为25％、46％、33％。赤苞花对基质有一定选择性，采用河沙作基质为最佳。结论]该研究可为赤苞花进一步无性繁殖研究奠定基础。

Study on Cuttage Propagation of Megaskepasma erythrochlamys,An Introduced Horticulture Plant

Objective ] The aim was to explore the rapid asexual reproduction method of Megaskepasma erythrochlamys. Method ] The cut- tage propagation research of Megaskepasma erythrochlamys was conducted on by choosing different year-old cuttage grafting and different media. Result] Megazkepasma erythrochlamys is capable of rooting from the stem cortex, and survival rate of the cuttings has certain related to degree of cuttage lignifieation. The lignified cuttings from one-year-old branches have the highest rate of survival, is 73% in pearl sand, 87% in river sand, 54% in vermiculite, respectively, and those from tender branches rank the lowest, is 25% in pearl sand, 46%, in river sancl 33 % in vermiculite. Meg~kepasma erythrochlamys presents certain selectivity to growing media, and the river sand is the best growing media for the cuttings. Conclusion] The study lays a basis for future research on asexual reproduction of Megaskepasma erythrochlamys.
