Fruit (boll) transpiration rates in cotton ( Gossypium hirsutum L.) may be important in boll growth and movement of materials into developing bolls. Therefore to facilitate comparisons of transpiration rates of different age (and size) bolls, a nondestructive method for the estimation of cotton boll surface areas was evaluated using two commercial cultivars grown in the greenhouse. Boll length was linearly related to boll area for both ‘Stoneville 213’ and ‘Deltapine 16’ cottons by an equation of the form LOG 10 Y = a + b LOG 10 X, where a and b are regression coefficients, and Y and X are boll area and boll length, respectively. Since no significant differences were found between the individual equations for the two cultivars, a composite regression equation was computed which can be used for boll area estimations for both cultivars.
