南天竹栽培性状研究

摘要

[Objective] This study was to systematically investigate the cultivated characters of Nandina domestica and to lay a foundation for breeding, cultivating, as well as its application in landscape. [Method] Using N.domestica populations from 13 different areas of Hunan Province as tested samples, the cultivated characters of N.domestica in both the cultivated type and wild type were systematically studied through field experiment and comparative analysis. [Resul] The phenological features of N.domestica from different areas and germplasm resources were basically identical; the growth patterns of cultivated type and wild type were also basically identical, but the cultivated type grew faster than the wild type; both the two types grew quickly at young stage, and either the annual growth of new shoots or the growth pattern of leaves confirmed the fitting curve of the Logistic equation. [Conclusion] This research provided basis for the exploitation and utilization the germplasm resources of N.domestica.
