几种景天科植物扦插繁殖研究

以德国景天、勘察加景天、‘胭脂红’景天、紫茎八宝、垂盆草及金叶佛甲草为试材,对其扦插生根时间、成活率、生长速率、越夏性、枯黄期及返青期进行研究。结果表明:垂盆草生根最快且分枝数最多,紫茎八宝生根最慢且分枝数最少;几种材料扦插成活率没有差异,均为100%;‘胭脂红’景天越夏有不适反应,德国景天、勘察加景天、紫茎八宝、垂盆草及金叶佛甲草均能安全越夏;‘胭脂红’景天枯黄期晚返青早、金叶佛甲草不越冬。

Research on Cutting Propagation of Several Crassulaceae Plants

Using Sedum bybridum cv.Immeryrunchett,Sedum kamtschaticum,Sedum spurium ’Coccineum’,Hylotelephium erythrostictum,Sedum sarmentosum and Sedum lineare as material,the rooting time,survival rate,growth rate,oversummering,yellow period and turning green period were studied.The results showed that Sedum sarmentosum had fastest rooting time and largest number of branches but Hylotelephium erythrostictum had slowest rooting time and smallest number of branches.The survival rate was 100% that was no significant difference among the several crassulaceae plants.Sedum bybridum cv.Immeryrunchett,Sedum kamtschaticum,Hylotelephium erythrostictum,Sedum sarmentosum and Sedum lineare were oversummering except Sedum spurium ’Coccineum’.Sedum spurium ’Coccineum’ had latest yellow period and first turning green period but Sedum lineare was no overwintering.
