Abstract

Most of the range and fallow lands in Iran are located in cold regions. Annual medic species are important forage plants for introducing to such regions. Low temperatures at late winter and early spring are a main preventive factor for enough forage production.Effects of chilling temperatures on vegetative growth were studied in nine genotypes of five annual medic species (Medicago rigidula, M. radiata, M. orbicularis, M. trancatula and M. polymorpha). The experiment was conducted in a split plot experimental design. The tempreture (0,5, 10, 15, 200e and glass- house 18-25oC) was the main factor and the nine annual medic genotypes were minor factors. The experiment was carried out in growth rooms at aqua culture condition.Plant height, shoot and root dry matter yields and root length were significantly different at various Plants showed better performance at glass-house. In growth rooms, plant height, shoot and root dry matter at 15oe and root length at woe had better performance than other temperatures. In gereral, M. trancatula was the most cold sensitive and M. rigidula, was the most cold tolerant species. No significant differences were observed among temperatures and genotypes after 15 day cold treatments.Regarding great number of accessions and annual medic species in Iran and, considerable inter- and intra- genetic variation among various characteristics are promising for improvement of appropriate varieties adapted to different environmental conditions.
