摘要
冷冬是影响云南省樟树生产的重要原因之一。经低温处理云南樟、新樟、细叶香桂、银桂4种植物的离体新鲜叶片后,用电导法测定叶片浸提液电介质渗出率,并计算各植物的半致死温度。根据半致死温度,就能合理布局云南省云南樟、新樟、细叶香桂和银桂的生产。
This paper concerns an approach to a rational distribution of Cinnamomum glanduliferum, C. mairei, C. subavenium, Neocinnamomum delavayi iu Yunnan Province by preventing them from the freeze injury occuring there frequently. Cut fresh leaves from the crops were treated at low temperatures. Then osmotic percentages of the electrolyte in the leaf extractant were determined with the conductance method.Further, the semilethal temperature of each of the camphor species was worked out for setting about the distribution.
