Abstract
Taking tomato(Lycopersicon esculentum Mill.)variety'L402'seedling as material,we investigated the effect and physiological mechanism of calcium to methyl jasmonate(MeJA)inducing tomato resistance to gray mold after treated the tomato leaves with MeJA,Ca2+ or inhibitor of Ca2+.The results showed that:(1)Resistance to tomato gray mold was improved significantly after the plant treated with MeJA.Induced resistance was farther enhanced by Ca2+ but restrained badly by chelator as EGTA or the plasmalemma Ca2+ channel blocker as LaCl3.(2)Activities of PAL,PPO and POD also rose after the plant treated with MeJA.The response was generally promoted by exterior Ca2+ and suppressed by the inhibitor of Ca2+ such as EGTA and LaCl3.(3)However,activities of CAT and SOD induced by MeJA were not regulated by Ca2+ or inhibitor of Ca2+.Consequently,modulating of calcium on the induced resistance to tomato gray mold by MeJA may have relations with activities of defensive enzymes such as PAL,PPO and POD in tomato leaves.
