    Effect of cerium on seed germination and early seedling growth of wheat
    (University Of North Bengal, 2011-03) Shyam, Radhe; Aery, NC
    The effect of various concentrations of three species of cerium was studied on seed germination and early seedling growth of Triticum aestivum L. Seeds were germinated on moist filter papers added with 0.1, 0.5, 2.5, 12.5 and 62.5 Hg g' cerium as cerium chloride, cerium sulphate and cerium nitrate and observations were made on seed germination, shoot- root length, fresh and dry weight. Lower concentrations of cerium species significantly increased shoot-root growth and relative yield of seedlings. Higher concentrations (12.5 and 62.5 Hg g) proved to be toxic for seedling growth. The root growth was affected more adversely than shoots. Though germination speed was affected, ultimate germination was always 100 %. The results of this study indicate that low levels/ concentrations of cerium are beneficial for the test plants.

    Influence of tungsten and molybdenum on seed germination and early seedling growth of wheat - a comparative study
    (University of North Bengal, 2012-03) Kumar, Anil; Aery, NC
    Fifty one promising landraces of rice cultivars of three districts viz. Nadia, 24 Parganas(N) and MA comparative study on the effect of tungsten and molybdenum on seed germination and early seedling growth of wheat was carried out. Both W and Mo influenced the seedling growth in similar fashion. W and Mo enhanced the germination relative index at lower application. Relative yield increased at lower applied doses of W as well as Mo whereas at higher application it decreased. Lower applied doses of W and Mo showed maximum index of metal tolerance. Higher applied doses of both metals showed toxic effect on plant growth. A highly significant (p= 0.01 in W and p = 0.001 in Mo) increment in grade of growth inhibition (GG) at the higher administration of W and Mo was observed. The toxic effect of tungsten on wheat was more marked than molybdenum.

    Responses of Zn and Cd treatment in soybean and fenugreek
    (University of North Bengal, 2012-03) Aery, NC; Sarkar, S
    The effect of various doses of' zinc and cadmium on morpho-anatomical and physiological parameters of soybean and fenugreek was studied. High concentrations of both Zn as well as Cd resulted in chlorosis, necrosis, retardation of growth and reduction in leaflet size especially in soybean. A characteristic symptom was the formation of a red-brown pigment in the leaves, stem and roots. An increase in the phenolic contents was also observed with increasing Cd doses. The reasons for the formation of pigment have been explored.
