Abstract

Abstract

Different night temperatures were maintained throughout the seed development period of two divergent varieties of cotton growing in the field during the 1963, 1964, and 1965 seasons. Viability and oil and nitrogen content of cottonseed of both varieties were found to be affected by the night temperature prevailing during the seed development period. Decreased night temperatures resulted in lower germination percentages and in reduced oil and nitrogen content of the seed. Differences were also noted between varieties and seasons, and an inverse relationship existed between oil and nitrogen content for both varieties at all temperature regimes.
