几种景天属植物引种及其扦插繁殖研究

Research on Introduction and Cutting Propagation of Several Sedum L.Plants

笔者引进八宝景天、松塔景天、六棱景天、红毯景天、胭脂红景天、佛甲草、德景天和垂盆草8种景天属植物,通过多年引种栽培,筛选出佛甲草、垂盆草、八宝景天和德景天适宜在武汉地区栽培,其共同特点是抗性强、耐修剪、株型美观,通过佛甲草、垂盆草和德景天的扦插繁殖研究表明其扦插繁殖容易,对基质没有严格要求,露地全光照条件下扦插成活率可达100%。

Eight Sedum L. plants such as Sedum spectabile Boreau, Sedum Nicaeense All., Sedum sexangulare, Sedum album ‘Roseum’, Sedum spurium ‘Coccineum＇, Sedum lineare Thunb., Sedum bybridum cv. Im--meryrunchett and Sedum sarmentosum Bunge have been introduced in the institute. Four Sedum L. plants have been selected for cultivation in Wuhan after years of introduction and cultivation, which are Sedum lineare , Sedum sarmentosum , Sedum spectabile Boreau and Sedum bybridum cv. Im- meryrunchett. These species are featured with strong resistance, beautiful type and pruning resistance. The results showed that Sedum lineare Thunb., Sedum sarmentosum Bunge and Sedum bybridum cv. Im--meryrunchett adapt to cutting propagation, with large survived rate not requiring rigorous soil and illumination.
