137 Effect of Different Pre-Sowing Seed Treatments on Germination of Some Cassia Species
By : M.R. Khan
Abstract : Pterocarpus marsupium Roxb. economically and medicinally important species. The seeds of P. marsupium shows poor germination and plant stand. Among the different treatments tried to enhance the germination potential of seeds the treatment with H2SO4 15 minutes, scarification by sand paper technique and treatment with GA3 500 ppm were found most effective and overall germination percentage increased significantly as compared to control. Treatment with hot water also given satisfactory results.

166 The effect of rare earth substitution on the structural and magnetic properties of ZnFe2-xNdxO4
By : Nidhi Sharma, Sushil Kumar and P. Aghamkar
Abstract : Polycrystalline ferrite samples of ZnFe2-X NdxO4 (Where x = 0.025, 0.050, 0.075, 0.1) system were synthesized by co-precipitation methods. The present work is focused on the synthesis and characterization of Zinc ferrite nanocrystals and their subsequent as an attempt to modify the structural and magnetic properties. The samples were characterized by XRD, FTIR, TEM and VSM techniques. The influence of small substitution of iron with rare-earth ions in Zinc ferrites has been investigated.
