Effects of Temperatures on the Seed Germination of Different Varieties of Carthamus tinctorius L.
The aim was to investigate the effects of temperature on seed germination of different varieties of Carthamus tinctorius L.[Method] Selecting Yumin Wuci,Xinhong No.4,Jihong No.1 as test material,germination test was conducted under different temperature.[Result] The seed germination of C.tinctorius is significantly impacted under different temperatures.The seed germination rate is high during 5-25 ℃,highest germination rate is under 10 ℃ with germination rate 87.89%.In view of difference of ground temperature and atmosphere,optimum temperature range of C.tinctorius seeding is 10-15 ℃.[Conclusion] Cultivating C.tinctorius L.should select proper variety according to local climate conditions.
