A pot experiment was designed to investigate the effects of full, above and below ground interactions of wheat with wild oat on leaf characteristics and root to shoot ratio. This experiment was conducted as a factorial based on randomized complete design with four replications. The treatments included four interference levels (above ground, below ground, above and below ground and check wheat a...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
In silver cypress (Cupressus arizonica), rooting of cuttings is not easily possible. To optimize the rooting properties of cuttings of this plant, a factorial experiment was conducted as multi-factor, based on a completely randomized block design with 4 replications and 4 cuttings in each replicate. In this study, four different types of cuttings (consisting of above-terminal, above-basal, belo...

objective: drought stress is most important factor which reduce root and shoot growth in crops. this study was performed in order to evaluate the effects of drought stress and zn fertilizer on root traits of four cultivars of chickpea. methods: experiment was laid out in a split plot-factorial using randomized complete block design with three replications. drought stress treatment stand in main...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Pistacia vera cv Badami-e-riz and P.vera cv Ghazvini are the most important and popular rootstocks in Iran, which tolerate salinity and phytophthora fungi. This study was conducted to evaluate the effects of various concentrations of polyamines and IBA on root regeneration of transplanted bare- rooted ‘Badami-e-riz’ and ‘Ghazvini’ pistachio rootstocks. The mean comparison between IBA and polyam...
in order to study the effect of pyridate, bentazon and imazethapyr herbicides on chickpea growth, nodulation and biological nitrogen fixation, a greenhouse experiment was conducted at ferdowsi university of mashhad in 2010. experimental type was completely randomized design with four replications. treatments included pyridate, bentazon and imazethapyr herbicides application in 1200, 720 and 75 ...
the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...
