Kaplanmis Yonca (Medicago sativa L.) Tohumlarinin Kuraklik Stresi Kosullarinda Çimlenme Özelliklerinin Belirlenmesi

At the end of the both experiments, germination rate was calculated and the fresh and dry weight of the shoots and roots, length of shoots and roots were determined. Keywords: Medicago sativa L., seed coating, drought, germination characteristics Extendent Summary Alfalfa (Medicago sativa L.) is an essential hay product and a protein-rich forage crop which grow in arid and semi-arid regions of the world. Six different drought stress levels (0, -2, -4, -6, -8 ve -9.8 bar) were handled in this study and were used Polyethylene glycol6000 (PEG-6000) to create of drought stress at different levels. 50 seeds was laid in each petri dish and placed in germination cabinet (70% humidity, 20 °C temperature 14 hours light (2000 lux) 10 hours darkness). With the increase in the severity of drought stress, the germination, emergence and early seedling growth characteristics of alfalfa seeds were decreased.
