Abstract：Based on the data of gradient observation in hillside land of loquat and analysis of an experiment on young fruits harmed in low-temperature box,the grade index of freezing injury of loquat was preliminarily studied. The grade index of freezing injury of loquat was established on the basis of the daily extremely low temperature,that is:the mild freezing injury was -2. 5℃ < Tmin≤-1. 0℃;the moderate freezing injury was -3. 5℃ <Tmin≤-2. 5℃;the Severe freezing injury was -4. 5℃ <Tmin≤-3. 5℃;the serious freezing injury was Tmin≤-4. 5℃.
