为了解孝顺竹的开花物候、开花动态以及花序特点,通过野外定位观察,对孝顺竹的开花生物学特性进行了观察和测定。结果表明:孝顺竹为假花序,假小穗簇生,为连续开花类型竹种;南京地区孝顺竹花芽一般在10月初开始分化,次年4—5月小花盛开;盛花期小花内、外稃张开,雌蕊柱头伸出,雄蕊花丝伸长,花药伸出稃外;果实为颖果。
In order to understand the flowering phenology, flowering and inflorescence characteristics of filial bamboo, the flowering biological characteristics of filial bamboo were observed and determined by field observation. The results showed that filial bamboo was a cluster of false inflorescences and spikelets of spikelets, which was a continuous flowering type of bamboo species. The filial buds of filial pines in Nanjing generally began to differentiate in early October, with small flowers in April - May of next year.
