Access from EThOS:
Tomato species and cultivars, Lycopersicon esculentum L. cv. Ailsa Craig and Solairo, differing in drought resistance were investigated for their water relations, stomatal responses and abscisic acid (ABA) content when exposed to soil drying treatment (SD). Under SD treatment, the reduction in plant height, leaf length and leaf area has been attributed to the decrease in leaf water potential and relative water content. Stomatal conductance of Solairo cv. was more sensitive to SD treatment than Ailsa Craig cv. and ABA content was found to be higher in it's xylem sap. There is a strong relationship between soil moisture content and stomatal conductance, ABA content and leaf water potential for both cultivars.
