Improvement of yield and grain quality by periodic cold plasma treatment with rice plants in a paddy field

Abstract

The application of cold plasma has attracted considerable attention in the field of agriculture. We examined the effects of plasma irradiation and treatment with plasma‐activated Ringer's lactate solution (PAL) on rice seedlings in a paddy field. Irradiation during the vegetative growth period increased seedling growth, panicle number, and grain yield. In contrast, treatment during the reproductive growth period had a negative or no effect. Moreover, treatment with PAL solution promoted the growth of the main stem, such as grain number and panicle weight, and grain quality, but the grain yield from the whole plant was decreased. The results suggest that cold plasma treatment of rice seedlings is effective for improving plant growth, grain yield, and grain quality.

Detection of NO3− introduced in plasma-irradiated dry lettuce seeds using liquid chromatography-electrospray ionization quantum mass spectrometry (LC-ESI QMS)

“…The growth improvement effect of plasma irradiation on plants has attracted considerable global attention 1 – 3 . Thus far, there have been pioneering studies on the improvement of germination and growth 4 – 19 , control of hormone balance between gibberellic acid (GA) and abscisic acid (ABA) in seeds 20 , 21 , and improvement of harvest characteristics 22 using plasma irradiation. Recently, molecular biological studies were conducted to elucidate the mechanisms underlying the biological effects of plasma irradiation 23 .…”

Application of a Structured Water Generator for Crop Irrigation: Structured Water, Drought Tolerance, and Alteration of Plant Defense Mechanisms to Abiotic Stressors

“…The underlying mechanisms for improving drought tolerance and/or disease resistance will involve more advanced basic and applied research into seed and structured water treatments and their interactive effects on animal and plant health [13, 20-21, 28, 31-33]. Different forms of structured water have been studied for decades under other water research [77][78][79][80][81][82].…”

“…In the future, these liquids could be used in the clinic. Some of the solutions used to generate plasma-treated liquids (PTL) include water [59], culture media [247], Ringer's lactate [249], phosphate buffer saline (PBS) solution [250], Ringer's solution, and bicarbonate Ringer's solution [250]. Long-lived species of PTL components (namely, H 2 O 2 and NO 2 − ) show strong synergy with tumor suppressor enzymes, which are located on the cell membrane.…”
