laser is one of the sources that induce a biological effect in higher plants. the positive effect of laser on some crops has been proved. this research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (triticum aestivum cv. kavir) under different nacl treatment levels. semi-coherent red beam, infrared beam and one-second harmonics of neodymiu...

materials and methods a total of 40 different bread types such as barbari, sangak, lavash, and baguette produced in 124 bakery shops in rasht city were analyzed for some heavy metals (as, cd, pb, cr, ni, and co) by inductive coupled plasma (icp) instrument (icp-qes). results the mean content of the as, cd, and pb in different breads were respectively as follows: barbari, 0, 0.73, and 0.07; sang...

In recent years, the number of wheat, Triticum aestivum L., fields heavily infested by Hessian fly, Mayetiola destructor (Say), has increased in the Great Plains of the United States. Historically, resistance genes in wheat have been the most efficient means of controlling this insect pest. To determine which resistance genes are still effective in this area, virulence of six Hessian fly popula...

Currently, economic, agronomic and environmental concerns lead to reduce the use of herbicides. Mechanical weeding can help to reach this objective. Dynamics and biology of wild chamomile (Matricaria chamomilla L.) populations were assessed as well as dynamic of winter wheat (Triticum aestivum L.) for four level of application of a weeder-harrow (0, 1, 2, 3 treatment(s)). After each treatment, ...
