بررسي تاثير شوري بر جوانه زني توده محلي و رقم اصلاح شده گياه دارويي رازيانه (.Foeniculum vulgare Mill) در شرايط مختلف محيطي

The study of the effects of salinity on germination of introduced and native seeds of fennel (Foeniculum vulgare Mill.) in different conditions

The effects of salinity and seed origin on germination and seedling growth of fennel (Foeniculum vulgrae Mill.) were investigated under different conditions in Azad university branch of Shahr-e-Rey branch in 2006-2007. The conditions included Petri dish in germinator, pots in laboratory and environment. The treatments included 0, 30, 60, 90, 120 and 150 m/mol NaCl also two types of seed origin (introduced and native seeds). Each trial carried out in factorial design based in randomized complete block design with four replications. In the Petri dish condition, germination, vigor, root and shoot length, wet and dry weight of seedling investigated. The results showed that, the effects of salinity and seed origin on the characteristics were significant. The salinity effects on pots in laboratory and environment condition were palpable to the Petri dish in germinator. Also, the native seeds had more resistance to the salinity.
