Abstract:: Taking the varieties of Gazania reginsL.‘Xingbai’,‘Hongwen’ and their hybridization ‘XH’ as experimental materials,using electronic balance,transpiration rates of the three varieties cutting seedlings and their branches were determined.Meanwhile,environmental factors,such as light intensity,temperature and atmospheric relative humidity were recorded,and the relation of environmental factors,vegetative organs and transpiration rate in different materials were analyzed.The results showed that there existed significant difference between transpiration rate and different materials,and the biggest average transpiration rate was 300.45 g^.m^-2.h^-1 of ‘XH’ cutting seedlings,while the smallest value was 38.76 g^.m^-2.h^-1 of ‘XH’ branches.Generally speaking,plant transpiration rate,light intensity and temperature were positive correlated,negatively correlated with humidity.And there was a certain relationship between vegetative organs and transpiration rate,but they were not the same in different varieties.By comparing the transpiration rate in different varieties of Gazania regins?L.cutting seedlings,some reference to reduce maintenance cost and water consumption in summer landscaping were provided.
