Abstract Background The frequency and severity of abiotic stress events, especially drought, are increasing due to climate change. plant root is the most important organ for water uptake first be affected by limitation. It therefore becoming increasingly include traits in studies on drought tolerance. However, phenotyping under field conditions remains a challenging task. In this study, plants were grown hydroponic system with polyethylene glycol as an osmotic stressor sand pots examine eleven spring barley genotypes. anatomy two genotypes different response was investigated microscopically. Results Root diameter increased significantly ( p < 0.05) treatment 54% but decreased 12% pots. Polyethylene tip (51%) reduced elongation zone (14%) compared control. Under stress, shoot mass showed higher correlation r = 0.30) condition than treated -0.22). Conclusion These results indicate that roots take up prevents further uptake. glycol-triggered unsuitable investigating morphology barley. architecture more comparable conditions.

Rice (Oryza sativa L.) exhibits differential responses to salt stress and salt shock in electron transfer efficiency

Plant Stress, Journal Year: 2024, Volume and Issue: 12, P. 100481 - 100481

The study of crop response to soil salinity has traditionally focused on the effects varying salt concentrations, with less attention given methodologies application. This research aimed elucidate differential impacts two distinct exposure methods photosynthetic characteristics rice. Plants subjected a gradual increase in experience stress, whereas those immediately exposed high levels encounter shock condition. Our findings revealed that rice plants accumulated comparable shoot Na+ under both stress and at 4 10 days after onset stress. No significant differences were observed steady-state rate electron transport (ETR). In contrast, markedly reduced relative variable fluorescence 'J' step (Vj), thereby enhancing probability an exciton transferring beyond primary quinone acceptor (QA−) (ΨEo). led notable activity leaf photosystem II (PSII), as evidenced by Performance Index absorption basis (PIabs), which was twice control group. mechanism is believed facilitate activation alternative metabolic pathways. Additionally, kinetic measurements light potential indicated improved initial induction ETR brief photosynthetically active radiation (PAR) compared control. effect not treatment results suggest exhibit physiological responses versus shock, positive influence during may have been previously underestimated.
