Fast-growing trees such as Salix viminalis L. and Populus tremula L. are well suited to phytoremediate heavy metal contaminated soils. However, information on tree performance, particularly leaf function, under conditions of heavy metal contamination is scarce. We used yearly coppiced saplings of S. viminalis and P. tremula growing in model ecosytems to test four hypotheses: (1) heavy metal con...
The chemical composition and the antibacterial activity of the essential oils obtained by hydrodistillation from the leaves of Callistemon citrinus and Callistemon viminalis were analyzed by GC and GC/MS. Twenty-four and twelve components were identified for C. citrinus and C. viminalis, representing 92.0% and 98.3% of the total oils. The major components of C. citrinus and C. viminalis were 1,...
OBJECTIVE Eucalyptus (Fam. Myrtaceae) is a medicinal plant and various Eucalyptus species possess potent pharmacological actions against diabetes, hepatotoxicity, and inflammation. This study aims to investigate essential oil composition from leaves and flowers of E. microtheca and E. viminalis leaves growing in the Southeast of Iran. MATERIALS AND METHODS The aerial parts of these plants wer...
eucalyptus camaldulensis dehnh and callistemon viminalis (gaertn) essential oils were tested against adults (1-3 day old) of tribolium confusum jacquelin du val. in 280 ml glass vials either with or devoid of wheat grains. the oils were also examined for fumigant toxicity against, 5 and 20-day-old larvae. the essential oils were obtained through hydrodistillation, applying a modified clevenger ...
Aims of the study: To describe radial patterns wood density, and to identify their main sources variation, potential tradeoffs with mean tree growth, in two Eucalyptus species. Area Mesopotamian (Corrientes Entre Ríos provinces) Pampean region (Buenos Aires province) Argentina. Materials methods: grandis viminalis, growing genetic trials installed sites per species were studied. X-ray microdens...
استفاده از گونههای سریع الرشد نظیر اکالیپتوسها جهت جنگلکاری در اراضی تخریب یافته جنگلی شمال کشور، نیازمند آزمایشهای سازگاری میباشد تا در نتیجه آن مناسبترین گونهها انتخاب شوند. با این هدف، طرح تحقیقاتی "کشت گروهی مهمترین و سریعالرشدترین درختان صنعتی جهان" در سال 1362 در چمستان به مورد اجراء گذاشته شد. در این طرح تعداد زیادی از گونههای پهنبرگ و سوزنیبرگ در قطعات مجزا کاشته شدند که از جمله...
The plants follow various strategies for adapting and mitigating climatic environmental stresses. This offers an opportunity to comprehend adaptation mitigation mechanisms under changing climate environment emerging from vehicular emissions. We deployed approach, i.e., physiological (Phy) biophysical (Bioph) functional traits (FTs) based approach understand plant response assessing potential of...
اکالیپتوس (Eucalyptus sp.) ازجمله مهمترین درختان عظیم و تند رشد اقیانوسیه است که بیشتر از نیم قرن پیش به ایران وارد شده است و در مناطق جنوب کشور که محیط مناسبی برای کشت آن بوده است، کاشته شده و اکنون درختان کهنسال آن در فارس و برخی از استانهای دیگر مانند لرستان (منطقه ملاوی) دیده میشود. این پژوهش با هدف بررسی سازگاری و عملکرد پروونانسهای گونههای صنعتی اکالیپتوس در استان لرستان انجام شد. ...
The tannery industry is a major source of anthropogenic chromium (Cr) contamination due to the large amounts of solid waste produced and its problematic management. The unique composition of tannery waste, usually high concentrations of Cr and other metals as well as organic matter and nutrients, makes it a great risk for soil and water environment but also a possible effective fertilizer for n...
Dioecy distributed in 157 flowering plant families and 959 flowering plant genera. Morphological and physiological differences between male and female plants have been studied extensively, but studies of sex-specific genetic diversity are relatively scarce in dioecious plants. In this study, 20 SSR loci were employed to examine the genetic variance of male subpopulations and female subpopulatio...
