Effect of Varying Levels of Manganese and PH on the Growth of Three Cultivars of Acer Rubrum    (View PDF)

E.A. Boyce and T.D. Sydnor

Abstract: A greenhouse study revealed that dry weights of new shoots and roots, and foliar levels of manganese of 3 cultivars of red maple ('Armstrong,' 'October Glory,' and 'Red Sunset') were unaffected by manganese levels in the nutrient solution during the duration of this experiment. Multivariate regression analysis of the factors affecting the percent of new stem growth showed that the percent of new stem growth of 'Armstrong' is lowered as pH is increased. The percent of new stem growth of 'October Glory' is unaffected by changes in pH and that of 'Red Sunset' is increased as the pH is increased.
