| The effects of soil water potential on the growth of a 'drought-susceptible' and a 'drought-adapted' sugar cane varieties are described. The experiment was conducted in containers in a greenhouse and five water regimes were imposed as treatments. These consisted in allowing the soil water potential measured at 6" below the soil surface to decrease to a minimum of -0.25, -0.50, -0.75, -3.0 and -9.0 atm before rewatering to water saturation. Growth, as measured by stem dry weight, mean leaf area and shoot height increments, was shown to be directly related to soil moisture potential, the higher the potential the better the response. The difference between varieties in their response to the different treatments are emphasized. The 'drought-susceptible' variety was found to be adversely affected at higher soil water potentials than the 'drought-adapted' variety and this differential effect was attributed to differences in root growth and physiological adaptability of the varieties. Attention is also drawn to the importance of depth of soil measurements and it was found that measurements of soil suction at any one depth throughout the life span of the plant cannot be taken as the criterion for irrigation purposes. It is suggested that more attention be devoted to work on water potential of the plant itself and its relation to growth. | |
