Sepals imbricate, rarely valvate, enlarged or not enlarged in fruit; petals imbricate in bud.

萼片覆瓦状，很少镊合状，扩大在果期不扩大的或；花瓣在芽中成鳞状。

Based on one new preservation solution which is made from carboxymethyl chitosan and sucrose for cut Gerbera flower , an effective research of preservative effect for extending vase life of cut gerbera flower is proposed in this paper, which is by exploring the percentage of moisture, pH and relative permeability of velamen to the petal organizations.
