Abstract
In glasshouse experiments, sorghum cv. BR 64 grown in nutrient solution supplied with 0, 10, 50, 100, 500, 1000, 2000 or 4000 ppb Mn, was harvested 59 days after transplanting at the early 2-leaf stage. For maximum growth, the critical concentration of Mn in the leaf blade tissue was 10 ppm. The flag leaf (leaf 1) or leaf 2, sampled at boot stage, were the most sensitive indicators. This critical level increased to 60 ppm for leaf 5 and the stem tissues were poor indicators as they had a narrower range of Mn content. Mn-deficient plants of BR 64 exhibited brown-red pigmented bands in interveinal areas, as well as the usual interveinal chlorosis observed with other cultivars
