However, it has become essential to understand the ideal environmental conditions that can maximize AMF benefits in crop yield and soil health as a valuable biofertilizer. Accordingly, a comprehensive ecological study of AMF in black pepper (<em>Piper nigrum</em> L.) fields was conducted. The study aimed to identify AMF diversity and population characteristics over a broad area of black pepper fields in Kerala, South India, and to analyse various factors influencing AMF symbiosis in crops. It also focused on identifying the agroclimatic, soil, and crop influencers that impact mycorrhizae in traditional crop fields. Altogether, nine genera and 29 AMF species are identified from the randomly sampled black pepper fields (of diverse varieties of the crop) that belong to two different soil orders and 13 different soil series in the region. Among them, three genera and 22 species were new reports from black pepper. <em>Acaulospora laevis</em> and <em>Funneliformis badius</em> were the most commonly found species. Seasonal analysis showed a significant increase in spore density during the monsoon season, while root colonization exhibited varying patterns. Correlational studies and principal component analysis enabled the identification of specific soil and plant factors individually and in combinations influencing mycorrhizal activities. Overall, the study underscores the significance of ecological research on AMF symbiosis in specific crops and specific soil systems.</div></div>","PeriodicalId":15136,"journal":{"name":"Journal of Applied Research on Medicinal and Aromatic Plants","volume":"45 ","pages":"Article 100617"},"PeriodicalIF":3.8,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 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.

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.
