木兰科植物无性繁殖研究概况

概述了近年来木兰科植物无性繁殖的研究进展．木兰科植物中，鹅掌楸、紫玉兰及含笑属中的一些种扦插已获成功，但该科中的常绿树种生根率普遍低于落叶树种；嫁接技术相对较为成熟；组织培养较为薄弱，只见凹叶厚朴和鹅掌楸有组培成功的报道．

The Review of the Asexual Propagation on Magnoliaceae

The Magnoliaceae plants are excellent afforesting tree species, which have broad perspectives of exploitation and utilization in industrial wood ,city's amenity afforestation ,perfume and medicinal material industry .It is necessary to pay more attention to the exploitation and protection of Magnoliaceae plants. The survey of the study about the Magnoliceae plants'asexual reproduction has been introduced in this paper .According to a series of successful trials ,the authors indicate that high rooting rate can be gotten among Liriodendron chinese,Magoolia liliflora and some tree species belonging to Michelia and the rooting rate of evergreen species are superior to the deciduous species . Compared with others , grafting has been widely used as a ripe technique in practice and scientific work . The tissue cultivation is most vulnerable spot of the three links of the asexual propagation . It is reported that M.officinalis ssp.biloba and Liriodendron chinese have been successfully cultivated up to now.The conclusion can be drawn that the tissue cultivation of the Magnoliaceae is still need further developing in the future.
