Conteúdo: | Two sand culture experiments were conducted to determine the influenceof substrate pH on 'Waimanalo' papaya seedling growth, morphology, andmineral element nutrition. The seedlings were grown in clear, plastic tubes 7 cm in diameter and 21 cm in height with the rooting substrate being silica sand. The substrate was drenched daily with a complete nutrient solution. The solution was adjusted to target the pH at 3.0,4.0.5.0,60,70,8.0, or 9.0. Direct seeded plants were used in the first study and plants were harvested after 9,5 weeks of growth. Transplants were used in the second study, and plants were harvested after four weeks of growth. Dry mass of plants was relatively unaffected by substrate pH within the range of 4.0 to 9.0. In both studies, however, dry mass of plants receiving a target pH of 3.0 was reduced compared to thoseplants receiving the other pH level nutrient solutions.
