Values followed by a different letter within the same column are significantly different at P = 0.05 probability level.
Carpel distribution rate = Carpel biomass/(carpel + seed + lint) biomass × 100; Seed distribution rate = Seed biomass/(carpel + seed +lint) biomass × 100; Lint distribution rate = Lint biomass/(carpel + seed +lint) biomass × 100; Lint/seed ratio = Lint/seed biomass.
