Abstract

Purple coneflower as top-selling medicinal plant is widely used in Europe and North America for thetreatment of common cold. This experiment was conducted as a randomized complete block design insplit plot arrangement with three replications in Research Farm of Genetics and AgriculturalBiotechnology Institute of Tabarestan in 2012-13. Experimental treatments included three transplantingdates (April 9, May 9 and June 8, 2013), and three plant population densities (7, 10 and 16 plant/m2)which considered as main and subplots, respectively. Results showed a relative compensatory effect ofhigher population density until 10 plants/m2, however, delayed planting resulted to decrease in total shoot, leaf (L) and STEM (S) dry weights. It represents that the highest flower (F) dry weight (27. 1 g/plant) wasrelated to planting on May 9 with 10 plant/m2 density. Ratio of L/shoot was greater than S/Shoot thanF/shoot dry weight. The highest (L+F)/Shoot ratio was related to the April and May PLANTING DATEs whilethe highest S/Shoot ratio was related June’ s PLANTING DATE. Maximum total PHENOL CONTENT of leaves (51. 1mg of GAE/ g dry matter) and STEMs (35. 9 mg of GAE/ g dry matter) were measured in plants cultivatedon April 9 with a density of 10 plant/m2. The highest total phenolic content of flowers (56. 5 mg of GAE/g dry matter) was determined in plants cultivated on May 9 with a density of 10 plant/m2. Total phenol offlowers was greater in leaves than STEMs. Overall, it could be concluded that early planting of purpleconeflower on April 9 with 10 plant/m2 density was suitable for leaf and STEM dry weight and total phenolproduction, while the delayed planting until May 9 with a population density of 10 plant/m2 was favoritefor flower as production of dry weight and total phenol, according to the experiment conditions.
