Abstract
Nanoparticles affects growth and development of Plant. Zinc is an important micronutrient that regulates various physiological responses in plant. Application of nanoparticles for modulating plants physiological response is a recent practice. Zinc nanoparticles has been widely used in industry for several decades. However, no significant work had been made on its potential use in agriculture. Understanding physiological effect of Zn NP on rice seed germination could suggest the basis for its prospective application in agriculture to improve plant growth. In the present experiment effect of Zn NP was studied in Kmj-6-1-1 which is a commonly growing rice cultivar of Karimganj district of Assam, India. An exposure to Zn NP (0 mg/L, 5mg/L,10mg/L, 15mg/L, 20mg/L & 50mg/L) caused significant changes in radicle and plumule length , mass ( fresh & dry mass) and seed moisture content in rice. Antioxidant enzymes like guaiacol peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD) and gluthathione reductase (GR) also increased due to ZnNP treatment. This suggest that Zn NP may significantly alters antioxidant metabolism during rice seed germination. In conclusion, Zn NP protected rice plants from ROS damage by improving levels of antioxidant enzyme activities during germination. As a consequence the Zn NP treated seeds, showed better potential for germination. Further, genomic analysis of germinating rice seeds are needed to elucidate the molecular mechanisms by which Zn NP modulates germination process in rice.
