The Research On Bambusa Multiplex Cv. Alphonse-Karr's Characteristics And Landscape Application

The research is about the Bambusa multiplex cv. Alphonse-Karr which inhabit in Haikou, Zhanjiang, Nanning, Guilin, Shaoguan, Changsha and Yiyang. The research inquire the difference of Bambusa multiplex cv. Alphonse-Karr's physiology characteristic among the seven city and the correlation between the difference and climatic factors. On the basis of this research, we can find the right way for Bambusa multiplex cv. Alphonse-Karr's landscape application. Improvements of the research in this paper are as follows:1. Physiology characteristics research. For the leaves of Bambusa multiplex cv. Alphonse-Karr in each region, the content of chlorophyll are more in summer and less in winter, as well as the content of free amino acids. And we found the content of chlorophyll in the leaves of Bambusa multiplex cv. Alphonse-Karr changed between4.91-5.47mg/g, while the content of free amino acid changed between3.5-4.18(mg· FW·(100g)-1). The leaves in south have more chlorophyll and free amino acids than which in north. On the contrary, we found the content of β-carotene and the activities of nitrate reeducates in the leaves reduced from north to south in this reaserch. As the Pearson analysis has indicated, the variation of the content of β-carotene is significantly related to the activities of nitrate reeducates, and the correlation coefficient is0.809. Among all climate factors, temperature is the most significant factor, which can make great influence on the physiology characteristic of Bambusa multiplex cv. Alphonse-Karr.2. Landscape application research. By the reaserch on the physiology characteristic of Bambusa multiplex cv. Alphonse-Karr, we can draw a conclusion that Bambusa multiplex cv. Alphonse-Karr adapt to the climate in north more than in south between the region from20°01'N to28°53' N. We should pay attention to this point in landscape application. As a good landscape material, Bambusa multiplex cv. Alphonse-Karr can be used for not only main features but also subordinate plants. What's more, it even can be used in potted landscape.
