Overwintering performance of four species of Machilus Nees in Jingzhou City
A comparative experiment was conducted on the winter cold resistance of four species of Machilus Nees plants.The freezing degree damage of leaves before and after overwintering was compared,and the physiological indexes such as electrical conductivity,soluble protein content,peroxidase activity,catalase activity,free proline content,malondialdehyde content and pigment content of leaves before and after overwintering were measured.The results showed that after natural low temperature,Machilus microcarpa had the lightest degree of freezing damage and could successfully overwinter,while Machilus ichangensis,Machilus phoenicis and Machilus duthiei had the greatest degree of freezing damage.The comprehensive evaluation showed that the cold tolerance of the four kinds of Machilus species was as follows:Machilus microcarpa>Machilus duthiei>Machilus phoenicis>Machilus ichangensis.
