sainfoin (onobrychis viciifolia scop.) is a perennial forage legume has recognized for its feed value and high stability. this experiment was conducted to investigate the relationship among morphological and agronomic traits using multivariate statistical methods including correlation, regression and factor analysis. twenty one accessions of sainfoin were evaluated in a randomized complete bloc...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

Restoration of wet prairie in the central midwestern United States should include Prairie cordgrass (Spartina pectinata), but historic densities of this once dominant species are not easily achieved. Spartina pectinata was transplanted into a former agricultural field in three planting strategies: 20 small plugs, 4 medium-sized plugs, and a single large plug, with each treatment area totaling 0...

the oriental beech constitute one third of northern forests area and stocking volume in the north ofiran. these stands obseve in pure and mixed. in order to properly management which guaranteesustained yield, it is crucial to collect basic information including stocking (volume and stem number),tree growth, diameter distribution pattern, diameter-height relationship, diameter-volume relationshi...

in order to study of ecological and phenological traits of ferulago angulata asan important medicinal plant, this research was conducted in hezar mountains andbondareh henza in kerman province, iran. random samples of this plant were taken andtheir vegetation habitat conditions and their growth characteristics including height ofcollar leaves, height of flower stem, flower stem number and forag...

Currently, little information is available to estimate individual tree attributes for longleaf pine (Pinus palustris Mill.), an important tree species of the southeastern United States. The majority of available models are local, relying on stem diameter outside bark at breast height (dbh, cm) and not including stand-level parameters. We developed a set of individual tree equations to predict t...

Non-chemical control of plant growth is an important goal for the production of ornamental pot plants. In the present study the effects of simulated vibration on plant height and some physical and mechanical properties of Coleus stem were investigated. The study was conducted as a factorial experiment based on a completely randomized design with three replications. Vibration stresses were perfo...

Due to the econemic and envaironmental limitiation in the use of peat moss as a growth medium of ornamental plants, researchers seek an apporiate alternative in flower and plants industry. Zeolite because of the high capacity of water holding and cations enchange, has an ability in the replacement  of peat moss. At this research, the posibility subtitution of peat moss by zeolite as a growth me...
