Conifers, a component of beauties of parks and landscapes, are infected with diverse pathogens, especially fungi. In this research, samples were collected from conifers displaying symptoms of disease in parks and landscapes of Rasht in Iran and for the isolation and identification of pathogenic fungi, pieces of infected tissues were placed in PDA and at the next stages in WA, PCA and SNA media ...

• Here we explore the possible role of leaf-level gas exchange traits in determining growth rate differences and competitive interactions between evergreen angiosperms and conifers. • We compared relationships among photosynthetic capacity ( A max ), maximum stomatal conductance ( G s ), leaf life span, nitrogen concentration (N) and specific leaf area (SLA), in sun leaves of 23 evergreen angio...

BACKGROUND AND AIMS Conifers dominated wet lowland tropical forests 100 million years ago (MYA). With a few exceptions in the Podocarpaceae and Araucariaceae, conifers are now absent from this biome. This shift to angiosperm dominance also coincided with a large decline in atmospheric CO2 concentration (ca). We compared growth and physiological performance of two lowland tropical angiosperms an...

In the framework of collecting and identifying of wood fungi of Iran, specimen of cup fungus from wood and debris of conifers was collected. The characteristic features of specimen were as follows: Fruit body cup-shaped, gelatinous, up to 1 cm high and to 1.5 cm wide; bright orange. Fertile surface concave. Spores sausage-shaped, smooth, up to 4-5-celled, 15.5-18 × 4-6 µm. Basidia shaped like a...

exploration of natural products with antitumoral effects such as etoposide, tenioposide, camptothecin and paclitaxel from conifers provoked us to do some research on anti-tumoral activity of iranian medicinal plants. ten different species of iranian conifers aerial parts were collected across the country. the relative potency of methanolic extract were investigated on the inhibition of topoisom...
