Abstract

Phaseolus vulgaris has a great variability regarding the tolerance to saline stress, starting with values of 1 - 5 atm NaCl P.O.The seeds from the control variant V0 were moistened with distilled water. Also we studied the proline content in stresed bean variant. The experimental results achieved made evident the existence of some bean genotypes with a good tolerance to salinity regarding germinative response (Tincova), free proline acumulation (Santana) and dry matter content (Tincova). These genotypes have recorded during germination normal intensities of radicle growth and cotyledon development, and they have synthesized important amounts of free proline with osmoprotector role. We also measured the of stressed genotype.
