in this research the effect of two species of arbuscular mycorrhizal fungi, glomus mosseae and glomus intraradices on root knot nematode, meloidogyne javanica was investigated and in different treatments the effects of this interaction on parameters of plant growth , nematode infection and mycorrhizal development were evaluated.shoot fresh and dry weight significantly increased in mycorrhizal t...
The effects of 4 different levels of nitrogen (0,120,150, and 180 kg nitrogen per hectare) and one level of poultry manure (10 tons per hectare) on the quantitative and qualitative characteristics of an autumn grown cultivar of cucumber [Cucumis sativus, cv.'super dominos] were studied in DarrehShahr, Ilam. The experiment was conducted in a completely randomized block design with 3 replications...

Estimation of genetic variation is very important in breeding programs and existing of high genetic variation lead to increase the response to selection. The objective of this study was to investigate genetic variation for agronomic traits and yield components in 12 alfalfa half-sib families. Thirty five individuals of each half-sib family were grown and analyzed basis of completely randomized ...
In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...
to investigate the effects of deficit irrigation and different levels of nitrogen fertilizer on somequantitative and qualitative properties of melissa, a pot experiment was conducted for one year (2011) inmazandaran province. experiment was carried out as a factorial based on randomized complete blockdesign with three replications. irrigation treatments (25, 52 and 75 percent field capacity, fc...
A soilless cultivation experiment, in a medium containing sand, perlite and peat, based on Hoagland nutrient solution, was designed and carried out to investigate the growth and postharvest response of Zinnia to different concentrations of nitrogen (N) and calcium (Ca). Treatments included control 1 (without nutrient solution), control 2 (nutrient solution without N and Ca), and the mixtures of...
the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...
Drought stress is a major constraint for crop production in arid and semiarid regions, such as Iran. In this study the effect of 5-aminolevolinic acid (ALA), the new plant growth regulator, on Coriander (Corianderum sativum L.) plants under drought stress was studied. The layout was factorial experiment in randomized complete block design (RCBD) with 3 levels of drought stress including stress-...
introduction: rosemary (rosmarinus officinalis l.) is a perennial, ever green and fragrant plant belongs to lamiaceae family. vegetative parts of this plant have essential oil and compounds with anti oxidant and antibacterial properties which are used extensively in pharmaceutical, food and cosmetic industries. the use of biofertilizers such as vermicompost and nitroxin could have beneficial ef...
