瓜叶菊[Senecio hybridtts(Willd)Regol]是菊科多年生草本花卉,一般作二年生栽培。由于其花色绚丽、花形丰满、花期又长,而成为冬、春的重要室内花卉。长期以来,我国各地都广泛栽培,但以往栽培的品种存在着植株高(30～60厘米),株形松散,观赏特性较差,生育期又长(6～8个月)管理费工且占用温室时间长等缺点,栽培存在一些困难。中国科学院植物研究所植物园温室组1980年自国外引入矮生早花瓜叶菊品种(S.hybridtts cv.‘Multiflora grandiflora’见我刊90年第二期封三彩页“保加利亚瓜叶菊”),经过九年多来的栽培观察,表明它是一个性状优异的矮生早花品种.其生物学性状及栽培特点如下;
Cineraria [Senecio hybridtts (Willd) Regol] is a perennial herbaceous flower Compositae, usually for biennial cultivation. Because of its brilliant colors, flower-shaped full, flowering and long, and become winter, spring, an important indoor flower. For a long time, cultivars have been widely cultivated in all parts of China. However, the varieties cultivated in the past have high plant height (30-60 cm), loose plants, poor ornamental characteristics and long growth period (6-8 months) Long greenhouse and other shortcomings, there are some difficulties in cultivation. Botanical Garden Greenhouse Group, Institute of Botany, Chinese Academy of Sciences Introduced S. hybrid tts cv.’Multiflora grandiflora ’from abroad in 1980, see my second issue in 1990, Bulgarian cineraria) The cultivation observation for more than nine years indicates that it is a short-flowering early-flowering variety with excellent traits, and its biological characteristics and cultivation characteristics are as follows:
