Abstract
Abstract High Mn in acid soils is sometimes toxic to plants. The Mn tolerance of triticale lines has not been established. The objective of this study was to determine the relative sensitivities of triticale ( X Triticosecale , Wittmack) lines from the Alabama germplasm grown on high Mn soil and in nutrient solution. Twenty‐eight lines were grown on an Mn‐toxic Greenville sandy loam ( Typic Hapludult ) at pH 4.7 and 5.8 (Experiment 1). Lines ‘AM 2149’, ‘AM 3384’, ‘6TA 131’, and ‘6TA 203’ which showed differential responses to lime in Experiment 1 were grown on the same soil limed to pH values of 4.7, 4.9, 5.2, 5.5, 5.8, and 6.1 (Experiment 2). The same lines were grown in 1/5‐strength Steinberg solution with 2, 4, 8, 16, and 32 ppm Mn added (Experiment 3) and adjusted daily to pH 4.6. The relative top growth on the soil (pH 4.7/pH 5.8) varied between 24 and 98% for AM 3384 and AM 2149, respectively. The relative growth in nutrient solution with 32 ppm Mn ranged between 33 and 84%, respectively for AM 3384 and 6TA 131. However, most of the cultivars had similar responses. The highest growth was obtained at pH 6.1 for the four cultivars tested (Experiment 2). The Mn concentrations in plant tops in the unlimed soil were not correlated to Mn sensitivities of the triticales. Nutrient solution studies indicated that 16 and 32 ppm Mn reduced plant growth when compared with lower Mn concentrations. Manganese tolerance rankings of cultivars were similar in soil and nutrient solutions. These data indicate that triticale lines can be selected for differential tolerance to Mn.
