Estimation of genetic diversity among Berberis spp. From Karakoram Mountain Ranges using morpho-pathological and floral characters

The present research describes genetic diversity analyses of medicinally important Berberis species (spp.) from great mountainous altitude i.e. Karakoram Mountain Ranges. High range (0-100%) of Genetic Distance estimates using 31 morphological, pathological and floral characters indicated possibilities of improving the material using genetic selection in Berberis spp. Eleven Berberis accessions were classified in 2 main […]

Evaluation of plant diversity indices and the biomass of Pistacia atlantica under drought stress in grazing and enclosed area (case study: Tag-e Ahmad Shahi, Nehbandan, Iran)

Preparing floristic composition is very important to determine vegetation potential in an area to achieve the best pasture management. In order to plant identification in grazing and enclosed areas (each 4 hectares) 40 plots were established (10*10 m) in Tag-e Ahmad Shahi, Nehbandan. This area has involved in a long period of drought and grazing […]

Effects of planting-hole size, composting animal manure and sack on survival and growth of Eucaliptus camaldulensis, Ziziphus spina- christi and Pistasia atlantica planted in Mehran Plain, Iran

This study tested three methods thought to maintain soil moisture availability and thereby improve the performance of three species (Eucaliptus camaldulensis, Ziziphus spina-christi and Pistasia atlantica) when planted in permanent landscape of Mehran plain: increased planting-hole size, composting animal manure and sack addition. Seedlings of the three species were grown in two planting-hole sizes (30*30*30 […]
