Abstract

Abstract: The physical characteristic of different size maize of a cultivar Yedan 22 during seed-seedling transformation was studied.The germination vigor of the smaller size seed is significant greater than that of the bigger size seed and the both have no significant difference on germination capacity.The smaller size seed has greater substance transferring rate and substance consuming rate than the bigger size seed,while the earlier has lower substance efficiency than the latter.The bigger size seed has higher ATP content than the smaller size seed,which is more remarkable since four days after germination.

Key words: Maize, Seed size, Seed-seedling transformation, Physical characteristic
