摘要
用适宜浓度的草酸或水杨酸在芒果挂果期对叶片和果实进行喷雾处理 ,可显著提高采后芒果对蒂腐病与炭疽病的抗性。在供试浓度范围内 ,对芒果蒂腐病的抗性诱导 ,草酸以 5 3mM的浓度为最好 ,水杨酸则以 0 1mM为最好。对炭疽病 ,草酸以 37mM、水杨酸以
Resistances to mango stem end rot and anthracnose were markedly induced by spraying appropriate concentrations of oxalic acid or salicylic acid on the leaves and young fruits of mango trees.Within the range of concentrations tested,oxalic acid and salicylic acid were the most effective for the induction of resistance to stem end rot at the concentrations of 53 mM and 0.1 mM,respectively.The most effective concentrations of inducing resistance to anthracnose were 37mM for oxalic acid and 11 mM for salicylic acid.
