对欧洲葡萄茎木质部截面上液流传导区域进行了定量研究。首先建立了一个木质部截面上导管总体分布的数量模型;然后对木质部截面上液流传导功能导管进行了区域定量研究;并且讨论了木质部不同年轮对液流传导的相对重要性和不同年龄茎干木质部液流传导的有效性估计;最后建议将欧洲葡萄植物木质部水导构造称为“外围散孔型”构造。
A quantitative study of the flow-conducting region of the cross-section of the xylem in the European grape stems was conducted. Firstly, a quantitative model of the overall distribution of the conduits in the section of xylem was established. Then, the regional quantitative study of the conduits in the section of xylem was conducted. The relative importance of different annual rings on the flow conductivity of xylem and stems of different ages Xylem flow conductivity of the validity of estimates; Finally, the proposed European grapevine xylem water conductivity structure as a “peripheral scattered pore type” structure.
