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...
متن کاملFungal Diversity The endophytic mycobiota of the grass Dactylis glomerata
Fungal endophytes were isolated from asymptomatic and symptomatic plants of Dactylis glomerata sampled in different ecosystems in Spain. Fungi were identified using morphological, as well as molecular methods based on internal transcribed spacer (ITS) and ribosomal DNA sequencing. Molecular data provided a framework for identification and assessing the phylogenetic position of isolates. One hun...
متن کاملEvaluation of Drought Stress Indices in barley ( Hordeum vulgare L . )
In order to evaluation of drought resistant indices in barley (Hordeum vulgare L.), 10 barley genotypes evaluated in Completely Randomized Design with three Replications in two conditions, (under drought stress and in normal with irrigation in planting, flowering and grain filling stages) in Islamic Azad University, Miyaneh Branch Research Farm in 2012. Drought tolerant indices basis of yield p...
متن کاملDrought responsive gene expression regulatory divergence between upland and lowland ecotypes of a perennial C4 grass.
Climatic adaptation is an example of a genotype-by-environment interaction (G×E) of fitness. Selection upon gene expression regulatory variation can contribute to adaptive phenotypic diversity; however, surprisingly few studies have examined how genome-wide patterns of gene expression G×E are manifested in response to environmental stress and other selective agents that cause climatic adaptatio...
متن کاملHaploids in Hordeum Vulgare.
suns. The extension of the Andromeda nebula beyond the photographic limits is presumably typical of what may be found for other such objects. Comparisons with the surface brightness of the galaxy are still hampered by uncertainties in the data for our own system. There may be no part of the galaxy which, seen from outside, would be as bright as the central portion of M 31. In the latter system ...
