    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.
