Most of the research on Phragmites australis is restricted to sites on the European continent even though P. australis occurs abundantly in many regions in the Asian and other continents under different climatic and habitat conditions. The populations used in this study were collected from different parts of Iran. All these populations were grown in the same conditions in experimental field, lo...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

A bamboo coral collected during a deep-sea expedition to the Bahamas in 2009 proved to have a unique combination of features for a member of the bamboo coral subfamily Keratoisidinae: the structure and shape of the polyps, the sclerites consisting entirely of rods, some of which extend the length of the polyp, the delicateness of the branches with solid internodes, and the deep funnel construct...

The iteration of the Lindenmayer system (L-system) has been used to animate the plant growth, however the development of the plant model at each time step is not smooth and continuous. This paper proposes an animating plant growth in L-system by a time embedded component and growth function for the length, size and position of each component of the plant shoot and root, such as, plant internode...

recently, application of sa has increased to improve plants resistance to stresses such as drought. hence, to investigate sa effects on morphophysiological characteristics of fennel(foeniculum vulgare mill.) under drought stress, a split plot experiment based on latin square design with three replications was carried out at research farm of shahid bahonar university of kerman in 2012. three lev...

Dianthus berkayii belongs to sect. Fimbriati was described and illustrated as a new species from Erzincan Province in Eastern Anatolia, Turkey. In the current study morphological, palynological, molecular characters were compared discussed with its closely related species. The is similar D. crinitus fimbriate corolla, linear, acuminate, ± rigid leaves. Also vanensis rigid, curved divaricate But...

Comparison of individual gene trees in several recent phylogenomic studies from diverse lineages has revealed a surprising amount of topological conflict or incongruence, but we still know relatively little about its distribution across the tree of life. To further our understanding of incongruence, the factors that contribute to it and how it can be ameliorated, we examined its distribution in...

St. Augustinegrass is a widely used turf and pasture grass in the southern US. Raleigh is a cultivar known for superior cold tolerance than other St. Augustinegrass cultivars. However, its coarse-leaf texture and long internodes are undesirable when planted in home lawns. Mutagenesis by gamma ray irradiation was employed to treat node cuttings and calli for inducing semi-dwarf growth phenotype....
