“…In the second factor flowering date, GDD and oil yield had higher were accounted for 18% of total variation. Similar to our result, Kazemi, Sonboli, Zare & Kazempour (2014), using cluster analysis in Tanacetum aureum, T. oligocephalum and T. heimerlii well differentiated the accessions into separate species. Similarly, Alizadeh & Jafari (2016), in cluster analysis for grouping of the accession of Anthemis triumfettii (L.) DC., Anthemis tinctoria L., Anthemis haussknechtii Boiss.…”

In order to investigate diversity and explain the relationships of essential oil yield with morphological traits, 84 populations T. polycephalum, were sown in the field using randomized complete blocks design (RCBD) with three replicates in Research Institute of Forest and Rangeland, Tehran, Iran in 2013-2014. Data were collected for flowering date, growth degree days (GDD), stem number, plant height, dry matter (DM) yield, essential oil percentage, and essential oil yield. The relationships among traits were determined using correlation, regression and factor analysis. The genetic distance and genotype classification were determined using cluster analysis. DM yield was positively correlated with plant height, canopy cover, stem number and oil yield (ρ<0.01), whereas oil% was negatively correlated with plant height and stem number (ρ<0.05). Result of stepwise regression in which essential oil yield were considered as dependent variable showed that essential oil%, and DM yield accounted for 39.95 and 47.75%, of the total variations in essential oil production, respectively. In factor analysis, the Eigen values obtained from 1 to 3 factors were higher than one with 88.9% of total variations. In the first factor, traits of DM yield, plant height, canopy cover, stems number, and in the second factor flowering date, GDD and oil yield and in the third factor oil% had higher Eigen vector coefficients for genotype classification. In cluster analysis, genotypes were categorized in four groups. According to the obtained results, cluster 1 for early maturity, clusters 3 for plant height canopy cover, stems number, DM yield and essential oil production and cluster4, for essential oil%, had significantly higher mean values than other groups. There was a good agreement between the results obtained from cluster and factor analyses in scatter diagram representation of 84 genotypes based on the first and second factors. It was concluded that population of cluster 3 are capable to breeding improved new cultivars and should be focused on selection higher aerial biomass yield, plant height, flower number, essential oil%, coupled with early flowering date.Key words: Early flowering date, genetic variation, phenotypic correlations, morphological traits, plant genetic resources. ResumenPara investigar la diversidad y explicar las relaciones del rendimiento de aceite esencial con rasgos morfológicos, 84 poblaciones de T. polycephalum fueron sembradas en el campo utilizando diseño de bloques completos al azar (BCA) con tres réplicas en el Instituto de Investigación de Bosques y Pastizales, Teherán, Irán en 2013-2014. Los datos fueron colectados para la fecha de floración, días de grado de crecimiento (DGC), número de tallos, altura de planta, rendimiento de materia seca (MS), porcentaje de aceite esencial y rendimiento de aceite esencial. Las relaciones entre las características agronómicas se determinaron mediante correlación, regresión y análisis factorial. La distancia genética y la clasificación del genotipo, se determinaron...

To evaluate the seven species of Tanacetum genus -Tanacetum balsamita, T. parthenium, T. pinnatum, T. polycephalum, T. tabrisianum, T. uniflorum, and T. vulgare -an experiment was conducted in Karaj Iran. Data were recorded for plant canopy cover, plant height, flower number per plant, aerial biomass yield, time required for flowering, growing degree days to flowering (GDD), essential oil percentage and yield. Results showed that T. parthenium had higher mean values for plant canopy cover, plant height and flower number per plant whereas the species of T. parthenium, T. balsamita and T. vulgare had higher aerial biomass yield in comparison to the other species. The T. balsamita coupled with aerial biomass yield had the highest essential oil concentration. The T. tabrisianum and T. uniflorum were earliest ripening species due to lowest GDD. Essential oil yield was positively and significantly correlated with the traits that are components of aerial mass, indicating that selection for breeding new cultivars should focus on increased aerial biomass yield, late flowering and high flower number.

A phytochemical investigation of extracts from flowers and aerial parts of Tanacetum sonbolii afforded 7 new germacranolide sesquiterpene lactones. The structures were established by a combination of 1- and 2-dimensional nuclear magnetic resonance spectroscopy, high-resolution mass spectrometry, and electronic circular dichroism. The in vitro antiprotozoal activity of the compounds against Trypanosoma brucei rhodesiense and cytotoxicity against rat myoblast (L6) cells were determined. Compounds 4 and 5 showed IC50 values of 5.1 and 10.2 µM and selectivity indices of 3.9 and 4.0, respectively.
