Grain legumes are a rich source of dietary proteins and hence essential for achieving food nutritional security, worldwide. negatively affected by salt stress, which results in decreased growth, yield, productivity, other financial losses. Salt stress causes severe phytotoxicities, like specific ion toxicities, hormonal imbalances, disruptions stomatal conductance, alterations leaf water potential rate photosynthesis. To enhance agricultural productivity under conditions, several ecofriendly methods have been tried recently. Out these, the use biostimulants gained particular attention due to their ease availability high-stress ameliorative potential. It includes non-microbial humic acid seaweed extracts (SWE), as well microbial mycorrhiza, plant growth-promoting nitrogen-fixing bacteria, promote growth development. Biostimulants successfully alleviate stress-induced toxicities legumes, when introduced either alone or combination with macro- microorganisms soil. In response salinity, plants raise cellular levels osmolytes (proline glycine betaine) polyamines, phytohormones. The application grain alleviates toxicity improving seed germination, seedling photosynthesis, nitrogen fixation, absorption uptake minerals, development, ROS homeostasis osmoregulation. Many reviews lacked assessment effect these on mitigation legumes. development integrated, eco-friendly sustainable various mode action managing legume production is discussed present review.

Опубликована: Ноя. 1, 2023

Plants face abiotic stressors, such as extreme temperatures, drought, salinity, flood, and heavy metals, which negatively impact their growth development, leading to lower agricultural productivity, food security concerns, financial losses. Nanotechnology has emerged a solution mitigate these negative effects, improving resource use efficiency, reducing pollution, preventing plant diseases, enhancing sustainability. Nanoparticles (NPs) addresses nutrient deficiencies, enhance stress tolerance, improve crop yield quality. Sustainable environment friendly methods for synthesizing NPs have been developed over the last few decades. possess distinct qualities can serve powerful sensors, controlling critical physiological biochemical processes in plants. Furthermore, offer unique mechanisms adapting changing climatic conditions. Abiotic generates reactive oxygen species (ROS), cause oxidative impairs redox homeostasis.

Abstract Pea ( Pisum sativum L.), a globally cultivated leguminous crop valued for its nutritional and economic significance, faces critical challenge of soil salinity, which significantly hampers growth production worldwide. A pot experiment was carried out in the Botanical Garden, The Islamia University Bahawalpur to alleviate negative impacts sodium chloride (NaCl) on pea through foliar application ascorbic acid (AsA). Two varieties Meteor (V1) Sarsabz (V2) were tested against i.e. 0 mM NaCl (Control) 100 NaCl. Three levels (Control), 5 10 applied spray. experimental design completely randomized (CRD) with three replicates. Salt stress resulted suppression growth, photosynthetic activity, yield attributes plants. However, AsA treatments effectively alleviated these inhibitory effects. Under conditions, treatment led substantial increase chlorophyll (41.1%), chl. b (56.1%), total contents (44.6%) carotenoids (58.4%). salt stress, there an Na + accumulation, lipid peroxidation, generation reactive oxygen species (ROS). increased proline (26.9%), endogenous (23.1%), soluble sugars (17.1%), phenolics (29.7%), enzymatic antioxidants SOD (22.3%), POD (34.1%) CAT (39%) both under stress. Salinity reduced while foliarly pod length (38.7%), number pods per plant (40%) seed weight (45.2%). To sum up, salt-induced damage plants by enhancing pigments, non-enzymatic activities, maintaining ion homeostasis, reducing excessive ROS accumulation limitation peroxidation. Overall, V2 (Sarsabz) performed better as compared V1 (Meteor).

Abstract Canola, a vital oilseed crop, is grown globally for food and biodiesel. With the enormous demand growing various crops, utilization of agriculturally marginal lands emerging as an attractive alternative, including brackish-saline transitional lands. Salinity major abiotic stress limiting growth productivity most causing insecurity. Salicylic acid (SA), small-molecule phenolic compound, essential plant defense phytohormone that promotes immunity against pathogens. Recently, several studies have reported SA was able to improve resilience withstand high salinity. For this purpose, pot experiment carried out ameliorate negative effects sodium chloride (NaCl) on canola plants through foliar application SA.

Non-halophytic plants are highly susceptible to salt stress, but numerous studies have shown that halo-tolerant microorganisms can alleviate this stress by producing phytohormones and enhancing nutrient availability. This study aimed identify evaluate native microbial communities from salt-affected regions boost black gram (Vigna mungo) resilience against salinity, while improving plant growth, nitrogen uptake, nodulation in saline environments. Six soil samples were collected a region eastern Uttar Pradesh, revealing high electrical conductivity (EC) pH, along with low A total of 72 bacterial strains isolated 28 root nodules, 32 the bacteria tolerating up 10% NaCl. These characterized through taxonomic biochemical tests. Cross-compatibility analysis showed two rhizobia compatible five salt-tolerant bacteria. exhibited significant growth-promoting traits, including phosphate, potassium, zinc solubilization, as well ACC deaminase, IAA, siderophore, EPS production. Strain Paenibacillus sp. SPR11 strongest overall performance. Genetic diversity was assessed using BOX-PCR ERIC-PCR, identified 16S rRNA gene sequencing. In seed germination under conditions (200 mM 300 mM), co-inoculation Bradyrhizobium yuanmingense PR3 resulted enhancement (40%), growth (84.45%), shoot (90.15%) compared single inoculation B. PR3. Under greenhouse Leonard jars, significantly enhanced length, fresh dry biomass, nodule count, weight. Chlorophyll content, crude protein levels increased, proline content decreased uninoculated seeds. Our best understanding leads us believe is very first report utilizing PR3, demonstrating their promising potential enhance architecture, formation free conditions.
