Exogenous melatonin alleviates salt stress by improving leaf photosynthesis in rice seedlings.

Plant physiology and biochemistry : PPB, 2021
Melatonin (MT), an important antioxidant existing in plants and animals, has been widely reported to participate in the process of plants coping with stress.

Melatonin enhances Na+/K+ homeostasis in rice seedlings under salt stress through increasing the root H+-pump activity and Na+/K+ transporters sensitivity to ROS/RNS

, 2021
Salinity stress is one of the most serious factors limiting the productivity of crops. Rice at the seedling stage is extremely sensitive to salt. Studies have shown that melatonin can improve plant resistance to a variety of abiotic stresses, including ...

Phytotoxicity of Thiocyanate to Rice Seedlings

Bulletin of Environmental Contamination and Toxicology, 2012
The acute toxicity of potassium thiocyanate (KSCN) and ammonium thiocyanate (NH(4)SCN) to rice seedlings was tested. Hydroponically-grown plants showed different responses to the two species of thiocyanate. NH(4)SCN caused more severe stress to rice seedlings than KSCN.

Puddled Soil and Rice Seedling Characteristics Affecting Rice Seedling Withdrawal Force

Transactions of the ASAE, 1989
ABSTRACT THE effect of puddled soil and rice seedling characteristics on the rice seedling withdrawal force was determined in a laboratory study. Rice seedling withdrawal force is a good index of seedling anchorage in puddled soil. The goal of this study was to obtain fundamental information on rice seedling and puddled soil characteristics needed for ...

Morphogenesis of Rice and Arabidopsis Seedlings in Space

Journal of Plant Research, 1999
Seedlings of rice (Oryza saliva L.) and Arabidopsis (A. thaliana L.) were cultivated for 68.5 hr in the RICE experiment on board during Space Shuttle STS 95 mission, and changes in their growth and morphology were analyzed. Microgravity in space stimulated elongation growth of both rice coleoptiles and Arabidopsis hypocotyls by making their cell walls ...

Polystyrene microplastics enhanced the toxicity of cadmium to rice seedlings: Evidence from rice growth, physiology, and element metabolism.

Science of the Total Environment
Microplastics (MPs) and cadmium (Cd) are toxic to rice; however, the effects and mechanisms of their combined exposure are unclear. The combined exposure effects of polystyrene microplastics (PS-MPs) with different particle sizes (1-10 μm, 50-150 μm) and

Application of TiO2 nanoparticles to reduce bioaccumulation of arsenic in rice seedlings (Oryza sativa L.): A mechanistic study.

Journal of Hazardous Materials, 2020
The possible application of TiO2 nanoparticles (nano-TiO2) to alleviate arsenic bioaccumulation in rice seedlings and such a functioning with their crystalline structure were investigated.

Variation in the nitrate reductase of rice seedlings

Planta, 1972
Nitrate reductase was induced in rice seedlings by nitrate and by chloramphenicol. During the induction period the different enzyme activities associated with nitrate reductase increased to different degrees. Nitrate induced high NADH-nitrate reductase activity and a great increase in the NADH-cytochrome c reductase activity which was associated with ...

Dissemination of weeds with rice seedlings

Tropical Pest Management, 1988
Abstract Dissemination of weed seeds, weed seedlings, and shoots of perennial weeds along with transplanted rice (Oryza sativa L.) seedlings was observed in farmers’ fields in Guimba, Nueva Ecija, Philippines. The percentage of weed seedlings and shoots in bundles of rice seedlings to be transplanted into the field ranged from 4–5 to 14.2% in the wet ...

Microplastic particles increase arsenic toxicity to rice seedlings.

Environmental Pollution, 2019
Hydroponic experiments were conducted to study the effects of microplastic particles of polystyrene (PS) and polytetrafluoroethylene (PTFE) on arsenic (As) content in leaves and roots of rice seedlings, and the changes in root vigor and physiological and
