مطالعه ذخاير ژنتيكي گل محمدي (rose damascena mill) مناطق مختلف در شرايط آب و هوايي استان خوزستان

The Study Rosa damascene Mill in different area in Khoozestan Province Climate

In this study. 35 Rosa damascena Mill. Genotypes was evaluated based on flower yield and components, phenological and morphological characteristics. The trial was carried out in the fields of Fadak Botanical Garden in Dezful (affiliated to Research Institute of Forest and Rengelands) Iran. The experiment was conducted under design in randomized complete blocksdesign. with three replicates during 2005-2006.Genotypes showed significant differences for flower number per plant, flower number per m . flower yield per plant, petal number, flower fresh weight, flower dry weight, flower diameter, plant height, canopy, leaflet area, leaflet fresh weight, leaflet dry weight and leaflet area/weight ratio (P<0.01). and flower dry matter percentage (P<0.05). The comparison of means was done using Duncanʹs test. The Comparison classified the genotypes in different groups. In correlation analysis showed significant relations between traits important in genotypes (P<0.01). positively correlated (r = 0.97) flower yield with flower number per plant, flower number per plant with flower number m2 (r = 1.00) and plant height with canopy (r = 0.67). The evaluation from obtained results showed variety in flower yield and components between genotypes exsiting in country. The measure flower yield per plant and flower number per plant in the study showed positive correlation and relative significant. It can be used as important traits in evaluation of criterions and selection of genotypes.
