Morphotypes of Tilia spp. fruits in Hyrcanian forests
Variations in fruits morphology of Tilia spp. were studied along longitudinal and altitudinal range. Ten populations of Tilia spp.from Golestan, Mazandaran and Gilan Provinces (N. Iran) were selected. After biometrical measurements and Scanning Electron Microscopic (SEM), Cluster Analysis divided the population into seven groups. Discriminat Analysis showed that among all traits studied, size o...
متن کاملChlorophyll Catabolites in Senescent Leaves of the Lime Tree (Tilia cordata)
In cold extracts of senescent leaves of the Lime tree (Tilia cordata), two colorless nonfluorescent chlorophyll catabolites (NCCs) were identified, named Tc-NCC-1 and Tc-NCC-2, as well as a polar yellow chlorophyll catabolite (YCC), named Tc-YCC. The constitution of the two NCCs was determined by spectroscopic means. In addition, a tentative structure was derived for Tc-YCC. The three chlorophy...
متن کاملEriophyes species (Acari: Eriophyoidea) inhabiting lime trees (Tilia spp.: Tiliaceae)--supplementary description and morphological variability related to host plants and female forms.
Three poorly known species of the subfamily Eriophyinae living on Tilia spp. (Tiliaceae) are illustrated and supplementary descriptions are provided. Two of them, Eriophyes exilis (Nalepa 1892) and Eriophyes nervalis (Nalepa 1918), were recorded both in vein angle galls on leaves of Tilia platyphyllos Scop. and in erinea on leaves of Tilia tomentosa Moench, Tilia americana L. 'Moltkei', Tilia a...
متن کاملتنوع ریختی برگ نمدار (Tilia spp.) در جنگل‌های هیرکانی
به منظور بررسی حضور گونه‌های متفاوت جنس نمدار در جنگل‌های هیرکانی، بعد از نمونه‌برداری برگ در سراسر محدوه پراکنش آن در شمال ایران، اقدام به بیومتری صفات مورفولوژیک و مطالعه نوع کرک‌های سطح پشت و روی برگ با استفاده از میکروسکوپ الکترونی گردید. نتایج حاصل از بررسی ریخت‌شناسی، وجود هفت گروه با صفات ریختی متمایز را تأیید می‌نماید. تحلیل ممیزی، صفات حضور کرک در پشت و روی برگ، شکل حاشیه برگ و حضور کر...
متن کاملPotential of Near Infrared Spectroscopy for Authenticity Testing of Unifloral Honey
321 honey samples from Switzerland were collected. The botanical authenticity of 176 honey samples was confirmed by the determination of electrical conductivity, sugar composition, pH-value, free acidity, and microscopical pollen analysis [2], as well as the sensory evaluation by three experts. The honey samples were assigned to one of the following groups: floral honeys from acacia (Robinia sp...
