Abstract
Seeds of eight populations of Anthemis pseudocotula Boiss., A. tinctoria L. and A. triumfettiiL. were cultivated as single plant by using three replicated split plot design for planting date as main factor and the populations of three species as minor factor on the basis of randomized block design on two dates (May, and July). The study was conducted at Alborz Research Station in 2011. Each experimental unit included six rows with a distance of 50 cm and 10 plants per row, with a distance of 40 cm. During the growth period, the traits of crown length and width, plant height, number of flowers, fresh and dry weight were evaluated for the populations of three species. Analysis of variance showed that there were significant differences between two dates of cultivation (p<0.05), as well as among populations and their interaction effects (p<0.01) for all traits. Mean comparison of traits showed that crown length and width, plant height, number of flowers, fresh and dry weight of Anthemis pseudocotula were higher as compared to Anthemistinctoria and A. triumfettii. According to the obtained results, the vegetative and generative traits of Anthemis pseudocotula from 20172-Golestan population were superior as compared to other populations. However, no significant differences were found for the populations of Anthemis tinctoria. Our results clearly showed that Anthemis pseudocotula had lower GDD as compared to other species and flowered earlier. The percentage of essential oil ofAnthemis tinctoria was higher thanthat ofAnthemis pseudocotulaandAnthemistriumfettii.
