Use of Morphological, Physiological and Biochemical Criteria in The Identification of Tolerant Caraots to Water Stress
Keywords:
Phaseolus vulgaris L., stomata, phenols,, prolineAbstract
The lack of water for irrigation or its shortage has drastic effects on the performance of beans, so it is essential to have materials resistant or tolerant to water stress. The objective of this work was to identify and characterize 22 cultivars of beans from Cuba and Venezuela based on their tolerance to water stress. Two irrigation treatments were applied: 70% and 20% of the field capacity (CC), and both were evaluated the relative water content (CRA), the stomatal opening, the stomatal index, proline content and total phenols in leaves.
