مطالعه بوم شناسی فردی گیاه کمای سازویی در استان خوزستان، ایران

In order to study of ecological and phenological traits of Ferulago angulata asan important medicinal plant, this research was conducted in Hezar Mountains andBondareh Henza in Kerman province, Iran. Random samples of this plant were taken andtheir vegetation habitat conditions and their growth characteristics including height ofcollar leaves, height of flower stem, flower stem number and forage production wererecorded and categorized. Physical and chemical soil characteristics (soil texture, acidity,soil Electrical Conductivity (EC), absorbable phosphorus and potassium, and the percent oforganic carbon) were examined by monthly interval at a soil depth of 30 cm from March toSeptember. All characteristics were analyzed using factorial experiment with two factors ofsites and months. Results showed that this species grow quite satisfactorily in the foothillselevation of 2750 m to 3540 m above sea level as long as it received more than 200 mmannual precipitation. The soil EC was less than 1 ds/m and acidity was ranged from 7.5 to7.8. Canopy cover in Henza and Babzangi were 15.7% and 6.1%, respectively. Resultsshowed that growth indices as height of collar leaves and forage production were high atthe Babzangi sites, while the height of flower stem was important in Henza. Forphenological process, the results indicated that plant germination started from the end ofMarch-April and continued to the end of summer; flowering started from May-June;seeding completed in June-July and dried out completely by end of summer. Moreover inwinter, the plants were dormant.

Ecological and Phenological Study on Ferulago angulata in the Hezar Mountains and Bondar Henza, Kerman, Iran

In order to study ecological and phenological traits of Prangos ferulacea as an important medicinal plant, this research was conducted in Barzok Mountains and Naragh in Esfahan province, Iran. Random samples of this plant were taken and their vegetation habitat conditions and their growth characteristics including height of collar leaves, height of the flower stem, flower stem number and forage production were recorded and categorized. Physical and chemical soil characteristics (soil texture, acidity, soil Electrical Conductivity (EC), absorbable phosphorus and potassium, and the percent of organic carbon) were examined by monthly interval at a soil depth of 30 cm from March to September. All characteristics were analyzed using factorial experiment with two factors of sites and months. Results showed that this species grow quite satisfactorily in the foothills elevation of 2750 m to 3540 m above sea level as long as it received more than 200 mm annual precipitation. The soil EC was less than 1 ds/m and acidity ranged from 7.5 to 7.8. Canopy cover in Naragh and Barzok were 15.7% and 6.1%, respectively. Results showed that growth indices as the height of collar leaves and forage production were high at the Barzok sites, while the height of flower stem was important in Naragh. For phenological process, the results indicated that plant germination started from the end of March-April and continued to the end of summer; flowering started from May-June; seeding completed in June-July and dried out completely by the end of summer. Moreover, in winter, the plants were dormant.
