in this research, the antagonistic effects of bacillus subtilis isolates against the causal agent of tomato damping-off, rhizoctonia solani were surveyed under laboratory and greenhouse conditions. isolates b4 and b18 showed the most inhibition ratio in the volatile and non-volatile metabolites tests which were 50.3% and 58.6% respectively. the six out of 25 isolates studied more and their anta...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
چکیده مورچهها با حمایت از شپشکها در مقابل دشمنان طبیعی، میتوانند برنامههای کنترل بیولوژیک آنها را مختل نمایند. طی سالهای 1389 و 1390 با نمونهبرداری از باغات مرکبات شهرستانهای ساری و بهشهر، فون و فراوانی نسبی مورچههایِ همراه با شپشکها مورد مطالعه قرار گرفت. همچنین، تاثیر تراکمهای مختلف کاست کارگر گونهی santschi lasius turcicus بر میزان تغذیه و فراسنجههای واکنش تابعی حشرات ماده و لا...
A greenhouse factorial experiment was conducted in completely randomized design (CRD) with three replications to investigate the effect of soil Zn deficiency stress on the expression of three genes involved in the synthesis of metal chelating agents (NAS1, NAS2 and NAS3) in bread wheat. Hamoun and Hirmand (Zn-efficient and inefficient cultivars, respectively) cultivars were planted under Zn def...
To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
abstract this thesis includes five chapter : the first chapter assign to establish fuzzy mathematics requirement and introduction of liner programming in thesis. the second chapter we introduce a multilevel linear programming problems. the third chapter we proposed interactive fuzzy programming which consists of two phases , the study termination conditions of algorithm we show a satisfac...
In this research work the relative resistance of rice (Oriza sativa L.) cultivars to the Blast disease, resulted by the fungi Magnaporthe grisea Sacc. was determined using their progressive disease curve. Fifty eight internal cultivars and the line of Omidbahksh were tested under greenhouse and field conditions. Phenotyping tests were conducted on blast nursery uisng a randomized complete bloc...
