generation neural stem cells from neurosphere–derived bone marrow stem cells using bioactive substance atc. bone marrow cells (bmscs) were isolated from rat. bmscs cultured by dmem/f12 medium supplemented with 10% fetal bovine serum. these cells evaluated by specific markers of bmscs such as bioactive substance atc, b27. then bmscs differentionated in to neurosphere and divided in two groups wh...

tomato  (l.ycopersicon esculentum  mill.) cv. rio grande  seedlings were nutritionally conditioned with solutions complete fertilizer n(60% no3+40% nh4)-p-k (20-20-20) , n(30%no3+70% nh4)-p-k (15-5-30) , the first two week   n(60% no3+40% nh4)-p-k (20-20-20) and later two week  n(30%no3+70% nh4)-p-k (15-5-30)  and vice versa were  applied in  completely randomized experiment with three replicat...

Investigation on structure and dynamics of natural forest ecosystems is an important issue for silvicultural decisions. The aim of this study is to analysis dynamics and structure of a beech stand during 5-year period in the Shast Kalateh forest in the Caspian region, North of Iran. Data were collected from a 16.9ha permanent research plot established in a natural unlogged stand in 2006. All li...

in order to evaluate the effects of planting pattern on morphological, phonological, yield and yield components of sweet and super sweet corn (zea mays l.) varieties under saline conditions, a field experiment was conducted as split plots based on a randomized complete block design with four replications. planting pattern in 3 levels included one row in ridge, two row in ridge and furrow planti...

Biomass is the component of living organism and mostly obtained from plants, animals, insects and the residue of all the mentioned organisms. Biomass is the key source of energy present in the form of organic matter. The study aimed to find out biomass and its variation in each component of Betula utilis D. Don (Birch Tree) with varying diameter at Kalam forest division Swat, Khyber Pakhtunkhwa...

A young potted oak (Quercus robur L.) tree was subjected to drought by interrupting the water supply for 9 days. The tree was placed in a growth chamber in which daily patterns of temperature and radiation were constant. The effects of drought on the water and carbon status of the stem were examined by measuring stem sap flow rate, stem water potential, stem diameter variations, stem CO(2) effl...

Background & Aim: This experiment investigated the effect of foliar application of methanol and ethanol on the biomass yield of medicinal plant Echinacea purpurea. Purple coneflower is an herbaceous perennial in the Asteraceae family that is used in therapy of respiratory tract infection and bacterial otitis. Experimental: This experiment was conducted in randomized complete ...
