“…In rice, the number of AC-DCs per root tip increased by up to 43% in response to NaCl (60 mM) treatment in the salt-tolerant Pokali variety but not in the salt-sensitive IR29 variety. The thickness of the mucilage layer surrounding the AC-DCs remained unchanged in Pokali but was decreased by 35% in IR29 in response to salt stress [ 85 ]. The authors concluded that, together with root growth parameters, AC-DCs represented a promising cellular marker for the screening of salt stress tolerant rice varieties.…”

The root extracellular trap (RET) consists of root-associated, cap-derived cells (root AC-DCs) and their mucilaginous secretions, and forms a structure around the root tip that protects against biotic and abiotic stresses. However, there is little information concerning the changes undergone by the RET during droughts, especially for tree species. Morphological and immunocytochemical approaches were used to study the RET of black poplar (Populus nigra L.) seedlings grown in vitro under optimal conditions (on agar-gelled medium) or when polyethylene glycol-mediated (PEG6000—infused agar-gelled medium) was used to mimic drought conditions through osmotic stress. Under optimal conditions, the root cap released three populations of individual AC-DC morphotypes, with a very low proportion of spherical morphotypes, and equivalent proportions of intermediate and elongated morphotypes. Immunolabeling experiments using anti-glycan antibodies specific to cell wall polysaccharide and arabinogalactan protein (AGP) epitopes revealed the presence of homogalacturonan (HG), galactan chains of rhamnogalacturonan-I (RG-I), and AGPs in root AC-DC cell walls. The data also showed the presence of xylogalacturonan (XGA), xylan, AGPs, and low levels of arabinans in the mucilage. The findings also showed that under osmotic stress conditions, both the number of AC-DCs (spherical and intermediate morphotypes) and the total quantity of mucilage per root tip increased, whereas the mucilage was devoid of the epitopes associated with the polysaccharides RG-I, XGA, xylan, and AGPs. Osmotic stress also led to reduced root growth and increased root expression of the P5CS2 gene, which is involved in proline biosynthesis and cellular osmolarity maintenance (or preservation) in aerial parts. Together, our findings show that the RET is a dynamic structure that undergoes pronounced structural and molecular remodeling, which might contribute to the survival of the root tip under osmotic conditions.

“…The best results were shown by the Pokkali variety in plant height (184.13 cm), root length (25.68 cm), root wet weight (91.75 g), and root dry weight (16.24 g) (Table 3). The saline conditions the root growth of Pokkali varieties is better than IR29 varieties [39]. According to its description, the Pokkali variety reaches 160-200 cm in height, Biosalin 2 Agritan variety 109 cm, while IR 29 variety 100 cm [40].…”

The study for investigate the level production and growth for several varieties of paddy rice on washed saline land with microbial consortium treatment. The environmental design used factorial Randomized Group Design. The microbial consortium application (no microbial application, microbial application A, microbial application B, microbial application C), while the second factor of paddy rice varieties (Pokkali, Biosalin 2 Agritan, IR 29) and repeated three times. The data obtained were analyzed with the F test. If significantly different, then further test was conducted using DMRT 5%. The results showed that bleaching using fresh water decreased the value of electrical conductivity. The interaction between the treatment of the type of microbial consortium and the variety of paddy rice did not affect all observed variables, but the application of the type of microbial consortium independently differed between treatments on the growth component, namely the variable plant height and the best yield shown by Pokkali, while the production component had no effect. The treatment of the type of paddy rice varieties differed between treatments on both growth and production components and the best was Biosalin 2 Agritan of 5.80 tons.ha−1, IR 29 4.37 tons.ha−1, and Pokkali 2.96 tons.ha−1.

“…There are many crops with low salinity tolerance including rice (Oryza sativa L.) that has been observed to be highly susceptible to the rhizosphere salinity than other cereals [ 18 ]. From rice, it has been observed that high sensitivity mainly occurs at the vegetative and reproductive stages [ 19 ].…”

Direct utilization of treated effluent from natural treatment systems for irrigation can be challenging on sensitive plants due to high levels of salinity. Post-treatment of such an effluent prior to its applicability in irrigation can be of significant importance. In this study, the wastewater from a natural treatment plant was treated using a lab-scale filtration system with zeolite as a filter material. Three different column depths (0.5 m, 0.75 m, and 1 m) were used to investigate the effect of column depth on the treatment efficiency of the media. The suitability of the raw wastewater and the treated effluent from each column for irrigation purposes was investigated. The water quality parameters investigated were; electrical conductivity (EC), total dissolved solids (TDS), sodium (Na+), calcium (Ca2+), and magnesium (Mg2+). From the analysis results, it was observed that the column depth had a significant influence on the removal efficiency of the pollutants. The highest removal efficiency (94.58%) was achieved from the combination of electrical conductivity and 1 m column depth, while the lowest removal efficiency (10.05%) was observed from the combination of calcium and 0.5 m column depth. The raw wastewater fell mostly into a “very high” hazard, which is class four (C4) based on electrical conductivity and class four (S4) based sodium adsorption ratio; making it unsuitable for irrigation purposes. However, when the wastewater was subjected to 1 m column depth, the quality of the treated effluent improved significantly which in turn also improved the suitability of the effluent for irrigation purposes, with percent compliance ranging from 20.19% to 97.54%.
