Influence of laser beams combined with chemomutagen (MNU) on the variability of traits and mutation frequency in spring barley
combined treatment barley biostimulation mutation laser N-methyl-N-nitrosourea
2008/11/24
Laser light as a pure ecological factor started to be used as a plant biostimulator. It is especially important in the case of short exposures to laser light. However, prolongation of irradiation indu...
Estimation of genetic variability of yielding traits and physical properties of seedsof spring barley (Hordeum vulgare L.) mutants
hull-less barley geometric properties resistance to squashing mutants yield structure
2008/11/19
The material for performed studies comprised 19 hull-less barley mutants, their initial form 1N/86, as well as six hul- led forms – three fodder and three malting cultivars. In field trial the mutants...

Laser is one of the sources for inducing a biostimulation effect and genetic changes in higher plants. Lower doses of laser activate plants, resulting in increasing bioenergetical potential of the ce...
Influence of laser light on leaf area and parameters of photosynthetic activity in DH lines of spring barley (Hordeum vulgare L.)
laser light blade area photosynthetic activity barley
2008/11/18
The initial material for performed studies was constituted by hull and hull-less DH lines of spring barley (Hordeum vulgare L.). The kernels were irradiated with helium-neon laser (He-Ne) in red light...
Response of spring barley to changes of compaction and aeration of sandy soilunder model conditions
soil bulk density oxygen diffusion rate (ODR) root growth yield spring barley
2008/11/18
The response of grain yield and root growth of spring barley to changes of compaction and aeration of a sandy soil was studied under model conditions. The experiment was done using plots of 1 m x 1 m....
