Two laboratory experiments were conducted to study the influence of relative humidity, temperature, and light intensity during the boll‐opening period on cottonseed quality. Seed quality was reduced as relative humidity increased above 60% during a 21‐day exposure period. Increasing relative humidity from 60 to 70% caused a rapid decrease in rate of radicle growth of 5‐day old seedlings. Raising relative humidity to 80% and above resulted in a rapid increase in free fatty acids accumulated in seed oil during the exposure period. Raising temperature of exposure period from 25 C to 40 C at constant relative humidities had little influence on seed quality. Increasing light intensity from 50 ft‐c to 2,000 ft‐c at 35 C and 80% relative humidity did not influence seed quality.
