The group variability of morphological features the leaves Betula pendula Roth was studied in gradients adverse weather conditions and technogenic soil transformation. studies were carried out on territory Tagil zone Middle Urals 2016–2019. It has been revealed that most leaf traits have an average level variation, while a high one is characteristic shape index, low blade index angles between m...

The article describes the contribution of famous Ukrainian scientist Vasyl Matviyovych Chernyaev to science botany and development herbarium. Biographical data are given.
 Among funds Herbarium (UM) students Uman School Agriculture Horticulture (the successor is National University Horticulture) a valuable historical collection exicates Florae Rossicae (1897–1907). It was established that ...

The Canadian Entomologist 32: 965 981 (2000) Leaf and bark volatiles from non-host birches, Betula pendula Roth. and Betula pubescens Ehrh. (Betulaceae), and aspen, Populus tremula L. (Salicaceae), were tested on spring-dispersing Tomicus piniperda (L.) and Tomicus minor (Hart.) by gas chromatographic electroantennographic detection (GC-EAD) and by attractantbaited traps in southern Sweden. GC-...

A modified version of a method that uses positive air pressures to determine the complete cavitation response of a single axis is presented. Application of the method to Betula occidentalis Hook, gave a cavitation response indistinguishable from that obtained by dehydration, thus verifying the technique and providing additional evidence that cavitation under tension occurs by air entry through ...

This study represents a systematic attempt to explore the knowledge of the native people about plants, which they use to cure diseases. And it is an attempt towards conserving the local knowledge of people to plants. This paper presents a list and uses of some medicinal plants distributed in the high altitude district Kishtwar in Jammu and Kashmir. The list was prepared during an ethno-botanica...

The roots of nearly all land plants form mycorrhizal symbioses with specialized soil fungi. The mycorrhizal fungi serve as extensions of plant roots, taking up nutrients and water and transferring them to the roots. In return, the mycorrhizal fungi receive their primary energy source in the form of simple sugars from plant photosynthates translocated to the roots. Sequoiadendron giganteum forms...

A parsimony analysis was conducted on 319 rbcL sequences, comprising 242 from 194 genera of Leguminosae and 77 from other families. Results support earlier conclusions from rbcL and other molecular data that a monophyletic Leguminosae is part of a Fabales that includes Polygalaceae, Surianaceae, and the anomalous rosid genus Quillaja. Within legumes, results of previous analyses were also suppo...
