Abstract: Germination experiments with fixed temperature show that varieties of Stylosanthes require a temperaturehigher than 15℃ to geminate.The computer simulated model can correctly predict the gemination processunder different temperature regimes.Forage plants treated vvith different temperatures show that Paspalum wettsteinii,P.dilatatum,Setaria anceps cv.Narok and Melinis minutiflora can safely get throughboth winter and summer,but Trifolium, repens can not survive over summer in most areas of Guangdongprovince.Macroptilium atropurpureum and varieties of Stylosanthes such as Graham,Cook,Seca and 184can survive over winter only in restricted areas of the province.The relative electronic conductivity ofleaves after temperature treatment show a close relationship with their injuries caused by te
