A new, simplified and non-destructive estimate of leaf area, leaf fresh and dry weight of greenhouse cucumber Cucumis sativus (Cucurbitaceae) by linear measurements

The estimation of leaf area and leaf fresh and dry weight are used in agronomy to follow the development of crops, and to predict light interception and productivity. In small plant populations using non-destructive methods of leaf area measurements could be useful. In this study because of equipment limitations, the transparent paper and simple ruler […]

Leaf area index and light distribution in olive tree canopies (Olea europaea L.)

The leaf area index (LAI) and the spatial leaf arrangements are the main factors which influenced the radiant energy distribution within the tree. The leaf area index has been shown to be an important factor of the olive productivity. Although, the photosynthetically active radiation intercepted by leaves (PAR) is the main environmental factor that determined […]

Respiration estimation of a plant community through primary values (leaf area and phytomass)

Quantitative analysis of growth represents the first step in the analysis of primary production, being the link between the mere registration of plant productivity and the study of this by physiological methods. In classical growth analysis, most papers on this subject and applications do not provide evidence for the estimation of cellular respiration. This last […]

Heavy metals content in fadama soils, root, leaf and seed of african locust bean tree (Parkia biglobosa) along the river Dilimi in jos north local government area of Plateau state, Nigeria

The aim of the study is to assess the levels of some heavy metal contamination of fadama soils, root, leaf and seed of African Locust Bean (Parkia biglobosa) due to irrigation with sewage fed river water. Samples of water, soils, Parkia biglobosa’ sroot, leaf and seeds were analysed for four heavy metals; Pb, Cd, Mn […]

Leaf mass per area and nitrogen content in cork oak (Quercus suber L.) under a range of climatic stress (drought and temperature stress)

The determination of the diversity of Cork oak tree (Quercus suber L. ) could be a key factor in understanding the response to climate change. This experiment was carried out on 16 stands of Cork oak. Two areas were identified: The Kroumirie and Relicts areas . We try to understand through this study how these […]

Leaf epidermal analysis of some plants in the Ishiagu lead–zinc mining area of South Eastern Nigeria

The study examined the leaf epidermis of some plants growing in a lead-zinc mining area of Ishiagu, Nigeria with the aim of evaluating possible impacts of heavy metal stress on leaf structure. Seven dominant plant species, Adiantum caudatum, Alchornea cordifolia, Centrosema pubescens, Clotalaria retusa, Millettia aboensis, Urena lobata and Vitex doniana were selected for the […]

Floristic composition, life form and leaf size spectra of the coal mine area vegetation of darra adam khel, khyber pakhtonkhwa, Pakistan

An Inventory of plant species of Coal Mine area of Darra Adam Khel was prepared on the basis of field trips conducted in different parts of the year 2009, particularly in winter, summer and monsoon. The flora consisted of 54 plant species belonging to 30 families. The dominant families were Asteraceae, Lamiaceae and Solanaceae with […]

Assessment of the crude ethanol leaf extracts of Momordica charantia Linn., Moringa oleifera Lam., Tabernaemontana pandacaqui Poir. and Mollugo oppositifolia Linn. for its wound healing activity in castrated piglets

Botanicals possess healing and medicinal properties which could be an alternative to synthetic therapeutic drugs. The study evaluated the healing activity of selected botanicals on castration wounds of piglets. Crude ethanol leaf extracts of selected botanicals were subjected to wound healing activity assessment. Wound surface area, photography of wounds, epithelialization and scar appearance were assessed.  […]

Biogenic Synthesis of Magnetite Nanoparticles from Leaf and Latex Extract of Calotropis gigantea for Sunlight Mediated Photocatalytic Degradation of MB Dye

Iron oxide nanoparticles, specifically magnetite (-NPs), have become widely used and a significant area of research due to their superparamagnetism and distinctive properties. As a result, scientists are diligently looking into new uses for these nanoparticles. The choice and use of synthesis techniques are important variables that can affect the size and characteristics of the […]

Composition and diversity of mangrove vascular flora in coastal area of Pangasihan, Gingoog City, Philippines

Mangrove ecosystem is a unique community of trees with substantial ecologic and economic significance. A non-destructive belt transect was utilized in determining the mangrove species composition and diversity. Different parts of the mangrove trees were photographed for proper identification, taxonomic classification and morphological description. These studies revealed that the mangrove vascular flora of Pangasihan mangrove […]
