A study was conducted to observe the effects of two hormones viz., Indole Butyric Acid (IBA) and Seradix-A on growth and rooting percentage of Rosa bourboniana cuttings. Experiment was laid out according to Randomized Complete Block Design and there were four treatments, replicated four times. In the second experiment two Rosa species i.e. Rosa bourboniana and Gruss an teplitz were selected as ...

Potted bougainvillea `Purple Flower' and `Taipei Red' in four different stages of bract development were sprayed with STS (0.1, 0.5 mM) or NAA (25, 50 ppm) and were moved to lowlight indoor conditions after treatment. The experiment was conducted twice, and the results showed that 0.5 mM STS and NAA (25, 50 ppm) could signi®cantly prolong the longevity of bracts at certain stages in both cultiv...

in order to evaluate the effects of drought stress and planting method on some physiological and biochemical characteristics of two chickpea cultivars (cicer arietinum l.) an experiment was conducted at the research station of college of agriculture, shiraz university using a split factorial based on randomized complete block design in four replications. the main factor was stopping irrigation ...

Understanding how elevated CO2 affects dynamics of nodal leaf growth and N assimilation is crucial for the construction of high-yielding canopy via breeding and N management to cope with the future climate change. Two soybean cultivars were grown in two Mollisols differing in soil organic carbon (SOC), and exposed to ambient CO2 (380 ppm) or elevated CO2 (580 ppm) throughout the growth stages. ...

three different concentrations (10, 20 and 30 ppm) of the dry propolis and pollen extracts were applied in double distilled water. biochemical and hematological parameters in blood of rainbow trout (oncorhynchus mykiss) treated to various propolis and pollen concentrations (10, 20 and 30 ppm) for 96 h were determined.  fish treated to 20 and 30 ppm of propolis extract presented significant incr...

Nitrogen dioxide (NO2), the oxidation product of nitric oxide (NO), is a reactive free radical forming gas, the inhalation of which has been reported to induce severe damage to distal airways. In order to quantify dose and time course of parenchymal and vascular damage, rats were exposed to 5, 10 and 20 ppm NO2 for 3 and 25 days, followed by quantitative histology and morphometry of the lung. H...

in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...

Rice blast, caused by Magnaporthe grisea Cav., frequently limits rough rice yields and cultivar options in Arkansas rice production areas. Rice growers and researchers have long observed that susceptible rice plants are more blast resistant when growing in moisture saturated or flooded soil. In fact, Arkansas growers utilized flood-induced field resistance as their primary blast control measure...
