for half a century, the limitations of obtaining cross-combinations in lilies because of the incompatibility and incongruity between different varieties have been known. somatic hybridization is one of the most powerful tools for achieving distant interspecific hybrids. for this purpose, protoplast preparation is a first and important step in efficient system for the regeneration of plants from...

To regenerate auxotrophic mutants of Physcomitrella patens, two media of increasing complexity were developed. The survival rate of protoplasts was around 30% higher on full medium when compared to standard minimal medium. Protoplast survival was higher in a medium containing 2.5 mmol/L ammonium tartrate compared to a medium with 5 mmol/L of this compound. Solid medium had a positive effect on ...

trichoderma is one of the important biocontrol agents for certain plant disease that control with different mechanisms. this fungus similar to other biocontrol agents is under the influence environmently factors. medium is one of these factors. this study was investigated effect of the medium (mol.c.b.m.) containing sugar beet molasses, corn steep liquor, baker’s yeast and malt extract as the l...

Description in terms of physicochemistry and heat and mass transfer of the combustion front propagation in a reactive porous medium remains a challenge to science. The literature about this subject distinguishes two types of problems. The first considers only combustion of the gas phase inside an inert solid porous medium. In the second type, the solid phase reacts with the gas phase; Chemical ...
