good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. in this experiment this relation has been checked out. the morphological traits were included plant height, peduncle length and spike density. we used 28 spring wheat genotypes and 2 durum genotypes. there was sig...

root depth and distribution have an important role in drought resistance and optimization of moisture content of soil. this research was carried out in order to consider of root response of triticale genotypes to water stress and recognition of root trait that can effective in resistance of water stress. this experiment was in a factorial experiment based on completely random design on the year...

Tomato (Lycpoersicum esculemtum) belongs to the Solanaceae potato family and is an important crop plant. It is relatively resistant to salinity, but in the saline environment growth and production of the plant significantly reduces. On the other hand, the presence of mycorrhiza fungus can improve the adverse effects of salinity. A factorial experiment in a completely randomized design with thre...

to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...

to investigate the effect of spraying with different concentrations of vermiwash solution on the morphological traits, percentage and yield of essential oil of lemon balm (melissa officinalis l.), this experiment was conducted as randomized complete block design (rcbd) with four replications in experimental field of agricultural faculty of ferdowsi university of mashhad (fum). the treatments we...

a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...

to study the effects of plant density and nitrogen rates on the ability of canola (regent  cobra; an inbred variety) to compete with weeds, an experiment was conducted as a factorial complete block design with four replications. the treatments included four levels of plant density at 150, 190, 230, and 270 plants m-2, and four levels of nitrogen (n) fertil-izer at 0, 46, 92, and 138 kg ha–1. r...

in order to investigate the effect of root pruning in morphological and physiological characteristics of juniperus excelsa seedlings an experiment was carried out on transplanted one year-old seedlings. treatments included root pruning intensities (1-slight pruning (2-moderate pruning and 3- control (no root pruning)) .experiment design was completely randomized design. each treatment included ...
