Canal irrigation water is scarce to aid agriculture; thus, a supplementary water supply requires accessibility from drainage water. In Pakistan, groundwater is brackish because of elevated levels of electrical conductivity (EC), residual sodium carbonates (RSC), and sodium adsorption ratio (SAR). But these waters can benefit well for irrigation during the primary phase of saline-sodic soil’s reclamation, if employing appropriate management practices, such as, chemical and organic amendments. A pot trial procedure ran under environmental conditions at the research area of the Department of Soil and Environmental Sciences, College of Agriculture, University of Sargodha, to assess the effect of sodic water with various amendments on sorghum and berseem fodder crops. The pot experiment comprised seven treatments, including T1 = Control having canal water with SAR 0.1 and EC 0.2 dS m-1 ; T2 = Sodic water with SAR 15; T3 = Sodic water (SAR 15) + Gypsum; T4 = Sodic water (SAR 15) + H2SO4; T5 = Sodic water (SAR 15) + compost; T6 = Sodic water (SAR 15) + FYM; T7 = Sodic water (SAR 15) + poultry manure, with three replicates under complete randomized design (CRD) by sowing sorghum “JS-88” and berseem “Hisar Berseem 1” cultivars taken from the Fodder Research Institute (FRI), Sargodha. The agronomic and fodder quality attributes were maximum in T3 treatment in sorghum compared with other concentrations and berseem. In both crops, mineral nutrients were variable, and nitrogen, phosphorus, and potassium were maximum in T5, compared with others.","PeriodicalId":21328,"journal":{"name":"Sabrao Journal of Breeding and Genetics","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44746264","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}

In Indonesia, three sexes of highland papaya exist with different telomere lengths, which protect chromosomes and deoxyribonucleic acid (DNA) from damage. Therefore, the purposeful study aimed to determine the telomere length, elemental composition, and phytochemical content of highland papaya leaves belonging to their different sexes. The telomere length observed and studied in said leaves (female, male, and monoecious) used the polymerase chain reaction (PCR) procedure. A scanning electron microscopy (SEM) analysis provided a more detailed material of leaves, while an energy dispersive X-Ray (EDX) helped observe elemental composition. Phytochemical content analysis ran by histochemical analysis. The results showed that the telomere lengths of young female, male, and monoecious leaves differed at 381, 391, and 396.66, respectively. According to the SEM analysis, nonsignificant differences occurred in the leaf surface of the three sexes of highland papaya leaves. Observation with EDX showed that sodium (1.98%) surfaced in female plant leaves; however, sodium and chlorine did not show in male plants. Monoecious leaves had sodium and chlorine at 0.88% and 0.28%, respectively. The histochemical analysis provided an overview of the distribution of flavonoids and tannins in young leaves of highland papaya. A discovery also noted the existence of both compounds in the adaxial and abaxial epidermis, mesophyll, xylem, phloem, sheath parenchyma, secretory cavities, and trichomes. The study concluded that sex affects telomere length, elemental composition, and the phytochemical content of highland papaya leaves. The study suggests that knowing the highland papaya’s sex is vital in plant breeding and genetics and could help improve plant health and productivity.","PeriodicalId":21328,"journal":{"name":"Sabrao Journal of Breeding and Genetics","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44848019","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}

Morphoanatomical changes in some medicinally important native species (Calotropis procera, Eclipta alba, Phyla nodiflora, and Ranunculus sceleratus) exposed to heavy industrial pollution gained evaluation. These species of choice were due to their widespread distribution in the area. Ten sites selected in the River Chenab, Chiniot, had three near point source pollution of Faisalabad industries within the 500-m radius (polluted) at three drains and two sites inside the river after each drain point source with the control site at 14 km after from the first industrial drain point source. The general response of all plants to effluents was growth retardation. Plant height increased significantly in all species from river sites. An increase in tallness was more prominent in species like C. procera and P. nodiflora. An increase in stem sclerification in C. procera and E. alba from polluted sites occurred, which indicated a better ability to tolerate industrial pollution. Remarkable increases in stem and leaf epidermis, intensive stem sclerenchyma, and closely packed stem vascular bundles in C. procera appeared, which could increase resistance to industrial pollution. Most of the morphoanatomical parameters notably attained a decrease in E. alba, the most vulnerable species. Plant survival depends on particular structural changes in dermal, mechanical, parenchymatous, and vascular tissues. Overall, industrial pollution adversely impacts plant morphological and micromorphological features, although the reaction of specific species to industrial contamination varies. The study determined that stem and leaf anatomical features, such as, epidermis size and storage tissue thickness, are suitable morphoanatomical markers for industrial pollution biomonitoring. Internal modifications of plants vegetating different industrial contaminated sites played a significant role in high tolerance levels.","PeriodicalId":21328,"journal":{"name":"Sabrao Journal of Breeding and Genetics","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45149314","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}
