Abstract:
Mungbean (Vigna radiata L.) is an important grain legume in Bangladesh belonging to the
family Fabaceae. As an excellent source of vegetable protein. Its edible grain is characterized by good
digestibility, flavor, high protein content, and absence of any flatulence effect. The lysine content makes
mungbean a good complementary food for rich-based diets because lysine is usually the first limiting
amino acid. Besides, the crops can enrich soils through nitrogen fixation (Sharma and Behera, 2009).
Plant growth and productivity are affected by nature’s wrath in the form of various abiotic stress factors.
Plants are frequently exposed to a plethora of stress conditions such as salt, drought, oxidative stress, and
others. All these stress factors are a means for plants and prevent them from reaching their full genetic
potential and limit crop productivity worldwide. Lack of adequate soil moisture in the seedbed is a major
obstacle to the establishment of the crop because inadequate soil moisture can reduce germination, slow
down seedling growth and decrease yield. There are many strategies have been adopted to overcome the
negative effects of drought. A good strategy for overcoming drought stress is seed pre-sowing treatments
(Ghiyasi et al., 2008). Seed priming was defined as pre-sowing treatments in water or in an osmotic
solution that allows the seed to imbibe water to proceed to the first stage of germination, but prevents
radical protrusion through the seed coat (Yari et al., 2012). Seed priming techniques have been used to
accelerate the emergence of more vigorous plants. Primed seeds usually to exhibit an increased
germination rate, greater germination uniformity, and greater total germination percentage. Increased
germination rate and uniformity have been attributed to metabolic repair during imbibitions build-up of
germination-enhancing metabolites. ...
