Laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant Lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. Factors evaluated were Lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 dS cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). The maximum germination in salinity stres...

Many polymorphisms exist in field bindweed (Convolvulus arvensis L.) populations. These differences that appear especially in their flower and leaf cause to different biotypes of this weed that are different in view of dry weight, rate- and flowering period. This research was accomplished during 2005 to 2006 at Weed Research Department, Iranian Plant Protection Research Institute for identifica...

abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...

The aim of this study was to evaluate the effect of bronchial asthma on sexual maturation of girls. The study encompassed 111 girls aged 8-17 years (58 girls treated for bronchial asthma and 53 healthy girls). The assessment of girls' sexual maturation has been performed using the Tanner-Marshall scale, determining stages of the development of secondary gender characters - mammary gland (Thelar...

Four thorium sulfate compounds have been synthesized and characterized. [Th(SO4)2(H2O)7] 2H2O (ThS1) crystallizes in space group P21/m, a1⁄47.2488(4), b1⁄412.1798(7), c1⁄48.0625(5) Å, b1⁄498.245(1); Na10[Th2(SO4)9(H2O)2] 3H2O (ThS2), Pna21, a1⁄417.842(2), b1⁄46.9317(8), c1⁄427.550(3) Å; Na2[Th2(SO4)5 (H2O)3] H2O (ThS3), C2/c, a1⁄416.639(2), b1⁄49.081(1), c1⁄425.078(3) Å, b1⁄4 95.322(2); [Th4(SO...

Little seed canary grass (Phalaris minor L.) is a major weed in wheat fields in some parts of Iran. To evaluate the efficacy of molecular and greenhouse methods in detecting the resistance of 49 biotypes of canary grass(Phalaris. Spp) to acetyl-CoA carboxylase-inhibiting herbicides, two methods including whole plant screening and PCR-based molecular methods were applied. Results showed that the...

laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...

background: although many experimental studies provide convincing evidence that type ii immunity is protective against helminths, recent data in mice demonstrate that th1 is also impor-tant in some cestodes like hymenolepis nana. objective: to identify the role of th1 and th2 lymphocytes in immunity against h. nana, the levels of il-12, ifnγ, il-5, and il-13 were de-termined in serum of humans ...
