A multivariate statistical analysis was performed on morphological characters of sixty-one populations of Avena eriantha Dur. A. clauda Dur., A. barbata Pott ex Link., A. wiestii Steud., A. fatua L., A. sterilis ssp. ludoviciana L. and A. sativa L. Factor analysis revealed that intraspecific morphological variations are due to quantitative characters. Interspecific as well as intersectional rel...

Species-specific basic density (BD) data are necessary to improve the indirect methods of biomass determination. The tree components (e.g., bark, branches, roots) is studied much less than that stem wood. Nevertheless, ignoring specific BD values these in calculations can lead errors. study aims investigate variation aboveground and belowground by studying a total 162 gray alder (Alnus incana (...

A comparative analysis of the riparian vegetation dominated by Alnus glutinosa in Italy and Tyrrhenian islands, based on literature data unpublished relevés, is presented. total 456 phytosociological relevés were processed. For definition plant communities alliances, hierarchical clustering was performed using Bray-Curtis coefficient Detrended Correspondence Analysis ordination methods. Identif...

Cys proteinases play important roles in plant cell development and senescence. A cDNA, AsNODf32, obtained by differential screening of a nodule cDNA library of the leguminous plant Chinese milk vetch (Astragalus sinicus), represents a nodule-specific Cys proteinase similar to that reported for the actinorhizal Alnus glutinosa-Flankia symbiosis. A characteristic feature of this proteinase is the...
