Pistacia vera cv Badami-e-Riz is the most important and popular rootstock in Iran, which tolerate salinity soil and phytophthora fungi but its root is less affected. In addition this rootstock is susceptible to excessive B and water deficient. This rootstock has a taproot rooting system without any lateral root. So this study was conducted to evaluate the effects of various concentrations and a...
In order to evaluation of morphological selection criteria for salt tolerance screening in wheat (T. aestivum L.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. Salinity treatments involved 4 levels: S=1.3dSm-1 (control), 5, 10, 15 dSm-1 from calcium chloride and sodium chloride with 10:1 (Na: Ca ratio) and another facto...
light is one of the important environmental factors seriously affecting plant growth. given the availability of roots in aeroponic system, the influence of various light rays emitted towards the root zone of anthurium was studied. foliar spray of calcium nitrate in concentration of 10 mm was tried because of the high importance of calcium element in enhancement of vase life and strength of cut ...
To investigate the effect of cadmium (Cd) on some physiological parameters of safflower genotypes a 3-replicate factorial randomized complete blocks experiment was conducted under hydroponics culture in greenhouse facilities of the Isfahan University of Technology in 2012. Four levels of Cd (control (0), 1.5, 3.0 and 4.5 mg/L) were tested on six safflower genotypes (Arak2811, Kouseh, Nebraska...
ficus benjamina l. is indoor plant in temperate areas that is a tree species belongs to moraceae family. propagation of this plant is down by vegetative method. this study was conducted to evaluate the effect of iba concentration and time of taking cutting on propagation of ficus benjamina via stenting technique in gorgan university of agricultural sciences and natural resources, in 2012. treat...
The effects of different concentrations of Zinc oxide nano particles (ZnONP; 0, 10, 25, 50, 75 and 100 mg L-1) and Humic acid (HA; 0, 50, 100, 500 and 1000 mg L-1) on root length and number, leaf length and number, bulb diameter, and chlorophyll, total phenol, anthocyanin and flavonoid contents were examined under in vitro conditions. Total phenol, flavonoid and anthocyanin contents were signif...
Ficus benjaminais a very popular and resistant indoor plant in temperate areas. Cutting is the easiest propagation method of this plant and it requires special treatments such as auxin and appropriate rooting medium. In order to test the suitable auxin (IBA) concentration and rooting media, a factorial experiment carried out based on randomized complete block design with three replications. Exp...
Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...
