How does light affect germination
WebSalt stress affects germination percentage, germination rate and seedling growth in different ways depending on plant species[8]. Germination and seedling growth are reduced in saline soils with varying responses for species and cultivars[9]. Mung bean was determined to be moderately salt sensitive relative to other species[10]. Against these ...
