INCREASED MEIOTIC IRREGULARITY ACCOMPANYING INBREEDING IN DACTYLIS GLOMERATA L

Increased Meiotic Irregularity Accompanying Inbreeding in Dactylis Glomerata L.

In vitro SCREENING FOR RESISTANCE TO PROLINE ANALOGUES IN ORCHARDGRASS Dactylis glomerata L

Plant regeneration capacity of orchardgrass leaf explants cultured in vitro in the presence of 0.01, 0.1, 1.0 and 10.0mM hydroxyproline (Hyp) or azetidin-2-carboxylic acid (A2CA) was determined. Hyp inhibited to a lower extent than A2CA formation of somatic embryos, respectively plants. Hyp also induced relatively insignificant changes of free amino acid content in the leaves of the regenerants...

Identification of orchardgrass (Dactylis glomerata L.) cultivars by using simple sequence repeat markers.

The accurate identification of orchardgrass (Dactylis glomerata L.) cultivars is necessary to ensure purity for consumers, the effective utilization of cultivars, and to protect the intellectual property for breeders. Therefore, this study aimed to use SSR to construct DNA fingerprinting of orchardgrass cultivars. The genetic diversity of 32 orchardgrass cultivars originated from 21 countries, ...

Combining Drought Survival via Summer Dormancy and Annual Biomass Productivity in Dactylis glomerata L.

Under Mediterranean climates, the best strategy to produce rain-fed fodder crops is to develop perennial drought resistant varieties. Summer dormancy present in native germplasm has been shown to confer a high level of survival under severe drought. Nevertheless it has also been shown to be negatively correlated with annual biomass productivity. The aim of this study was to analyze the correlat...

Arabinogalactan Proteins in Salt‐adapted Suspension Cultures of Dactylis Glomerata L

Arabinogalactan-proteins (AGPs) are widely distributed in higher plants and play multiple roles in various processes associated with plant growth and development, including cell expansion, cell proliferation and embryogenesis. Soluble extracellular AGPs are also abundant in the growth medium of suspension. Levels of cell wall bound and extracellular AGPs were measured spectrophotometrically usi...
