EFFECT OF COPPER NANOPARTICLES ON IN-VITRO SEED GERMINATION OF WHEAT (TRITICUM AESTIVUM L.) VARIETIES
AbstractThe comparative study of in-vitro seed germination was conducted to determine the influence of different concentrations of chemically synthesized copper nanoparticles (CuNPs) on the in-vitro seed germination and growth of two different varieties of wheat- PBW677 and PBW725 on MS medium. For all growth parameters taken under the present study, PBW 725 variety of wheat performed better in the basal MS media having different concentration of CuNPs than PBW 677. 100% germination percentage of PBW 725 variety of wheat is achieved on Basal MS medium supplemented with 5 ppm CuNPs. This variety has better seed vigour and tolerance index. It indicates that a lower concentration of CuNPs is potential enhancer of seed germination of this particular variety. But the higher concentration of the nanoparticles proved to be detrimental and resulted into poor seed germination and decreased morphological development of the plants of both varieties.
