| Abstract | The aim of this work was to evaluate physiological and biochemical responses of faveleira under salinity. Plants were grown in nutrient solution containing 0, 50, 100 or 150 mM NaCl. After 8 days of stress, plants were harvested and separated into roots, xylopodium, stem petiole (SP), and basal, median and apical leaves. Salinity reduced the dry weight of all plant parts, although the indicators of water status were not changed. Salt stress increased the content of Na in the different plant parts, especially in xylopodium, in which it increased approximately eightfold while the content of K decreased by approximately 40 % under 150 mM NaCl. As a consequence, the K/Na ratio decreased in all plant organs. In stressed plants, the content of soluble sugars was increased in the roots, SP and leaf strata and the content of soluble proteins increased in all organs. The content of total free amino acids increased in the roots, SP and apical leaves, while the proline content increased in all organs except in xylopodium. It is suggested that the xylopodium may be involved in a mechanism of exclusion and/or compartmentalization of Na in faveleira under salinity to avoid ionic toxicity in the leaves. |
