| Abstract: |
| In order to study the effects of a new soil conditioner, M3T, on drought resistance of crops, a pot-based experiment applying M3T with different concentrations on maize seedlings under drought was carried out. The results showed that M3T improved water-holding ability of soil and prolonged the life time of maize seedling by 3～11 days. It also increased height and biomass of maize seedlings. Dynamic examinations on contents of chlorophyll, MDA, Pro, soluble protein, POD and SOD in maize seedlings showed that maize seedlings without any M3T treatment displayed earlier physiological responses to water stress than those with M3T treatment. It was further found that 0.01%～0.05% M3T promoted the plant growth, and 0.04%～0.05% M3T enhanced the drought resistance and prolonged the life time of maize seedlings. In conclusion, 0.02%～0.03% M3T was optimal for the growth of maize seedlings under drought. |
