• Resumen

  • Influence of the leaf area on transpiration rate was investigated in Agave americana and Aloe vera. After six weeks of irrigation, the leaf area in A. americana ranged from 141 mm2 to 522 mm2, while in A.vera it ranged from 16 mm2 to 381mm2. The transpiration rate varied from 1.05×10-5 mol m-2 sec-1 to 1.14×10-4 mol m-2 sec-1 on the abaxial and adaxial leaf surfaces, respectively, in A. americana. In A. vera, the rate of transpiration varied from 6.17×10-5 mol m-2 sec-1 on the abaxial surface to 4.70×10-4 mol m-2 sec-1 on the adaxial surface. Although the leaves are larger in A. americana than in A. vera, the transpiration rate was higher in A. vera than in A. americana.
