Abstract
The effects of some amino acids and phenolic compounds on the recovery of chlorosis in Fe‐deficiency susceptible sorghum cultivars were examined. Fe‐deficiency chlorosis was induced in cv. CS‐3541 and 1‐serine, 1‐glutamic acid, or 1‐cysteine (10 μg/ml) was supplied through a leaf for 4 hrs. Chlorotic plants treated with serine turned green in 12 days, and the pH of the medium was reduced. In another experiment, leaf application of serine or anthranilic acid resulted in recovery from chlorosis and also a decrease in the pH of the root medium. Root supply of salicylic acid (4 mg/1) caused recovery from chlorosis. When sorghum cv. 168 were raised from seeds soaked in phenylalanine (50 μg/ml) and subjected to Fe‐deficiency stress, the plants developed chlorosis, but recovered from it after 4 days, with a reduction of the pH of the nutrient medium to 3.6. The results indicate that a number of factors are involved in inducing the roots of Fe‐deficiency stressed plants to produce the “reductants”;, and some amino acids and chemicals like salicylic acid could influence the mechanism.
