摘要: A pot experiment was carried out to investigate the effect of iron supplementation on physiological and biochemical status low-chill peach cultivars (Saharanpur Prabhat, Shan-e-Punjab Pratap) suffered from chlorosis in artificially created calcareous soil. Three most commonly used sources viz. Fe-sulphate (1.0 % 0.5 %), Fe-citrate 0.5 %) FeEDTA (0.1 % 0.2 %) were sprayed 4th 5th leaves apex twig. And after 1 week spraying, observation various parameters recorded. Improvement plant like chlorophyll content index (CCI), photosynthetic rate (P n), stomatal conductance (g s) intercellular CO2 conc. (C i) recorded best with application 1.0 % both treated untreated upper leaves. The maximum recovery such as total leaf content, superoxide dismutase (SOD) peroxidase (POD) activity also noted Fe-sulphate. However, 0.5 % had similar for under study. ability induce responses deficient plants following order Fe-sulphate>Fe-citrate>FeEDTA. Differential exhibited by regard sources. Among cultivars, Saharanpur Prabhat responded followed Pratap.
