摘要
报道了我国樟科（Lauraceae）5属9种植物核型研究结果，其中7种染色体数目为首次报道。核型结果为：樟（Cinnamoumcamphora）20m＋4sm；油樟（Cinnamoumlongepaniculatum）20m十4sm；黑亮楠（Linderamegaphylla）18m（2SAT）＋6sm；山苍子（Linderacubeba）16m＋8sm；香叶树（Linderacommunis）22m＋2sm；川钓樟（Linderapulcherrima）20m＋2sm＋2st（SAT）；红果黄肉楠（Actinodaphnecuplaris）22m+2sm；楠木（Phoebezhennana）18m＋6sm（4SAT）；赛楠（Nothaphoebecavaleriei）24m。樟科属间核型差异显著，研究的5个属有1A、2A、1B、2B4种类型，1B核型在植物中少见报道。
The chromosome numbers and karyotypes of 9 species of 5 genera of ChineseLauraceae plants were reported. Seven species of these were first reported on their chromosome numbers. The results of karyotype analysis are:Cinnamoum camphora 20 m +4 sin; C. longepaniculatum 20 m + 4 sin 3 Lindera megaphylla 18 m (2SAT) + 6 sin; L.cubeba 16 m+8 sin;L. communis 22 m+2 sin IL. pulcherrima 20 m+ 2 sin+2 st(SAT) 1Actinodaphne cuplaris 22m +2 sin; Phoebe zhennana 18 m + 6 sin (4SAT ) i Nothaphoebe cavaleriei 24 m. There were distinct differences between genera of . Lauraceae plants in their karyotypes. Four types, lA, ZA, IB, ZB, were found in five genera. IB karyotype is rarely reported in plant.
