Abstract

The invention provides a high-efficiency living body identification method for the cold-resistant performance of a plant. The method comprises the following steps: (1), measuring the capacitance of asuitable part of a mature leaf of a plant by using a capacitance tester; (2), comparing capacitances of the same parts of different types of mature leaves of plants and indicating the low cold-resistant performance of the type by the lower capacitance. According to the invention, the capacitance tester measures the capacitances of suitable parts of the mature leaves of the plants at field to identify and compare the cold-resistant performance relationship of different types of plants. Because the method does not require the low temperature stress process of the plant sample, the method can beperformed at a normal temperature. The method has characteristics of simpleness, great convenience, high accuracy, and non-destructive detection and is novel method for measuring the cold-resistant performance of a plant in field efficiently and rapidly.

Description

technical field

[0001] The invention relates to a plant cold resistance identification method, in particular to a plant cold resistance high-efficiency living body identification method. Background technique

[0002] Avocado (Persea americana Mill.) is a kind of fast-growing evergreen tree fruit tree of Lauraceae Avocado, also known as avocado, avocado, commonly known as avocado. Avocado is a famous tropical and subtropical fruit tree that originated in Central America, tropical humid areas of Mexico and higher altitude mountain forests or tropical plateaus. Avocado was introduced to China in 1918 and is now distributed in tropical and subtropical regions such as Hainan, Guangdong, Guangxi, Guizhou, Yunnan, and Taiwan. Low temperature is an important limiting factor for fruit tree cultivation. Avocados often suffer from severe cold damage due to low temperature in winter in northern Guangxi and Guizhou subtropical high-altitude areas. In some cases, the branches and leaves ...
