The results showed that the germination percentage in the large seeds was the highest (100%), and the size of the seeds affected the length of the root and shoot as the large seeds gave the highest length for root (8.37 cm) and shoot (14.2 cm) compared to the medium and small seeds. So, for these results, the seed size is closely related to root and shoot length, number of leaves.展开更多
