BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: April 5, 2024

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).

Evaluation of Salinity Tolerance Threshold of Two Wheat Cultivars Via Photosynthetic Efficiency and Ion Homeostasis

Deleted Journal, Journal Year: 2025, Volume and Issue: 77(1)

Published: Jan. 31, 2025

Abstract The possible growth and production of wheat have been negatively influenced by salinity stress, which is a critical environmental factor. Therefore, our study aimed to determine the tolerance threshold two cultivars (Amin Barzegar) via photochemical efficiency ion homeostasis under eight levels (0.5, 2, 4, 6, 8, 10, 12, 14 dS m −1 ) using completely randomized design with three replicates. Both experienced decrease in investigated leaf area from 2 level, shoot root dry weight trends remaining unchanged until 6 followed change trends. Some significant interactions between stress were found photosynthetic pigments chlorophyll fluorescence parameters. Increasing reduced F v /F , 0 YPII both cultivars. However, increase non-photochemical quenching (NPQ) was observed as intensity increased. NPQ approximately 30% lower Barzegar than that Amin severe stress. antioxidant enzyme activity, K + concentration, /Na ratio cultivar remarkably higher those Amin; meanwhile, maintained Na concentration Accordingly, photosynthesis parameters, redox, ionic be linked tolerance, recognized sensitive (salt’s threshold: 3.67 tolerant 7.13 cultivars, respectively. some such Barzegar, could manage improving activities, maintain when raised.

Assessing Growth Performance and Agrometeorological Indices of Matricaria chamomilla L. Governed by Growing Season Length and Salicylic Acid in the Western Himalaya

Horticulturae, Journal Year: 2025, Volume and Issue: 11(5), P. 485 - 485

Published: April 30, 2025

German chamomile (Matricaria chamomilla L.) is a suitable medicinal and aromatic crop to cultivate in diverse regions, but its relationship with weather major concern evaluating the development production Western Himalayan region. Thus, field experiment was executed for two years (2018–2019 2019–2020) at CSIR-Institute of Bioresource Technology, Palampur, India, evaluate studies different phenological phases under acidic soil conditions mid hills Himalaya. Agrometeorological indices were worked out four sowing times from 20 November January foliar application elicitor, i.e., salicylic acid three levels (viz., SA0: 0 mg/L, SA1: 25 SA2: 50 mg/L). The results revealed that number days required attaining each stage decreased delay time. Higher growing degree (GDDs), photothermal units (PTUs) heliothermal (HTUs) accumulated early showed gradual decrease delayed sowing. Salicylic produced significant effect on accumulation agrometeorological indices, irrespective applied doses, irregularity. GDDs, PTUs, HTUs associated higher flower essential oil yield; thus, are chamomile.

Published: Dec. 5, 2024

Seed priming is a state-of-the-art, low-cost, and environment-friendly strategy to improve seed germination, vigor, abiotic biotic stress tolerance, the yield of field horticultural crops. involves imbibing seeds in solution under desired set environmental conditions for period followed by drying before radicle protrusion. Several approaches including hydropriming, osmopriming, bio-priming, hormonal priming, nutrient nanoparticle electropriming can be effectively employed different crop growth resilience. known trigger enzymatic, hormonal, physiological, transcriptomic, metabolomic, proteomic regulations embryos during germination plant growth, which leads faster synchronized higher tolerance plants. Furthermore, induce cross-tolerance between stressors memory resilience next generation stresses. The present review paper discusses applications underlying biochemical, molecular mechanisms priming. we discuss current challenges/bottlenecks widespread application production.
