Effects of seed size on soybean performance: germination, growth, stress resistance, photosynthesis, and yield.

ABSTRACT:

Background

Seed size is an important quality trait in crops and is one of the key factors affecting crop yield; however, how seed size affects growth and physiological differences, stress resistance, and yield characteristics is unclear.

Methods

In this study, the effects of different seed sizes on germination, morphology, physiological characteristics, and yield traits of soybean were studied by combining germination, pot, and field experiments using Kenfeng 16 and Heinong 84 varieties.

Results

The germination potential, rate, and index, as well as the vigor index of very small seeds, were significantly lower than those of other seed sizes. Plant height and leaf area followed the order: large > medium > small > very small seeds. Dry matter accumulation in each organ
