Embodiment Construction

[0042] 1. Treatment of test materials

[0043] From October, as the climate gradually turns from autumn to winter, the temperature gradually drops. Two varieties of Shuchazao and Wuniuzao are taken from the tea garden of Dayang Town, Hefei City, Anhui Province every month, and the content of the leaves in the leaves is determined by high performance liquid chromatography. Sucrose content, continued until January of the following year, and compared the changes in the sucrose content of the two varieties.

[0044] 2. Determination of sucrose content

[0045] A. Sample Extract Preparation

[0046] 1) Take 25g of mature fresh leaves of tea tree and cut them into 0.2-0.5cm 2 debris;

[0047] 2) Add the shredded leaves in step 1) into 250 mL of pure water, and extract them in a water bath at 90° C. for 1 hour under sealed conditions; the percentage by weight of leaves and pure water extraction is 1:10;

[0048] 3) Take out the extraction solution in step 2) and cool it to room tem...

Abstract

The invention belongs to the field of botany, and particularly relates to an early evaluating method for tea tree winter resistance. The soluble sugar (mainly cane sugar) content is one important physiological basis for the strength of the tea tree winter resistance and one important presentation of the low temperature adaptability of the tea tree variety; and as the temperature is gradually lowered with the approaching of the winter, the cane sugar content of the tea tree leaves is gradually increased, however the tea tree variety with high winter resistance has higher-increased cane sugar content than the tea tree variety with low winter resistance. The early evaluating method for the tea tree winter resistance evaluates the winter resistance of the tea tree by measuring the cane sugar content in the tee tree leaves, so as to evaluate and select the tee tree variety with high winter resistance and provide basis for variety introduction for the tea tree.

Description

technical field [0001] The invention belongs to the field of botany, and relates to a method for identifying cold resistance of tea trees, in particular to a method for identifying cold resistance by measuring sucrose content in leaves of tea trees. Background technique [0002] my country is the origin of tea trees, and it is also the first country in the world to grow tea, make tea, and drink tea. my country has a history of more than 3,000 years of artificial cultivation of tea trees. Tea is my country's "national drink" and is a big country in tea production and consumption. The planting area of ​​tea trees is 1.8 million hectares, and the output exceeds 1.3 million tons, ranking first in the world. Tea is also recognized as the most important natural health drink in the world. Tea is grown in 60 countries around the world, and tea is imported from more than 150 countries and regions. More than 2 billion people love tea. With the change of consumption concept of healthy ...
