摘要

Studies on the physiological and biochemical aspects of mite-plant interactions were conducted on different host plants: chrysanthemum, bean and cucumber growing under greenhouse conditions or in the open. The growth of plants injured by mites was studied after different periods of mite infestation. It was found that mite populations at low densities can stimulate the growth of injured plants as well as their photosynthetic activity by about 10-15 percent compared to uninjured plants. Photosynthetic activity in strongly injured leaves of experimental plants was much lower than in uninjured leaves. The decrease in CO_2 assimilation was positively correlated with chlorophyll reduction and disturbance in assimilate distribution. The oxidative processes in leaves of injured plants were very active during the entire period of mite feeding. The rate of dark respiration was about 20 percent higher in leaves infested with rnites compared to uninfested leaves. The activity of oxidative enzymes, peroxidase(1.11.1.7 and polyphenol oxidase (1.10.3.2) in mite infested cucumber plants was increased as a result of mite feeding. It created a suitable situation for the oxidation of phenolic compounds. The content of soluble sugars m injured leaves after a shortperiod of mite feeding was usually low, while their production, translocation and accumulation into starch were accelerated. At the beginning of mite feeding the amino acids concentration in injured chrysanthemum leaves was lower than in healthy leaves,and increased as mite injury became greater. Changes in the concentration of amino acids were also observed in injured cucumber leaves. During a penod of mite feeding some changes in the concentration of primary and secondary metabolites in the host plant can be connected with defence reactions of the host. Differences in the reactions of susceptible and resistant varieties were also noticed.
