بررسی اثر وزن بنه و کودهای آلی و شیمیایی بر برخی شاخص‌های مورفولوژیکی گیاه دارویی گل حسرت (Colchicum kotschyi) در شرایط زراعی

Soranjan (Colchicum) is a medicinal plant that is effective for rheumatic complaints such as rheumatism, gout and cancer. Iran is a very rich source for many species of Colchicum. In order to evaluate the domestication and adaptation ability of Colchicum kotschyi under field conditions and the effect of nutritional factors on morphological characteristics of plant, a field experiment was conducted as factorial layout based on a randomized complete block design with three replications and 16 treatments at Research Station, Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, in years 2012- 2013. The experimental treatments were corm size (more than 40g and less than 40g), cow manure (0, 50 t/ha), nitrogen fertilizer (0, 50 kg/ha) and superphosphate fertilizer (0, 25 kg/ha). The results showed that the biggest corm size, the most leaf dry weight, capsule and seed weight and seed number per plant were observed under combined biological and chemical treatments. Also, the biggest daughter corms, the most leaf dry weight, capsule and seed weight and the most number of capsules and seeds belonged to mother corms of > 40 grams.
