- 摘要：A pot culture experiment has been carried out to find the extent of changes occurring in the biochemicals and nutrients of maize plants ( Zea mays L. ) grown under different concentrations of cobalt (50, 100, 150, 200, 250 mg kg -1 soil). The growth and yield parameters such as seedling vigour, number of cobs, number of seeds per plant; photosynthetic pigments viz., chlorophyll ‘a’, chlorophyll ‘b’, and total chlorophyll contents; biochemicals like total sugars ( reducing and non reducing), starch, amino acids and protein content and various macro- and micronutrients are determined 90 days after sowing (DAS). All the growth parameters, pigment content, biochemicals and mineral content increase at 50 mg Co kg -1 soil when compared with the control. Further increase in the Co levels (100-200 mg kg -1 soil) has a negative effect on all the above parameters.   Keywords: Cobalt; Growth; Zea mays ; Biochemicals; Nutrients. © 2009 JSR Publications.
