The growth of sunflower plants in experimental stands was analyzed in terms of the growth of every internodal segment consisting of a leaf and a piece of stem. The growth of a single leaf and an internodal stem length were both successfully approximated by the simple logistic curves having the same coefficient of growth in common. Daily rates of gross photosynthesis, surplus production and weight increase of each leaf were calculated with Kuroiwa's formula based on the logistic growth of leaf area and stem length in combination with the known light-photosynthesis curve and other properties of sunflower plants. The growth in weight of each stem segment was also calculated on the assumption that the daily surplus production in all leaves was distributed to all internodal stem segments in proportion to their current length. Results of the calculation agreed fairly well with the actually observed patterns of stem growth and their change with plant density.
