Morphological characteristics and germination of P. dilatatum seeds following priming treatments

A study was conducted to assess the morphological characteristics and to evaluate the effectiveness of primingtreatments in enhancing the germination of Paspalum dilatatum Poir. seeds. The average length, width and thickness of the P. dilatatum seeds, were 2.88mm, 1.87mm and 0.87mm respectively. The...
