variation in some european pear (pyrus communis l.) seedling rootstock populations using morphological chracteristics
many characteristics of pear trees such as growth, fruit size and yield, are influenced by the genetic characteristic of the rootstocks. in iran, mainly european pear seedlings (pyrus communis l.) are used as the rootstock in the pear orchards. thus, evaluation of pear seedling rootstocks is an important task. this experiment was conducted in 2009 and 2010 growing seasons in order to explore th...
متن کاملHabitat effects on morphological variation of Garra rufa (Heckel, 1843) populations in Iran
Understanding the processes involved in evolution of organisms is a principal topic that has received much attention from the research community. A common way to achieve this is to study the ecological conditions and morphological relationships of taxa. Fish are widely regarded as notable animal models in studies of environmental influence on morphological features given their high environmenta...

متن کاملMorphological variability of the Asiatic cyprinid, topmouth gudgeon Pseudorasbora parva, in its introduced European range.
To assess the spatial variability in external morphology of non-native populations of topmouth gudgeon Pseudorasbora parva within an ontogenetic context, triple regression analysis (distance-based measurements) was applied to data from eight European populations (two Slovak, four Romanian, one English and one French). The data from Slovakia were also subjected to geometrical analysis (co-ordina...
