在星球属里,星球品种正常的棱为7～8,偶有6棱,鸾凤玉品种正常为5棱以上,而具有5棱的星球(星球与鸾凤玉第一代杂交的五棱鸾凤兜不在此列)和3棱的鸾凤玉,则是近些年来从国外引进的珍稀园艺品种,也是经过多年反复选育才培养出来的相对稳定品种。在国外出版的部分专业图书和多浆植物网站上,也有2～4棱星球、2棱鸾凤玉品种展示,但只是个别植株的棱在生长期中暂缓发育造成的,不具备遗传稳定性和完整对称的几何形态。近几年来,我和一些掌类爱好者在星球属少棱品种的养护繁育过程中,都遇到过这样的问题:具有5棱的星球和3棱的鸾凤玉在生长期里不时发生增棱的返祖现象。成年植株如此,3年以下
In the genus of the planet, the normal variety of the planet is 7 to 8, with occasional 6 edges, and the style of the jade Phoenix is more than 5 with normal, while the planet with 5 edges (the pentagram with the first generation of the planet and the jade This column) and 3 edges of jade Phoenix, is rare in recent years introduced from the horticultural varieties, but also after years of repeated breeding was cultivated out of the relatively stable species. In some published abroad professional books and multi-plant sites, but also 2 ~ 4 edge planet, 2 edge 鸾 Feng Yu varieties show, but only the edges of individual plants suspended in the growth period caused by the development, do not have the genetic stability and integrity Symmetrical geometry. In recent years, I and some palm-lovers have encountered such problems in the maintenance and breeding of the less abundant cultivars of the planet: the spire with 5-sided planets and 3-sided spiny jade jagged in the growth period from time to time The return of ancestral phenomenon. So the adult plants, less than 3 years
