Kadipani in Gujarat has large deposits of this ore. Open cast mining by GMDC has resultedin disturbed ecology. Earlier the efforts have been made by the forest department to grow tree species, in order to restore the forestecosystem, but the plants grew slowly and with stunted morphology and scanty survival. The obligate fungal symbionts known asarbuscular mycorrhizal fungi (AMF) present in plants play a key factor supporting plant growth in stressed conditions. Therefore, AMFstrains were first isolated from mining area and were used to raise the saplings first in polybags. Then after 75 days these were used forrevegetating the mine burdens or nearby waste land. The paper presents a pioneering efforts made to isolate and identify, the AMFfrom Fluorspar mines in Gujarat and then Glomus fasciculatum was incorporated in polybags filled with normal garden soil. Plants werealso raised by single spore inoculation method. Preliminary experiments revealed that the inoculated AMF strains promoted seedlinggrowth of Leuceana leucocephala and Millettia pinnata. The inoculation of AMF spores enhanced the growth of both the plants, and suchapplication can be used in sustainable restoration of the mining areas.

Abiotic stress alters the continuity between soil and plant atmosphere, reducing the yield of several essential crops.Abiotic stress now poses a considerable obstacle to plant development, and it will certainly worsen as desertification spreads acrossa larger section of the planet’s land area. The agriculture sector is significantly impacted by the weather and environment. Traditionalfarming methods and the food production required to sustain the nation’s growing population might be threatened by climate change.Improved cultivars created via breeding for a greater harvest index and disease tolerance were readily embraced during this periodof relatively consistent weather. Extreme climatic variability is projected due to climate change in this century. In many nations thatproduce crops, the agricultural climate will likely be warmer with more unpredictable rainfall, and stress spikes will be more severe. Tomaintain a growing population, agricultural productivity must be increased under more unfavourable environmental conditions. UsingGPS locators and climatic data from across the world, it is now feasible to comprehensively examine the genetic diversity in ancientlocal landraces to characterise the natural selection for local adaptation and to identify potential germplasm for tolerances to highstresses . With the use of candidate gene techniques and next generation sequencing, the physiological and biochemical componentsof these manifestations may be genomically examined. Wild relatives of crops possess practically untapped genetic diversity for abioticand biotic stress tolerances and may greatly improve the domesticated gene pools presently available as a survival omics strategy toassist crops endure the expected extremes of climate change. It is an issue to increase agricultural productivity in the face of climatechange. In order to achieve this, it is necessary to combine a number of disciplines, including eco-geographical assessments of geneticresources, modern advances in genomics, agronomy, and farm management, all of which are backed by knowledge of how genotypeenvironmentinteraction affects crop climate adaptability.","PeriodicalId":14298,"journal":{"name":"INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT","volume":"109 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89013414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollens are sensitive to environmental conditions and quickly lose their viability after anthesis. In vitro storage potential of pollen grains depends on species, genotype, flower type, and storage conditions. The present study's objective was to evaluate pomegranate germplasm's storage potential and to study germination media's influence on short-term stored pollen's germination percentage. Pollens of fifteen pomegranate genotypes were collected and stored at 4 °C for 30 days. Pollen viability was assessed using in vitro pollen germination by the agar-Petri method. The germination media was composed of different concentrations of sucrose, boric acid, and agar. The results showed that germination media (12.5% sucrose + 0.2% agar) supplemented with 10 ppm boric acid gave the highest germination among all cultivars. Among genotypes, maximum (58.3%) germination was observed in Desi and Kandhari red pollens, and minimum (16.3%) was observed in Sandhora. The concentration of boric acid in germination media influenced pollen germination. The highest pollen germination was found at 10 ppm, followed by 5 ppm, and the lowest germination was found in media with no boric acid. Conclusively genotypes show variation in storage potential, and germination media influences post-storage germination rate. The utilization of effective germination media can increase the pollen germination rate for pomegranate genotypes.","PeriodicalId":14298,"journal":{"name":"INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81850785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These samples were taken to the laboratory for assessment of various chemical parameters. Calcium found to be highly significant (p 0.001), total hardness, chemical oxygen demand (COD) and biological oxygen demand (BOD) identified as significant (p 0.05) while other parameters i.e., total dissolved solids (TDS), electrical conductivity (EC), pH, turbidity, Chlorine (Cl), nitrate (NO3), salinity, magnesium (Mg), iron (Fe), lead (Pb) and cadmium (Cd) revealed no significant (p0.05) co-relation.   The results indicated that all the parameters had significant spatio-temporal variations during June due to low rain falls which as result higher contaminant concentrations. Whereas during September there were higher flooding due to monsoon rains, consequently the contaminants were found in diluted concentrations.
