Abstract
Caragana sinia,belonging to Papilionoideae of Leguminosea,is of great value in vegetation restoration and ecological construction in arid or semi-arid areas.Its seed is naturally hard and dormant.Effects of temperatures and soil moisture on germination of caragana sinia seed are thus researched.The results indicated that the dormancy of caragana sinia seed which had the water content of 1.62%and the dormancy rate of over 95% was broken by boiling water.The suitable temperature for germination of caragana sinia seed was 20~35℃,but variable temperature fails to increase germination.The lowest soil moisture of germination was 3% and the optimum soil moisture was about 6%~12%.
