“…Moreover, pea seedlings were affected by drought, which was observed in shoot and root growth as well as fresh and dry biomass accumulation. These findings align with prior research on peas [47,48]. Also, it was observed that drought conditions led to a decrease in shoot and root elongation rate as well as seedling vigor index in the control.…”

One of the main climate change-related variables limiting agricultural productivity that ultimately leads to food insecurity appears to be drought. With the use of a recently discovered nanopriming technology, seeds can endure various abiotic challenges. To improve seed quality and initial growth of 8-day-old field pea seedlings (cv. NS Junior) under optimal and artificial drought (PEG-induced) laboratory conditions, this study aimed to assess the efficacy of priming with three different nanomaterials: Nanoplant Ultra (Co, Mn, Cu, Fe, Zn, Mo, and Se), Nanoplant Ca-Si (Ca, Si, B, and Fe), and Nanoplant Sulfur (S). The findings indicate that nanopriming seed treatments have a positive impact on seed quality indicators, early plant growth, and drought resilience in field pea plants established in both optimal and drought-stressed conditions. Nevertheless, all treatments showed a positive effect, but their modes of action varied. Nanoplant Ultra proved to be the most effective under optimal conditions, whereas Nanoplant Ca-Si and Nanoplant Sulfur were the most efficient under drought stress. After a field evaluation, the examined comprehensive nanomaterials may be utilized as priming agents for pea seed priming to boost seed germination, initial plant growth, and crop productivity under various environmental conditions.

“…The aim of this research was to determine the molecular basis of osmotic stress tolerance in 7 field pea (Pisum sativum L.) varieties at the early seedling stage. A previous study of the effects of osmotic stress on germination and seedling growth of different field pea varieties (Petrović et al, 2021) showed that different concentrations of PEG in germination media significantly affect the seed germination of field pea. An increase in osmotic stress significantly decreased germination percentage (GP) in all the tested varieties.…”

Background: This study was carried out for an understanding of the antioxidant mechanisms of field pea varieties under osmotic stress conditions caused by a lack of water. The activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APx) and glutathione reductase (GR) were examined and analyzed. The gene expression levels of Cu/Zn SOD, cAPx and GR genes were also examined. Methods: Osmotic stress was stimulated using PEG 6000 with the osmotic potential of -0.1 MPa in 10 days old plant seedlings. The activity of the antioxidant enzymes was measured in the shoots and roots of pea seedlings. The gene expression levels of genes coding antioxidative enzymes were examined by the reverse transcription polymerase chain reaction (RT-PCR) technique. Arabidopsis 18S rRNA was used as endogenous control. Result: Osmotic stress changed the activities of antioxidant enzymes in the shoots and roots of pea seedlings. Varieties more tolerant to osmotic stress showed a significant increase in antioxidant activities in shoots and roots, while sensitive varieties showed a significant decrease. The results of the analysis of the expression of genes, coding for antioxidant enzymes, showed that the reaction of the tested cultivars to ROS was the result of increased expression of the tested genes in tolerant cultivars, i.e. decreased expression in sensitive cultivars.
