摘要：The growth performances of 17 provenances of 3 Acacia species,2 provenances of Casuarina species,and 2 provenances of Eucalyptus species were analyzed.The results showed that there are very significant differences among provenances in tree height,crown diameter,ground diameter and reserving rate.All the indicators except reserving rate were remarkably different among blocks.For 17 Acacia provenances,the difference in tree height,crown diameter and ground diameter among provenances and blocks were very significant,but no difference existed between the 2 Casuarina provenances in tree growth.By 18 months’ analysis and Ducan test,the 21 provenances were divided into 3 groups,in which 2 Casuarina provenances,2 Eucalyptus provenances and 2 Acacia provenances had the best growth performance and could be selected as the optimal provenances to plant in hot and arid valley.
