Effects of seed mocturity,the color of testa and GA3 on seed germination of Uraria crinita were investigated.The seeds were plated in the Artificial Climate incubator of 15 ℃,20 ℃,25 ℃,30 ℃,35 ℃,and the germination percentage was 0,6%,8.67%,14%,8%,30 ℃ respectively.The seeds germination rate reached the largest at 30 ℃,so 30 ℃ was the optimal temperature for germination.The testa could inhibit germination,and the germination rate increased 13.33% after removing testa.According to the color of testa,the seeds were divided into three groups:red brown,orange,yellow Green,and germination percentage was 0%,30.6% and 14%,respectively.The illumination could improve germination,so the seed germination required light.GA3 had some effect on seed germination,and the germination rates were 20.67%,12.00%,13.33%,12.67%,8.67% in 100,200,300,400,500 mg/L GA3 treatments,respectively.
