The production of medicinal plants under stressful environments offers an alternative to meet the requirements sustainable agriculture. action mycorrhizal fungus; Funneliformis mosseae and zinc in stimulating growth stress tolerance is intriguing area research. current study evaluated combined use nano-zinc fungus on physiochemical responses Dracocephalum moldavica salinity stress. employed a factorial based completely randomized design with three replications. treatments were different levels (0, 50, 100 mM NaCl), two mycorrhiza application (0 5 g kg− 1 soil), foliar spraying nano oxide 1000 ppm). Salinity decreased photosynthetic pigments content, SPAD value, chlorophyll fluorescence data (Fm, Fv, Fv/Fm). Plant dry weight, Na+ essential oil content significantly higher at 50 + co-application oxide. Electrolyte leakage increased salt stress, while inoculation compensated for trait. main constituents geranyl acetate, nerol, geranial, geraniol, viridiflorol, hexadecane, humulene, germacrene D. Energy metabolism demonstrates effectiveness treatment combinations promoting biosynthesis accumulation components. overall results more comprehensive field-based studies would be advisable extension section utilize marginal salty lands reliable valuable plant.

Salinity is a key devastating abiotic factor that hinders the development and yield of safflower. The sole combined application zinc oxide nanoparticles (ZnO-NPs) biofertilizer (BF) to improve salt tolerance in safflower has not been thoroughly explored. response plants pot experiment foliar spray ZnO-NPs alone combination with BF was thus detected. We determined ZnO-NP concentration 17 mg/L sufficient protect against salinity (250 mM NaCl) by increasing plant productivity, percent water content, osmolyte levels. Coapplication Phytoguard protected from stress improving activities antioxidant enzymes decreasing levels proline (leaves (61%) roots (63%)) malondialdehyde (MDA) (54%) (65%)). Under stress, Na

Plant response to silver nanoparticles: a critical review

Critical Reviews in Biotechnology, Journal Year: 2021, Volume and Issue: 42(7), P. 973 - 990

Published: Sept. 14, 2021

Although several metal ions/metal nanoparticles (NPs) are toxic to both plants and animals, some of them used as nutrients growth promoters. Plants exposed silver (Ag-NPs) have shown beneficial harmful effects. All concentrations Ag-NPs not effective for a given plant because any excess can block the passage essential nutrients. Regulated treatment by may enhance their overall development. It has been noticed that decrease mass edible (Cucurbita pepo, Allium cepa, cabbage, lettuce) vegetables, but they also induce germination seeds in many cases. NPs interact with proteins, enzymes, carbohydrates influencing total biomass, root, shoot plants. Also, act an ethylene inhibitor activate antioxidants onions. Their substantial quantity becomes deposited onion leaves bulbs. Size concentration two major factors responsible increase/decrease biomass. make adaptations reduce toxicity caused Ag-NPs. In cases, root elongation increase chlorophyll, carbohydrate, rate photosynthesis inhibit biosynthesis ethylene. This review article provides comprehensive overview adverse effects on germination, growth, development, physiological, biochemical characteristics wide range crop We critically discussed: chemistry, toxicity, uptake, translocation, accumulation systems.

Exogenous abscisic acid and jasmonic acid restrain polyethylene glycol‐induced drought by improving the growth and antioxidative enzyme activities in pearl millet

Physiologia Plantarum, Journal Year: 2020, Volume and Issue: 172(2), P. 809 - 819

Published: Oct. 23, 2020

Abstract Drought stress is one of the most immense and permanent constraints in agriculture, which leads to a massive loss crop productivity. However, little known about mitigation role exogenously applied abscisic acid (ABA) jasmonic (JA) pearl millet ( Pennisetum glaucum L.) under PEG‐induced drought stress. Therefore, current study investigated putative exogenous ABA JA improving tolerance millet. Thirteen‐day‐old seedlings were exposed six different treatments as follow; control (ck), PEG‐600 (20%), (100 μM), PEG+JA, PEG+ABA, data collected at 7 14 days after treatment (DAT). Results showed that PEG decreased plant growth while oxidative damage increased due over production H 2 O MDA content result activities antioxidative enzymes including APX, CAT, SOD leaves. positively enhanced profile by chlorophyll relative water treatment. A significant improvement was observed defense system resulting from PEG. Overall, performance found better than stress, future investigations are needed explore potential effects these phytohormones on long‐term management productivity
