Abstract
The aim of this research was to evaluate the potential application of nanocarbon in plant growth and physiological responses in rice plants. This research was designed to evaluate the effects of different concentration of nanocarbon (0-1,000 mg L-1) on growth characterizations and physiological parameters after 1-4 weeks of nanocarbon-treatment. Induction in the growth performances and contents of photosynthetic pigments (chlorophyll A, chlorophyll B and carotenoids), antioxidant enzyme activities (catalase and peroxidase) and flavonoids was observed in the rice plants after treated with nanocarbon. The results showed that nanocarbon promoted the plant growth in rice plants cv. Black jasmine rice or Hom-nin by increasing the shoot lengths and dry weights. The significant increase of shoot length and dry weight were found in 200 and 600 mg L-1 nanocarbontreatments. Additionally, the high contents of photosynthetic pigment concentrations in treated-plants showed significant difference at 600 mg L-1 nanocarbon compared to the control (0 mg L-1 nanocarbon). The antioxidant activities of catalase and peroxidase enzymes in nanocarbon treated-plants were significantly increased compared to the control. Furthermore, the induction of flavonoid contents in treated-plants was increased by 200 and 600 mg L-1 nanocarbon. The results suggested that nanocarbon able to promote the biomass and has benefit to increase the photosynthetic pigments and antioxidant enzymes for plant growth performances. This research provided plant growth and physiological responses evidence on the beneficial effect of nanocarbon in rice plants, especially Black jasmine rice or Hom-nin cultivar.
