为了研究刺黑竹(Chimonobambusa neopurpurea Yi)生根和秆芽发育规律，以加强刺黑竹育种和应用的理论基础，以南京引种的刺黑竹为试验对象，通过表观形态学观察以及滑走切片等方法，一方面对刺黑竹气生根的发育机理进行探讨，另一方面对刺黑竹气生根和秆芽在不同部位节间的发育变化规律进行研究。结果表明：高生长结束时，刺黑竹竹秆气生根的发育是自基向顶的，竹秆基部的气生根发育最早，也最先达到成熟，靠近基部为刺状的气生根，表现为木质化程度较高的深褐色刺状组织，越往秆稍则气生根的发育越为迟缓；而刺黑竹竹秆节部芽的生长则表现为竹秆中部17至19节部生长最快，基部和稍部生长相对较慢。切片表明气生根的发育方式为内起源，而秆芽为外起源。刺黑竹幼秆气生根与秆芽的生长及分布具有明显的规律性，了解并利用这种规律将有助于以刺黑竹为主的方竹属竹种的育种与推广。
In order to strengthen the breeding and promotion of Chimonobambusa neopurpurea Yi, we studied the variation and development mechanism of aerial root and stem buds at different nodes of young Chimonobambusa neopurpurea Yi by means of morphological observation and sliding section. Results showed that the development of aerial root was from base to top after height growth, and the aerial root at the base of the bamboo culm was the most mature. In the first node of the base, the aerial root was dark in color and hard in texture, with a hemispherical ridge surrounding the node for a week. It changed to be spiny from the second node, presenting as dark brown spiny tissue with high degree of lignification. The further up, the development of aerial root was delayed, and only the light green ridge could be observed in the middle of bamboo culm. Stem buds grew fastest at 19-22 nodes, but it slowed at the base and top. The aerial root was endogenous in origin, while the stem buds were the external origin. The growth and distribution of the aerial roots and stem buds of young Chimonobambusa neopurpurea Yi have obvious regularity, which would help us to breed and promote this kind of bamboo.
