摘要

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。

Abstract

The flowering phenology, flowering dynamic and flowering biological characteristics of Bambusa multiplex were observed and detected by positioning through the field observation. The biological characteristics are as follows: Bambusa multiplex belongs to indefinite inflorescence. False spikelets cluster in every nodes of culms and branches. Bambusa multiplex is a continuous flowering bamboo species. In Nanjing the flower buds usually begin to differentiate in October of last year while are in bloom in April and May next year. During the period of full bloom palea and lemma open first, then stigmas protrude and the anthers extend with the filaments elongate. The fruit is the type of caryopsis.
