Liquid assisted pulsed laser ablation synthesized copper oxide nanoparticles (CuO-NPs) and their differential impact on rice seedlings.

Ecotoxicology and Environmental Safety, 2019
Hydroponic experiments were conducted to investigate impact of laser ablated copper oxide nanoparticles (CuO-NPs) on rice seedlings. The present work demonstrates that exposure of lower concentrations (5, 10, 20, and 50 µM) of CuO-NPs enhance growth (in ...

Excess copper inhibits the growth of rice seedlings by decreasing uptake of nitrate.

Ecotoxicology and Environmental Safety, 2019
Copper (Cu) toxicity has a deleterious effect on plant growth, and different nitrogen (N) forms have significantly different impacts on the uptake and accumulation of heavy metals by plants.

Rice seedlings release momilactone B into the environment

Phytochemistry, 2003
Since the growth inhibitor momilactone B was found recently in root exudates of rice (Oryza sativa L.), 3-day-old rice seedlings were transferred to hydroponic culture and the level of momilactone B released into the environment from the seedlings was measured.

Proteomic identification of rhythmic proteins in rice seedlings

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2011
Many aspects of plant metabolism that are involved in plant growth and development are influenced by light-regulated diurnal rhythms as well as endogenous clock-regulated circadian rhythms. To identify the rhythmic proteins in rice, periodically grown (12h light/12h dark cycle) seedlings were harvested for three days at six-hour intervals.

Effects of cerium oxide on rice seedlings as affected by co-exposure of cadmium and salt.

Environmental Pollution, 2019
Effects of CeO2 NPs (200 mg.L-1) on rice (Oryza sativa L.) alone or co-exposure with cadmium (Cd) and salt (sodium chloride, NaCl) were investigated in hydroponic systems for two weeks.

Effects of Graphene on Germination and Seedling Morphology in Rice

Journal of Nanoscience and Nanotechnology, 2015
The effects of graphene on the germination and growth of rice seeds were studied. Seeds were treated with graphene solutions at different concentrations. Obvious delaying effects on the germination rate were observed with the increasing of graphene concentration. The growth of radicle and plumule was inhibited.

Apigenin pretreatment enhances growth and salinity tolerance of rice seedlings.

Plant physiology and biochemistry : PPB, 2018
Soil salinity is a limiting factor in rice production. Since flavonoids present in most plant tissues play multiple roles in plant-environment interactions, in this study, we focused on the contribution of flavone aglycone (Apigenin) to the adaptation of

Effect of UV-B priming on the abiotic stress tolerance of stress-sensitive rice seedlings: Priming imprints and cross-tolerance.

Plant physiology and biochemistry : PPB, 2019
Ultraviolet (UV)-B priming can boost the abiotic stress tolerance of plants by activating stress-responsive pathways. The main objective of the present study was to investigate the persistence of priming imprints and cross-tolerance inducing effects of ...

Effects of organic molecules from biochar-extracted liquor on the growth of rice seedlings.

Ecotoxicology and Environmental Safety, 2019
There are many reports indicating that biochar can promote growth; however, its mechanism of action remains unclear. The aim of this study was to show that organic molecules from biochar-extracted liquor affect the growth of rice seedlings. In this study,
