“…According to the present study, there was a strongest positive correlation (P<0.001) between the leaf area and leaf width (r= 0.93) which is in consistent with the findings reported by Preethi et al (2018), followed by leaf length (r= 0.80) as well as between internodal length and petiole length (r= 0.60) (P<0.01). Leaf area showed a consistent relationship with the leaf width (Jayarathna et al, 2016).…”

The genetic variability in selected 21 black pepper accessions was analyzed based on desirable drought-tolerant and susceptible characteristics using principal component and cluster analyses. The experiment was conducted at ICAR-Indian Institute of Spices Research, Experimental farm, Peruvannamuzhi, Kozhikode using a randomized block design with four replications. Morphological, physiological and yield contributing traits were studied. The traits examined showed a comprehensive range of variability. The principal component and UPGMA clustering analyses were employed to assess the proportional contribution of various traits and grouped the genotypes, respectively. The first principal component was responsible for the highest variation (30.87%) in the yield-related characteristics, which were positively correlated with each other and correlated negatively with the morphological characteristics and stomatal frequency. Separate clusters were formed for the genotypes that displayed drought-tolerant characteristics (cluster 2 and 3) and those that showed susceptible characteristics (cluster 1). The results indicated that the analysed black pepper genotypes have significant genetic variability among them which may be helpful for identification of genotypes with desirable drought tolerant characteristics. Accessions 7211 (cluster 2), 1495, 1343 and 4132 (cluster 3) showed characteristics that make them potentially drought tolerant while the accessions 5717 and 4064 (cluster 1) showed drought susceptible traits.

“…This increased glycogenesis may result from enhancement of uptake of glucose from the liver and from the skeletal muscle by sensitization of insulin receptors and/or induction of the activity of enzymes involved in glycogen synthesis [ 86 ]. Preliminary screening carried out on Sri Lankan P. betle leaves revealed the presence of several phytochemicals as polyphenols, alkaloids, and steroids [ 87 , 88 ]. However, structure elucidation of antidiabetic compounds has not been reported to date.…”

The use of medicinal plant extracts and their isolated bioactive compounds for the management of diabetes mellitus has been tremendously increased in recent decades. The present study aimed at providing in-depth information on medicinal flora that has been widely used in the Sri Lankan traditional healthcare system for the management of diabetes mellitus. The data of this review article were obtained from published articles from January 2000 to September 2020 in scientific databases of PubMed, Web of Science, and Google Scholar. In this review, a total number of 18 medicinal plants with the antidiabetic activity were expressed, and their isolated antidiabetic active compounds were highlighted as new drug leads. Results of the reported studies revealed that medicinal plants exert a potent antidiabetic activity via both in vitro and in vivo study settings. However, bioactive compounds and antidiabetic mechanism (s) of action of many of the reported medicinal plants have not been isolated/elucidated the structure in detail, to date. Reported antidiabetic medicinal plants with other properties such as antioxidant and antihyperlipidemic activities deliver new entities for the development of antidiabetic agents with multiple therapeutic targets. This is a comprehensive review on potential antidiabetic activities of the Sri Lankan medicinal plants that have been widely used in the traditional healthcare system. The information presented here would fill the gap between the use of them by traditional healers in the traditional medicine healthcare system in Sri Lanka and their potency for development of new drug entities in future.

“…The chemical composition and morphology of the Sri Lankan Piper species were investigated for utilizing their valuable traits for crop improvement. Piper nigrum, P. betle, P. longum, P. chuvya, P. siriboa L., P. sylvestre, P. zeylanicum, and P. walkeri were examined in morphological and phytochemical studies (Jayarathna et al 2016b) using the specimens collected from natural habitats and cultivation. Thirteen morphological and anatomical characters were subjected to cluster analysis to infer species relationships.…”

“…Thirteen morphological and anatomical characters were subjected to cluster analysis to infer species relationships. According to the phenogram in Jayarathna et al (2016b), the taxa were divided into two main clusters: P. longum, P. zeylanicum, P. sylvestre, P. nigrum, and P. walkeri formed one cluster, whereas P. chuvya, P. betle, and P. siriboa formed a second cluster. This study has played an important role in the crop improvement of P. betle.…”

Highlights• Piper L. (Piperaceae) is one of the most diverse genera among the basal clades of angiosperms.• Available chromosome counts indicate that most wild species are diploids and cultivated species are tetraploids.• Next generation based restriction-site-associated DNA sequencing (RADseq) is a promising genomic tool that could be used to investigate species delimitation and genetic variation within the economically important Piper nigrum (black pepper).• Three-dimensional (3D) floral morphology imaging using computed tomography will aid in the taxonomic revision and understanding pollination biology of this genus.
