  • Title: [Mechanisms of high temperature-induced Pseudoperonospora cubensis resistance of cucumber].
    Author: Shi YX, Li BJ, Liu XM.
    Journal: Ying Yong Sheng Tai Xue Bao; 2007 Feb; 18(2):389-94. PubMed ID: 17450745.
    Abstract:
    This paper studied the effects and control efficiency of high temperature on the pathogenicity and occurrence of Pseudoperonospora cubensis. The results showed that the P. cubensis resistance of cucumber was most obvious after treated at 40 degrees C for 2 h or at 45 degrees C for 1 h, with the control efficiency being 58. 40% and 45. 81% at the forth day, and 39. 35% and 37. 65% at the sixth day after P. cubensis inoculation, respectively. Under high temperature, the activities of peroxidase (POD), phenylalanine ammonia lyase (PAL) , chitinase (Cht), beta-1,3-glucanase (Glu) in cucumber leaf were significantly higher, and large amount of lignin was deposited on the cell wall of leaf tissue, indicating that after treated with high temperature, cucumber plant manifested an induced P. cubensis resistance.
