Using Low Temperature Exotherms Method to Analyze Branch Cold Resistance of Chinese Chestnut

doi:10.7668/hbnxb.2017.S1.035

Abstract

Abstract: The experiment was to verify the effect of low temperature exotherms analysis on identifying the cold resistance of chestnut.The test materials were annual dormant branches of 16 chestnut varieties(strain) from 8 provinces,the exothermic characteristics of each varieties and the correlation index of LTE were analyzed by LTE analysis method.Low temperature exotherms(LTE) of 16 chestnut varieties(strain) were recorded by differential thermal analysis(DTA),the regression line of injury-temperature(LT-I) of xylem and phloem were established by three-point method,the LTE correlation index(LT-I slope of xylem and phloem,the temperature of freeze beginning and freeze ending point of xylem and phloem) and the membership function method were applied to compare cold hardiness of 16 chestnut varieties(strain).Tissue browning and conductivity method were used to validated the correctness of low temperature exotherms analysis method.The LT-I slope of phloem was different from xylem,the LT-I slope of xylem and phloem were different among 16 chestnut varieties,and the LTE correlation indexes had significant differences.There was highly significant negative correlation between the average membership of LTE index and the temperature of freeze beginning and freeze ending point of xylem and phloem.There was significant positive correlation between xylem injury degree determined by LTE analysis method and xylem browning rate determined by tissue browning,and the correlation coefficient was 0.988.There was highly significant positive correlation between branch injury degree determined by LTE analysis method and branch injury degree determined by conductometry,and the correlation coefficient was 0.998.The results show that LTE analysis is a simple,accurate and practical method for identifying the cold resistance of Chinese chestnut.The lower temperature of freeze beginning and freeze ending point of xylem and phloem,and the bigger average subordination value of LTE indexes in the chestnut branches is,the more cold resistance capacity the chestnut variety has.
