This study was conducted to evaluate the effect of hydropriming and seed aging on germination and enzymatic properties of pinto bean under salinity stress as factorial based on a completely randomized design with four replications. Two groups of seeds (i.e., non-aged and aged seeds), two hydropriming treatments (i.e., hydro primed and unprimed seeds) and six salinity treatments (i.e., 0, 2, 4, ...

Coumarins are regarded as a class of plant secondary metabolites of phenyl propanoid group distributed in Apiaceae family. The simple coumarin is the first compound of the class. In the present work, allelopathic potential of coumarin on Lactuca sativa cv.siahoo from physiological and biochemical aspects, was investigated. At first stage, the effects of different concentration of the compound o...

Chalcone is regarded as a common secondary metabolite in plant represented as precursor of flavonoids. In the present work, the effects of different concentrations of chalcone (1, 10, 100, 1000µg/mL) on lettuce seed germination and seedling radicle and gemule were evaluated to determining optimal experimental dose of the compound. The concentration of 100 µg/mL of chalcone were dete...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

In order to investigate the effects of sowing date on yield and some agronomic traits of six forage maize hybrids, two experiments were conducted in 2009 in two locations including Rasht and Fuman. The experimental design was randomized complete blocks with factorial arrangement and three replications. Treatments consisted of three levels of sowing date (31 May, 13 and 26 June) and six maize hy...
