Pistacia vera L. is a decidious tree. To investigate the influence of soaking seeds in polyamines (PAs) spermine (Spm), spermidine (Spd) and putrescine (Put) on seed germination and enhancing lateral root development of ‘Ghazvini’ pistachio seedling rootstock, the experiment were carried out in petri dishes and plastic bags. Seeds were soaked in PAs( Spd, Spm, and Put) at three concentrations( ...

Tomato plants were inoculated with Meloidogyne incognita at initial populations (Pi) of 0, 1, 10, 50, 100, and 200 (x 1,000) eggs per plant and maintained in a growth chamber for 40 days. Total fresh biomass (roots + shoots) at harvest was unchanged by nematode inoculation with Pi of 1 x 10 eggs or less. Reductions in fresh shoot weight with increasing Pi coincided with increases in root weight...

this experiment was conducted to determine allopathic effects of cyperus rotundus extracts on the tomato germination. it was a completely randomized design (crd) with four replications, carried out in the laboratory of the agricultural college of university jiroft during 2011. the various test treatments were extracts of cyperus rotundus taken from aerial organs, root, and combinations of both ...

Objective: In order to study the effect of different concentrations of IBA hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in Jiroft, Iran. Methods: a split-plot experiment was conducted on the basis of a Randomized Complete Block Design in which hardwood cuttings of one-year-old olive plants cv. Manzanilla with the diameter of 0.7-1 cm were used. The main...

the aim of this study was to evaluate the effect of different potassium (k) and nitrogen (n) concentrations in nutrient solution and their interaction on growth and quality of tomato transplants. a full factorial experimental design was carried out with three potassium concentrations (1.5, 3 and 6 meql-1) and three nitrogen concentrations (1.5, 3 and 6 meql-1) for 27 days after seed germination...

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during July to December 2006 to study the root growth of four Transplant Aman rice varieties as influenced by NPKS fertilization. The experiment was laid out in a split-plot design with three replications. The experiment consisted of four varieties viz. BRRI dhan30, BRRI dhan31, BRRI ...

Salinity and heavy metals affect the growth and development of higher plants and also their productivity. In the present study, Cauliflower (Brassica oleracea var botrytis) seeds were allowed to germinate and grow in the absence (control) and presence of different concentrations (50, 100, 250, 500, 750 and 1000 μM) of NaCl, CdCl2, HgCl2 and ZnCl2. Seed germination and growth parameters of seedl...

Background & Aim: This experiment investigated the effect of foliar application of methanol and ethanol on the biomass yield of medicinal plant Echinacea purpurea. Purple coneflower is an herbaceous perennial in the Asteraceae family that is used in therapy of respiratory tract infection and bacterial otitis. Experimental: This experiment was conducted in randomized complete ...
