It is commonly employed in the treatment of depression, epilepsy, and Alzheimer's disease due to its significant medicinal and aromatic properties. However, the genetic diversity of wild <em>A. tatarinowii</em> resources has declined due to over-exploitation and habitat destruction. This study aims to assess the genetic diversity of the natural populations of <em>A. tatarinowii</em>, establish a core germplasm bank, explore its genetic richness and uniqueness, prevent genetic erosion, and identify beneficial genes. In this study, for the first time, 429A. tatarinowii samples from 40 populations were analyzed for genetic diversity and population structure using Hyper-Seq technology. A total of 4772,850 high-quality Single Nucleotide Polymorphisms (SNPs) and 1563,000 Insertions and Deletions (InDels) variant loci were identified, with C/T as the predominant variant type and a Ts/Tv ratio of 1.079. Annotation of these loci indicated that the majority of variants occurring in intergenic regions, accounting for 50.59 % of the total. Moreover, the heterozygosity, nucleotide diversity, and FST of <em>A. tatarinowii</em> suggested low genetic diversity within this species within the populations. The analysis of molecular variance (AMOVA) revealed that the population variation of <em>A. tatarinowii</em> is mainly caused by the variation between populations (72.06 %), while the variation within populations only contributes a small part (27.94 %) Through NJ tree, PCA, and ADMIXTURE analyses, the 429<em>A. tatarinowii</em> samples were classified into five subgroups, with some genetic exchange observed. A total of 7163 high-quality polymorphic SNPs were identified, and a core germplasm consisting of 85 samples was established, achieving genotype retention rates similar to those of the original germplasm. This indicates that a smaller number of germplasm resources can effectively represent the majority of the genetic diversity. Additionally, PCA analysis further confirmed the representativeness and validity of the constructed core germplasm resources. Furthermore, the DNA fingerprints of the 429 accessions were established using the most effective combinations of 26 SNP markers, which served as specific markers to effectively distinguish all samples. In conclusion, these findings offer valuable insights into the genetic structure of <em>A. tatarinowii</em>, facilitating the identification of high-quality genes and providing a scientific foundation for the development of breeding programs and conservation strategies for <em>A. tatarinowii</em>.</div></div>","PeriodicalId":15136,"journal":{"name":"Journal of Applied Research on Medicinal and Aromatic Plants","volume":"44 ","pages":"Article 100605"},"PeriodicalIF":3.8,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142723020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the important phenological growth stages of karonda occurring during an annual growth cycle were identified and described using a three- digits extended BBCH (Biologische Bundesantalt, Bundessortenamt und Chemische Industrie) scale. A total of 38 secondary growth stages encompassing the 7 principal growth stages were identified and described as per the BBCH scale. The seven principal growth stages identified include three vegetative stages (bud, leaf and shoot development), two flowering stages (inflorescence emergence and flower development) and two fruiting stages (fruit development and maturity). Besides, the physicochemical changes occurring during fruit development and maturity stages were studied. The fruit weight, total soluble solids and iron content increased gradually during fruit development stages starting from 701 stage and reaching maximum at the 819 stage. Further, the important insect pests were documented from 010 to 819 stages. The insect pests such as defoliator and shoot webber cum borer were belonging to the Sphingidae and Tortricidae families respectively, were most commonly observed. The detailed description of phenological stages based on BBCH scale, information of physicochemical changes and insect pests generated in this study will help for scientific cultivation of karonda especially in scheduling crop production and crop protection practices.

In this research, we found that 42 % of the seeds in <em>T. laxa</em> were plump, and 58 % were shriveled.

Plump seeds showed over 90 % germination at three different temperatures, whereas shriveled seeds had a 57 % germination percentage at 15/30 °C. Continuous darkness significantly reduced the germination percentage for both seed types. Although <em>T. laxa</em> seeds displayed some salt tolerance, high salt concentrations (0.6 mol/L NaCl) markedly decreased their germination percentage. Freshly mature seeds initially had a 99 % germination percentage. However, seeds stored at room temperature for 90 days nearly lost their viability.

However, there is limited information on biomass generation from the postharvest management of this cannabis strain and the development of value-added products. This study aims to address this gap by conducting a survey of local cannabis farms and evaluating the quantity of cannabis biomass by-product materials resulting from the production process. According to the survey, stems were the most abundant materials followed by leaves and roots. These by-products were subsequently gathered and examined for its chemical components. The results of proximate analysis highlighted that the dried leaves had a high protein content up to 19.27 %, the highest in three types of biomasses. The composition of fat, fibre, ash, and carbohydrates varies depending on the type of biomass. By using sequential extraction, it was found that the extraction yield of pectin in the leaf materials was as high as 13.82 %, and in the stem part, it was at 13.02 %. Meanwhile, cellulose was found in the highest proportion from the roots, at 83.77 %. Confirmation of the composition of polysaccharides using microarray profiling revealed that these biomasses contain various types of polysaccharides (pectin, cellulose, hemicellulose).
