Conteúdo: | The effects of nutrient solution pH (4.0, 5.0, 6.0 and 7.0) were examined on growth features of 12alfalfa genotypes in relation to characters: leaf blade, epicotyl, hypocotyl, first leaf petiole, trifoliateleaf petiole and root fresh weight and epicotyl, hypocotyl, first leaf petiole, trifoliate leaf petiole androot length. Significant quadratic effects of pH solution were detected for all studied parameters.The pH value which resulted in maximum growth varied, according to the studied parameter,between 5.0 and 6.0. The genotypes Victoria, Esmeralda, Crioula and F-708 exhibited superiorperformance when data were pooled for all studied pH values. The results indicate that the initialgrowth is affected by pH variation in the nutrient solution, and that contrasting genotypes tend toperform alike.
