In a series of experiment, the response of two contrasting potato species, namely, Solanum acaule (tolerant) and Solanum tuberosum cv. Agria (intolerant) to salt (80 mM NaCl) and drought stress (15% polyethylene glycol;PEG) was studied in vitro. Furthermore, the role of acetyl salicylic acid (ASA) (1 and 10 µM) in alleviating oxidative stress was investigated. In Agria cultivar, NaCl and PEG r...
To study the effects of plant densities and planting orientation on the seed and forage yield of sorghum, an experiment was conducted at Hossein- Abad – Shahcal village –90 kilometers south of Bam-in 2002. The experiment was a factorial with randomized complete block deisgn and three replications. The treatments were: orientation with three levels (South-North, East – West, Northeast – Southwes...
In order to investigate the effect of different levels of water stress on Satureja hortensis, a completely randomized design (CRD) with four replications was carried out in the greenhouse of Yazd University in 2014. The water stress treatments including 100, 75, 50 and 25 Percent of field capacity (FC) were applied. The results showed that water deficit stress significantly (p<0.01) decreased p...
To investigate the effect of applying different amounts of municipal solid waste compost (MSWC) and sewage sludge (SS) on yield and concentration of some heavy metals including nickel (Ni), chromium (Cr), cadmium (Cd) and lead (Pb) in organs of green pepper plant, a pot experiment was conducted as a completely randomized design with seven treatments and four replications. Treatments included co...
Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but a...
The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As) uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment. Non-mycorrhizal and zero-P addition controls were included. Plant biomass and concentrations and uptake of As, P, and other nutrients, AM colonization, root leng...
in order to investigate the effects of piriformospora indica and trichoderma tomentosum fungi on basil (ocimum basilicum l.) growth under copper nitrate levels, a pot experiment in factorial arrangement with three replicates was done during 2012. treatments were four levels of copper nitrate (0, 100, 200 and 300 mg kg-1 of soil) and four levels of fungal coexistence (non-inoculation control, in...
in order to evaluate the effect of different levels of salinity and three nitrogen nutrition on biochemical reactions and changes in dry weight of shoot and root on psyllium (plantago ovata f.), a glasshouse experiment in a complete randomized design with three replications in 2009 at university of zabol was conducted. salinity treatments in this experiment were 0, 100 and 200 mm of nacl and ni...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Salicornia europaea is a halophytic annual plant of the Chenopodiaceae family, which is considered as an oil plant in marine irrigation. This experiment was conducted to determine the effect of salinity and to reach the best hormonal treatment for shoot regeneration. After washing and sterilization, seeds of S. europaea were cultured under controlled light and temperature conditions at five sal...
