The characterized by Fourier Transform Infrared (FT-IR), scanning electron microscopy (SEM), transmission (TEM), UV–visible and X-ray diffraction (XRD). These green (NPs) were used mitigating adverse effects salinity on seed germination growth parameters in plants. Accordingly, two experiments conducted. first experiment, seven concentrations NPs nine levels NaCl:CaCl apptoed seeds germination, their evaluated. second three NaCl hypothesized to affect plant parameters. Seed height, leaf, root fresh dry weights, as well relative water content (RWC), decreased significantly under salt stress. However, intervened alleviating beneficial due (1) activation antioxidant system enhancing enzymes such catalase (CAT), ascorbate peroxidase (APX), (POD), superoxide dismutase (SOD); (2) increase amounts proline, soluble sugars carbohydrates osmoprotection; (3) improvements flavonoid anthocyanin contents. Real-time PCR showed that contents increased because higher expressions chalcone synthase ( CHS ), flavanone 3‐hydroxylase F3H anthocyanidin ANS ) genes. conclusion, offered application further research agricultural development.

Nano-Management Approaches for Salt Tolerance in Plants under Field and In Vitro Conditions

Agronomy, Journal Year: 2023, Volume and Issue: 13(11), P. 2695 - 2695

Published: Oct. 26, 2023

Soil salinity is a serious global problem that threatens high percentage of the soils. Salinity stress can create ionic, oxidative, and osmotic stress, along with hormonal imbalances, in stressful plants. This kind was investigated on agricultural productivity at different levels, starting vitro (plant tissue culture), through hydroponics, pots, field conditions. Several approaches were studied for managing including using traditional materials (e.g., gypsum, sulfur), organic amendments compost, biochar, chitosan), applied manufactured or engineered nanomaterials (NMs). Application ameliorating has gained great attention due to their efficiency, eco-friendliness, non-toxicity, especially biological nanomaterials. The application NMs did not only support growing plants under but also increased yield crops, provided an economically feasible nutrient management approach, environmentally robust sustainable crop productivity. Nano-management may involve applying nano-amendments, nanomaterials, nano-enabled nutrients, nano-organic amendments, derived smart nanostructures, nano-tolerant plant cultivars. Producing cultivars are tolerant be achieved conventional breeding plantomics technologies. In addition large-scale use there urgent need address treat nanotoxicity. study aims contribute this area research by exploring nano-management current practices raises many questions regarding expected interaction between toxic effects such includes whether acts positively negatively cultivated soil activity, what regulatory ecotoxicity tests protocols should used research.

Application of the salt stress to the protoplast cultures of the carrot (Daucus carota L.) and evaluation of the response of regenerants to soil salinity

Plant Cell Tissue and Organ Culture (PCTOC), Journal Year: 2019, Volume and Issue: 137(2), P. 379 - 395

Published: Feb. 15, 2019

This is the first study to generate carrot plants for enhanced salinity tolerance using a single-cell in vitro system. Protoplasts of three accessions were exposed treatment by seven different concentrations NaCl (10–400 mM). Salt higher than 50 mM decreased plating efficiency and those 200–400 completely arrested mitotic divisions cultured cells. The protoplast-derived from control 50–100 subjected an 8-week salt stress greenhouse conditions induced salinized soil (EC 3 6 mS cm−1). applied polyploidy among regenerated plants. regenerants obtained 100 NaCl-treated protoplast cultures grown saline had survival rate compared cultures. salt-stressed accumulated anthocyanins petioles produced denser hairs on leaves comparison influenced pollen viability seed setting regenerants. results suggest that creates variation which allows alleviating negative effects development reproduction carrot. protoplasts generates variability manifested differences cellular response ploidy. adaptation was associated with accumulation increased hairiness.
