Abstract:
Seven main cultivated persimmon varieties were used as experimental materials.Three infection methods，namely field resistance evaluation，in vitro inoculation of tender branches，and in vitro leaf disc infection，were adopted to study the consistency of the infection results of different resistance evaluation methods，the differences in resistance to anthracnose among different varieties，and the correlations between variety resistance and physiological indicators such as soluble sugar content，lignin content，peroxidase (POD) activity，superoxide dismutase (SOD) activity，and hydrogen peroxide (H2O2) accumulation.Meanwhile，using the highly resistant variety ‘Jixinhuang’ and the highly susceptible variety ‘Xiaoguotian Persimmon’ as test materials，the content changes of different hormones such as salicylic acid (SA) and jasmonic acid (JA) in different resistant varieties were studied,to clarify the resistance differences among different main cultivated persimmon varieties to anthracnose，effectively identify the disease resistance of persimmon germplasm resources，screen the key physiological indicators affecting resistance，in order to provide a reference for the screening of anthracnose-resistant resources and the study of its mechanism.The results showed that there were significant differences in the resistance of different varieties to anthracnose.‘Jixinhuang’ showed high resistance，‘Yuanqu Bayuehong’ showed disease resistance，‘Liquanshangeda’ showed moderate resistance，‘Qiyuexian’ showed susceptibility，and ‘Fuping Jian Persimmon’‘Qujing Shui Persimmon’，and ‘Xiaoguotian Persimmon’ showed high susceptibility.The resistance level of varieties to persimmon anthracnose was significantly positively correlated with soluble sugar content，lignin content，and POD，SOD activities (P<0.05).Among them，SOD activity was extremely significantly positively correlated with variety disease resistance (r=0.923 6，P<0.001).In the early stage of infection (0-12 hours)，the SA content showed an obvious upward trend，and the SA content in highly resistant varieties was significantly higher than that in highly susceptible varieties.Exogenous SA could significantly inhibit the growth of Colletotrichum horii.The results of in vitro branch infection and leaf disc methods were basically consistent with the field resistance evaluation results，which could be used as effective methods for the rapid identification of resistant varieties.During the defense process of persimmon trees against anthracnose infection，the changes in physiological indexes related to lignin and SA were closely related to disease resistance and could be used as important indexes for rapid screening and evaluation.
