Abstract
In order to investigate the effect of calcium on synthesis of phenolic compounds induced by salicylic acid(SA), Methyl jasmonate(MeJA), β-aminobutyric acid(BABA) and gentisic acid(GA) in tomato, the 3rd leaf was treated with above chemicals in six-leaf stage. At the sametime, these plants were sprayed with CaCl2, distilled water, LaCl3or EGTA respectively. And then, content of phenolic compounds in the 3rd(induced) and 5th(un-induced) leaves were assayed at different time after treatments. Results showed that:(1) Content of phenolic compounds both in induced and un-induced leaves increased after treatment with chemical elicitors. It reached the peak on the 2nd day after treated with SA, MeJA and GA or on the 1st day after treated with BABA.(2) Content of phenolic compounds induced by chemical elicitors was promoted by exterior Ca2+. Content of phenolic compounds in leaves treated with chemical elicitors and Ca2+was 10% above in leaves treated with chemical elicitors only. However, it was suppressed by calcium inhibitors such as Ca2+chelator EGTA and plasmalemma Ca2+channel blocker La3+ variously. Thus, we speculated that Ca2 +play a positive regulation role in the synthesis of phenolic compounds induced by chemical elicitors in tomato leaves.
