Effects of simulated alkaline stress on germination and seedling growth and development of mung bean

In order to provide the guidance for mung bean (Vigna radiata) cultivation in alkaline soil, the seed germination and seedling growth of mung bean under simulated alkaline stress was studied. The results showed that the alkaline tolerance of mung bean was strong. With the increasing of pH value (pH 7.0, 8.0, 9.0, 10.0, 11.0, 12.0), the seed germination rate was not significantly affected. However, with the increasing of pH value, the seed germination index and vigor index reduced. The taproot length, lateral root number, plant height and other morphological indicators of seedlings were reduced, and the concentrations of malondialdehyde (MDA) and soluble sugar in seedling leaves increased.
