Abstract:

The inductive and time effect of different concentrations of MeJA on the lignin contents，the crystal cell number and water potential of Prunus mongolica leaves were studied，to find out whether MeJA have defence reaction on Prunus mongolica.The results showed that the lignin contents and the crystal cell number increased significantly after MeJA treatment，but water potential decreased remarkably.The lignin contents reached the maximum on the 3th day,and it had no difference with CK after treated by 3 concentrations of MeJA;the effect of 0.10 mmol/L MeJA treatment had more significart difference than the others (P<0.05).MeJA treatment obviously decreased water potential of the leaves than CK (P<0.05) after treated by 3 concentrations of MeJA for 1 day;water potential first increased and then decreased after treated 3 and 5 days,which was lower than CK,but had no significant difference (P>0.05).The crystal cell number of Prunus mongolica leaves was obviously higher than CK after treated by 3 concentrations of MeJA.
