毛竹Pleioblastus chino var.Hisuchii是一种重要的观赏竹种，很少开花。目前尚缺乏对其开花前后物质性质变化的研究。本文采用生物木材科学的方法，对竹材开花前后的解剖、化学和力学性质进行了研究。结果表明，开花后纤维、维管束和维管束的形态和比例降低，维管壁凹陷的开口明显增大，抽出物、木质素、综纤维素、纤维素和戊糖等主要成分含量上升，灰分含量下降。密度和断裂模数下降，弹性模数明显下降，而微纤丝角和结晶度增加。总体而言，竹子开花竹的强度下降，养分运输能力增强，这与竹子内部结构和性质的变化密切相关。这意味着竹子开花可以通过一些特性(如凹坑和弹性模数)的显著变化来监测或预测，为进一步研究竹子开花衰老和延迟开花机理提供参考。
Pleioblastus chino var. hisauchii is an important ornamental bamboo species that rarely flowers. Studies on the change in its material properties before and after flowering were lacking. In this paper, the anatomical, chemical, and mechanical properties of bamboo culms before and after flowering were studied by using the method of bio-wood science. The results showed that after flowering, the morphology and proportion of the fiber, vessel and vascular bundle decreased, and the openings of pits in the vessel wall were enlarged significantly; the contents of the main components such as extractives, lignin, holocellulose, cellulose and pentosan rose, while the ash content dropped. There was a decrease in density and modulus of rupture, and a pronounced fall in modulus of elasticity, while the microfibril angle and crystallinity increased. In general, the strength of bamboo flowering culms decreased and the ability to transport nutrients increased, which were closely related to the changes in internal structure and properties. This meant that bamboo flowering may be monitored or predicted by significant changes in some properties (such as pits and modulus of elasticity) and provide a reference for further research on the mechanism of flowering senescence and delayed flowering in bamboo.
