刚竹属竹种属于多年生一次结实植物,毕生开花一次,花后营养体自然死亡。竹子开花由内部计时机制所控制,这种计时机制对环境干扰有强大的缓冲能力。同步开花是刚竹属开花的基本特征。不同竹种的开花周期有很大差异,短的不足20年,长的可超过100年。开花周期的不稳定性可用基因突变和天然复壮来解释。竹株开花时植物激素的种类和含量上均有变化,但植物激素是否参与成花过程尚不清楚。
Phyllostachys bamboo belongs to a perennial strong plants, flowering once a lifetime, after nourishing the body of natural death. Bamboo flowering is controlled by an internal timing mechanism, which has a strong buffer against environmental disturbances. Synchronous flowering is the basic characteristics of the genus Phyllostachys flowering. Different bamboo species flowering period is very different, less than 20 years short, long can be more than 100 years. Instability of flowering cycles can be explained by genetic mutations and natural rejuvenation. Bamboo plant flowering when the type and content of plant hormones have changed, but whether plant hormones involved in flower process is unclear.
