Trial of Eucalypt Species/Provenances in the East Part of Hainan Island

The results of species/provenance trial involved 11 species and 79provenances at 5-year-old in the east part of Hainan Island showed that the growth differences among 79 provenances within the different species were highly significant while thegrowth differences among provenances within the same species were also highly significant.The ratios of the best provenance and the worse ones on volume per hectare for E.urophylla,E.tereticornis,E.camaldulensis and E.grandis were respectively 8.46:1,5.86:1,5.32:1and 4.03:1.The height growth,DBH and volume per hectare of E.tereticornis,E.camaldulensis and E.grandis were respectively significant and there were negative correlations with the latitude of native habitat while the height growth,DBH and volume perhectare for E.urophylla was highly significant and with negative correlations with the altitude of native habitat.The paper have put forward some other species and provenances suitable for planting in the east part of Hainan Island.
