The effects of 2 concentrations of kinetin, i.e., 2 and 4 mM together with 2 levels of drought stress, i.e., moderate (35% soil saturation capacity) and severe (20% soil saturation capacity) were investigated on the growth parameters of tomato including fresh and dry leaf weight, leaf number, leaf surface area, fruit number, fruit weight, and enzymatic antioxidants. To this end, first tomato pl...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

The efficacy of amitraz on cattle ticks was assessed by susceptibility tests, spraying and dipping trials. Tests on the susceptibility of three tick species, Rhipicephalus appendiculatus, Amblyomma variegatum and Boophilus decoloratus to amitraz (technical grade-purity 98.6% w/w) showed all 15 tick strains tested to be highly susceptible, with LC50 ranging between 0.001% and 0.03%, and LC99, be...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

In general, drainage can be used to reduce excess water, whether from rainwater, seepage, or irrigation water an area, so that the function of area is not disturbed. This study aims analyze and examine problems exist on Untung Jawa Island, South Seribu Islands District, DKI Jakarta, channels are poorly maintained frequent flooding. The data in this primary secondary data, planning calculation f...

Drought tolerance is an important trait being pursued by the agbiotech industry. Abscisic acid (ABA) is a stress hormone that mediates a multitude of processes in growth and development, water use efficiency (WUE) and gene expression during seed development and in response to environmental stresses. Arabidopsis B3-domain transcription factor Related to ABA-Insensitive3 (ABI3)/Viviparous1 (namel...

powdery mildew disease caused quality and quantity losses of sugar beet production. therefore, five spraying treatments and three sugar beet variety were conducted in split plot design with four reapplications during consecutive two years in kermanshah and mashhad regions. in order to control of disease, tridimorph fungicide was used. spraying treatments were in main plot and variety in the sub...

introduction dehydration is one of the limiting factors of crop production. it results from increasing the amount of water losses from leaf or inadequate water absorption rate or combination of both. zinc used in many enzymes of the plant tissues and have catalytic role in activation of some enzymes. zinc is involved in the synthesis and degradation of proteins and is an essential micronutrien...
