The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas (Pisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems. Plants of the F 1, F 2 , backcross and parental generations were evaluated in pots filled with soil: sand mixture, in a completely randomized de...

in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

in order to study the effect of different water potential on anethum graveolens l. an experiment was conducted. this study was carried out based on completely randomized design with three replications. in this experiment, morpho-physiological characteristics were assessed under hydroponic. stress was established with peg 6000, and drought potentials were: 0 (control), -1.5, -2, -2.5 and -3 bar....

shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...

in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...
