Abstract

Diversity in field bindweed (Convolvulus arvensis L.) populations collected from Karaj, Varamin, and Damavad during 2006 (for seed collection) to 2007 (for seed germination and plant growth in green-house) at the Weed Research Department, Iranian Plant Protection Research Institute for identification of morphophysiological variation using multivariate analysis methods. The most important variables were shoot dry weight, leaf dry weight, and leaf area, respectively. Results showed 11, 15 and 16 biotypes in Karaj, Varamin, and Damavand populations, respectively. Varamin was clustered near to Damavand, but both these populations had significant differences with Karaj population.         

 

Key words: Biodiversity, ecotype, biotype, principal component analysis, cluster analysis, field bindweed, Convolvulus arvensis.
