in the present study, the effect of two species of amf, glomus mosseae and glomus intraradices, alone and in combination, was evaluated on the growth criteria, chlorophyll content, and root rot disease caused by fusarium solani f. sp. pisi, on chickpea (cicer arietinum l.) under greenhouse conditions. chickpea seeds were sown into pots containing 100 g of amf inoculum (more than 1,000 propagule...
Plant growth regulators, especially those applied directly to the root system, are thought to significantly reduce growth of the root systems. Various perennials were treated with uniconazole (Concise, Fine Americas, Inc.) to evaluate effects on plant height as well as shoot and root dry weights. Plant height of Lobelia cardinalis was not affected by a 1 ppm uniconazole liner dip, but shoot dry...
Root traits influence the amount of water and nutrient absorption, and are important for maintaining crop yield under drought conditions. The objectives of this research were to characterize variability of root traits among spring wheat genotypes and determine whether root traits are related to shoot traits (plant height, tiller number per plant, shoot dry weight, and coleoptile length), region...
fertilization on shoot and fine root growth of Pinus ponderosa Dougl. ex P. Laws. and C. Laws. grown in native soil in open-top field-exposure chambers at Placerville, CA, over a 2-year period. The experimental design was a replicated 3 × 3 factorial with the center treatment missing; plants were exposed to ambient (~365 μmol mol) air or ambient air plus either 175 or 350 μmol mol CO2 in combin...
abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...
the effect of rhizobium leguminosarum bv. phaseoli on uptake and tolerance to arsenic in common bean
abstract arsenic (as) contamination of soils is a global problem. legumes are often used in remediation of contaminated sites because of their capacity to fix nitrogen. in the present study, the effects of inoculation of bean (by rhizobium leguminosarum bv. phaseoli) on plant uptake and tolerance to arsenic were investigated. an experiment with a factorial arrangement, two levels of inoculation...
shoot tips from actively growing, greenhouse maintained plants of kalanchoe blossfeldiana were cultured in vitro for shoot proliferation and root initiation on murashige and skoog (ms) basal medium supplemented with naa and ba, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1. results showed that the maximum plantlets height (7.012 cm), node number (4.516), root number (8.860) and roo...
In order to study the effect of chitosan on growth and some biochemical characteristics of chickpea under salinity stress condition a greenhouse experiment was conducted in Vali-e-Asr University of Rafsanjan in 1392, as factorial arrangement in completely randomized design with three replications. Experimental factors included salinity (0, 4, 6 and 8 dS/m) and level of chitosan (0, 0.1, 0.2%, a...
Provenance-specific growth responses to experimentally applied drought and air warming were studied in saplings of three European oak species: Quercus robur, Quercus petraea and Quercus pubescens. Four provenances of each species were grown in large open-top chambers and subjected to four climates: control, periodic drought, air warming or their combination in 3 subsequent years. Overall growth...
the effect of different ratio of vermicompost (0, 10, 20, 30, 40 & 50 %) in two type of substrate (coco peat and coco peat-perlite (50:50 v:v)) on growth characteristics of gooseberry (physalis peruviana l.) seedling was investigated in research greenhouse of university of tehran, in 2013. a factorial experiment based on completely randomized design with four replications was carried out. crite...
