DSD samples took a longer time (150–180 min) to dry and simultaneously reached higher equilibrium moisture content at the end of rehydration than HAD samples. DSD samples have higher rehydration ability, dry matter holding capacity, and water absorption capacity than HAD samples. Among several empirical models, the Weibull model is the best fit with higher R2 (0.9977), lower root mean square (0.0029), and chi-square error (0.0031) for describing the rehydration kinetics. Rehydrated HAD samples showed better color characteristics than DSD in terms of overall color change, chroma, and hue angle values. Whereas the hardness and chewiness of rehydrated DSD samples were better than HAD samples because of higher dry matter holding capacity in DSD. Apart from color retention, the DSD samples showed better rehydration capacity and a good texture upon rehydration than HAD slices.","PeriodicalId":507088,"journal":{"name":"Trends in Horticulture","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139263747","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 this work, we conducted a comparative physiological response study through some germination parameters between four cereals (Triticum durum, Triticum aestivum, Hordeum vulgare, and Zea mays) grown on a nutrient solution for 10 days and treated with three increasing levels of lead acetate (0.15, 0.3, and 0.6 g/L) in order to evaluate the impact of different lead concentrations on the germination capacity of these species. The results showed that lead has an abiotic stress effect on the four varieties examined at 0.3 g/L and 0.6 g/L. We recorded a significant to very highly significant effect in all the parameters studied. In the underground parts, in particular, a highly significant reduction in precocity of germination was recorded in Triticum durum, Triticum aestivum, Hordeum vulgare, and Zea mays. There was also a highly significant to very highly significant decrease in germination percentage in durum wheat, soft wheat, and maize. Under the most severe stress conditions (0.6 g/L), the barley variety showed stress tolerance with a germination rate of 92%. According to the findings of this study, the varieties examined can be grouped into two categories: variants that are susceptible to metal stress (Triticum durum, Triticum aestivum, and Zea mays) and varieties that are tolerant to lead exposure (Hordeum vulgare).","PeriodicalId":507088,"journal":{"name":"Trends in Horticulture","volume":"115 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262954","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}
{"title":"Targeting H3N2 influenza virus RNA dependent RNA polymerase dependent inhibitory activity by principal components from latex of Calotropis gigantean","authors":"Arun Dev Sharma, I. Kaur, Amrita Chauhan","doi":"10.24294/th.v6i2.2940","DOIUrl":"https://doi.org/10.24294/th.v6i2.2940","url":null,"abstract":"The H3N2 influenza virus is spiking dramatically, which is a major concern worldwide and in India. The multifunctional hetero-trimer influenza virus RNA-dependent RNA polymerase (RdRP) is involved in the generation of viral mRNA and is crucial for viral infectivity, which is directly related to the virus’s ability to survive. The goal of the current work was to use molecular docking to determine how the RdRP protein might be affected by powerful bioactive chemicals found in Calotropis gigantia latex. By applying CB-dock 2 analysis and 2D interactions, an in-silico docking study was conducted using a GC-FID (gas chromatography with flame-ionization detection) based composition profile. Tocospiro A (15%), Amyrin (7%), and Gombasterol A were found by GC-FID to be the main phytocompounds in the latex of Calotropis gigantia. The docking result showed that ligands were effectively bound to RdRP. According to interaction studies, RdRP/ligand complexes create hydrogen bonds, van der Waals forces, pi-alkyl bonds, alkyl bonds, and pi-Sigma bonds. Therefore, it was suggested that Calotropis gigantia latex may represent a possible herbal remedy to attenuate H3N2 infections based on the above findings of the fragrance profile and docking.","PeriodicalId":507088,"journal":{"name":"Trends in Horticulture","volume":"130 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139264698","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}
