Evening primrose (Oenothera biennis L.) is a wild flower with high and valuable oil content. High seedshattering, indeterminate inflorescence and heterogeneous germination limit the commercial cultivation ofthis plant. Besides agronomical research, breeding programs can also remedy the above mentioned problems.Since traditional breeding methods take a long time, using techniqu...

The most effective control of Bean common mosaic virus (BCMV) and necrosis (BCMNV) is achieved by using the seeds resistant cultivars. During conventional breeding, resistance against BCMV BCMNV in bean can be developed pyramiding strain-nonspecific dominant I gene with strain-specific recessive (bc-) genes for long-term control. In this study, a total 58 genotypes involving registered green dr...

Induced hairy roots by Agrobacterium rhizogenes are suitable organs for the production of secondary metabolites, due to the stability and high production of roots without phyhormones in a short time. Fenugreek (Trigonella foenum– graecum L.) is one of the most important medicinal plants with valuable medicinal compounds. For optimizing the hairy root induction of T. foenum-graecum L., six strai...
three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
