One of the ways to reduce concentrated greenhouse gases in the atmosphere is to enlarge forest areas and encourage forest regeneration after fires. The given paper describes sterilization methods of primary explants. Studies have shown that 0.1% diacid solution supplemented with Tween 20 is the most effective at producing aseptic viable cultures of triploid aspen (Populus tremula L.) in vitro. This method provides the necessary amount of viable sterile cultures for their subsequent micro-multiplication (clonal), sufficient for the further mass production of planting material. Murashige & Skoog (MS) medium supplemented with 6-benzylaminopurine (BAP) had a more intensive formation of adventive buds compared to the medium with kinetin. Higher BAP concentration resulted in more regenerants from one explant with their height shortened. Woody Plant Medium (WPM) with different concentrations of 6-benzylaminopurine and indolyl-acetic acid (IAA) is more effective for working with triploid aspen. Effective reproduction at triploid aspen cultivation was shown at 0.5 mg/l concentration of BAP. The research results can be successfully used in vitro culture introducing of triploid aspen, experiments on micro-reproduction of other tree crops to get high-quality planting material.","PeriodicalId":7048,"journal":{"name":"生态学报","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135763852","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}

Initially, crude extracts of hexane, chloroform, and methanol from A. paniculata leaves were evaluated for their efficacy against Ae. aegypti and Cx. quinquefasciatus mosquitoes, with the methanol extract showing promising activity. Subsequently, a comprehensive methanol extraction of A. paniculata leaves was conducted, followed by fractionation via column chromatography using various eluents, including chloroform, ethyl acetate, methanol, and their combinations. This process yielded 80 fractions, which were consolidated into 10 fractions based on thin-layer chromatography (TLC) profiles. Each fraction was assessed for ovicidal, larvicidal, and pupicidal activity across concentrations of 2.5, 5.0, 7.5, and 10 ppm. Among these fractions, ‘F-4’ exhibited exceptional efficacy against the larvae, pupae, and eggs of both mosquito species. At a concentration of 10 ppm, ‘F-4’ achieved 100% larval mortality, with LC50 values of 7.2 ppm for Ae. aegypti and 5.0 ppm for Cx. quinquefasciatus. Additionally, ‘F-4’ demonstrated substantial pupicidal activity, with LC50 values of 7.6 ppm for Ae. aegypti and 5.7 ppm for Cx. quinquefasciatus. Furthermore, ‘F-4’ exhibited ovicidal activity, with efficacy ranging between 77% and 78%. These results highlight ‘F-4’ from A. paniculata shows promise as an eco-friendly biocontrol agent against Ae. aegypti and Cx. quinquefasciatus mosquitoes, warranting further investigation for sustainable mosquito control.","PeriodicalId":7048,"journal":{"name":"生态学报","volume":"95 2-3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135411870","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}

The objective of this investigation was to improve the stable yield and quality of the essential oil. Traditional breeding relies heavily on the harvesting phase to maintain consistency in the essential oil content. Findings from the AMMI and GGE analyses showed that various kinds exhibit both general and niche environmental adaptability. The mean essential oil yields, as well as geraniol and geranyl acetate, were significantly influenced by both genetic variation and environmental variables. The stability of the traits is also influenced by the correlations between different attributes across the four stages of the eight seasons/environments. Pr2 at full blooming stages 1 and 2 and Pr4 at full blooming stage 1 had stability for the maximum oil yield, geraniol, and geranyl acetate, based on the overall average of the eight seasons/environments in four stages of the crop. Because they have higher G × E, which makes them more sensitive to environmental changes, the AMMI model identified Pr2 at full flowering stages 1 and 2 and Pr4 at full flowering stage 1 as being more stable and better suited to their environments. Of the four varieties studied, Pr2 full flowering stages 1 and 2 and Pr4 full flowering stage 1 were identified as higher essential oil yielders and stable, and they also possessed other desirable characteristics like high herb’ plant height, branches/plant, geraniol content, and geranyl acetate content. Therefore, commercial-scale production should take advantage of these stable cultivars.","PeriodicalId":7048,"journal":{"name":"生态学报","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135706132","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}
