Studies on germination, vigor and dormancy in cotton seed as affected by maturity were conducted. Results showed that the three varieties of cotton seed reached physiological maturity at 40 days after flowering, as indicated by maximum seed dry weight, at which seed moisture content was around 45%. After physiological saturity, seed moisture content rapidly decreased, and was around 9% at 50 days after flowering. Maximum viability was found at 40-50 days but freshly harvested seeds showed maximum germination capacity at 50 days while maximum germinability was at 45-50 days in air-dried seeds stored for two months. This was possibly due to seed dormancy. Cotton seed dormancy was found in these freshly harvested seed at 40 and 45 days after flowering. Dormancy was non-existent at 50 days, or when seed moisture was below 10%. Seeds harvested at 55 and 60 days after flowering decreased in seed viability and germination. Seed vigor as determined by speed of germination, seedling dry weight, TZ energy, cold test and field emergence was at its maximum at 50 days after flowering. Since cotton seed dormancy varied among seed lots depending on maturity, any growth test which requires germination or resumption of growth is not satisfactory here for testing vigor; TZ energy is more favorable.
