ABSTRACT
The distribution of assimilates between root and shoots of the cotton plant is a complex process. Temperature of the soil and the air surrounding the above-ground portion of the plant has a significant influence on the growth of cotton shoots and roots. Soil physical properties may have a significant influence on cotton root-shoot relationships. Generally, increases in soil strength result in a decreased root growth, while shoot growth may be reduced or remain the same depending on other environmental factors. Cotton root distribution may be altered because of a reduction in soil water content. The production of fruit in cotton has a very dramatic influence on growth of the shoots and roots. Genetic variability has been observed in both cotton shoot and root development. An understanding of the dynamics of carbon production and partition into roots and shoots is important to the development of more efficient water and nutrient management systems.
