Abstract:
P.pseudocerasu L.‘Manaohong’ that infected with phytoplasma diseases was used as test materials.Exogenous methyl jasmonate (0.1 mmol·L-1)，melatonin (0.1 mmol·L-1) and tetracycline (1.0 mmol·L-1) were used to treat the diseased seedlings，and the effect of exogenous substances on the disease resistance of plants was studied，in order to provide reference for the prevention and control of the disease of P.pseudocerasu L.‘Manaohong’ infected by phytoplasma.The results showed that these three substances could significantly increase the contents of N (nitrogen)，P (phosphorus)，Mn (manganese)，and Mo (molybdenum) in the leaves of infected plants.Moreover，all of them could enhance the plant height，leaf width and leaf length of the diseased plants.And the effects of methyl jasmonate and tetracycline were better than that of melatonin.
