In order to estimate the loss of rice caused by white tip nematode, (Aphelenchoides besseyi), to Alikazemi cv., two series of experiments were conducted in greenhouse and microplot conditions at Rice Research Institute, Rasht (Guilan province) during 2005-2006. The microplots sizes were 0.5×2 meter. Rice seedlings were inoculated by plastic tube method with 0, 100, 300, 500, 700 and 900 nematod...
Smirnovia iranica (Sabeti) synonym: Smirnovia turkestana (Bunge) is a deciduous perennial bushy species of the Fabaceae (Papilionaceae) family. The species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. They have an important role in natural vegetation of desert and sand dune stabilization. Limited growing areas, grazing due to good pa...
Blueberry replant disease (BRD) is an emerging threat to continued blueberry (Vaccinium spp.) production in Georgia and North Carolina. Since high populations of ring nematode Mesocriconema ornatum were found to be associated with commercially grown blueberries in Georgia, we hypothesized that M. ornatum may be responsible for predisposing blueberry to BRD. We therefore tested the pathogenicity...
a comparative study was conducted to find a reliable and simple method for evaluation of resistance of sugar beet genotypes to rhizoctonia root and crown rot. for this, 12 sugar beet genotypes were used in greenhouse, field and in vitro experiments. the field experiment was performed in micro plots (1×1×2 meter) using randomized complete block design with 4 replications. prior to planting, the ...

Recently, the use of biological compounds to ameliorate the effects of environmental stresses on agricultural products has been considered globally. In order to investigate the ameliorating effect of some biological compounds on fluorescence indices, photosynthetic pigments and yield of greenhouse tomatoes under deficit irrigation conditions, the split plot experiment was conducted as a randomi...
Application of salicylic acid (SA) as a phytohormone has been increased due to resistance to stresses such as salt stress. To evaluate the effects of SA on growth and ornamental characteristics of Persian petunia under salt stress, a factorial experiment, based on completely randomized design, was conducted with 3 levels of SA (0, 1 and 2 mM) and 3 levels of NaCl (0, 150 and 300 mM) with 4 rep...
The CLAW hypothesis argues that a negative feedback mechanism involving phytoplankton-derived dimethylsulfoniopropionate (DMSP) could mitigate increasing sea surface temperatures that result from global warming. DMSP is converted to the climatically active dimethylsulfide (DMS), which is transferred to the atmosphere and photochemically oxidized to sulfate aerosols, leading to increases in plan...
rosy apple aphid, dysaphis plantaginea (passerini), with worldwide distribution is an important pest of apple orchards. host plant resistance is an essential component of integrated management of this insect pest. we investigated the resistance of seven apple cultivars, malus domestica (borkhausen), namely granny smith, starkrimson, golden smoothee, red delicious, golden delicious, boshghabi, a...
