Photosynthate and Dry Matter Partitioning in Short‐ and Long‐Season Cotton Cultivars

Differences in source‐sink relationships between short‐ and long‐season cotton ( Gossypium hirsutum L.) cultivars, the contribution of main stem leaves to boll growth, and the distribution of nonstructural carbohydrates late in the season are not well understood. This study compared the cultivars Tamcot CAMD‐E (a short‐season type) and Stoneville 213 (a long‐season type) for two seasons in the field. To study photosynthate partitioning, the...
