Six weeks after sowing, seedlings were grown under soil moisture corresponding to 100, 75, 50 and 25% field capacity (FC) with or without PEN (15mgl−1) for 4weeks. Results showed that the seedlings at 75% FC showed maximum growth and water supply lower than 75% FC was the threshold of drought-initiated negative effects on seedling growth. Drought stress significantly induced proline and carbohydrate contents and the decreased chlorophyll, photosynthesis parameters, soluble proteins and ion accumulations. Exogenous PEN increased the growth parameters, pigments, photosynthesis and ion accumulations in drought stressed and unstressed plants, but the effects of PEN were more significant under water deficit conditions. PEN also reduced the negative effects of drought by osmotic balance and protein accumulations. Electrophoretic patterns indicated that PEN treatment increased the intensity of some protein bands with the molecular weights of 30kDa in shoot and 31kDa in roots, and several new protein bands with the molecular masses between 116 and 14kDa appeared in leaves, shoots and roots. These results suggest that the PEN application can be a useful tool in alleviation of effects of drought stress in M. pulegium plants. Prof. H.S.
