چکیده مقاله:
Many polymorphisms exist in field bindweed (Convolvulus arvensis L.) populations. These differences that appear especially in their flower and leaf cause to different biotypes of this weed that are different in view of dry weight, rate- and flowering period. This research was accomplished during ۲۰۰۵ to ۲۰۰۶ at Weed Research Department, Iranian Plant Protection Research Institute for identification of morphological and physiological variations of field bindweed population and introduction of these weed biotypes in Varamin. The analysis of the character was done by Principal Component Analysis (PCA) and Cluster Analysis (CA) based upon ۴۳ morphological and physiological variables. The most important variable was Leaf Dry Weight. Results of this experience showed ۱۵ biotypes in Varamin. The variability in morphological and physiological of these field bindweed biotypes may explain their different adaptability as the environmental conditions and different management practices change.
