Casuarina Provenance Test

In each of the three sites located at three provinces,48 provenances of three species were tested. The results showed that Casuarina equsetifolia at the age of five was superior,in growth,to both C. cunninghamiana and C. glauca,and the growth variation among provenances within each of the species was significant.Some provenances, such as C-1,C-3 and 14233 from C. equsetifolia and 13513 from C. Cunninghamiana grew well at all three sites,but 14233 and C-3 were poor in resistance to wind. The provenances of C. cunninghamiana had better adaptability to different sites.
