Abstract: Some wood properties of Eucalyptus exserta, E. citriodora and three hybrids planted in Leizhou peninsula were tested and the wood properties of E. citriodora proved the best.E. exserta originated both from sprouts and seeds and three types (concave dish, convex dish and flat dish of the fruit) of two hybrids were tested. Other factors affecting wood properties were also studied, notably the two types of soil on which the htrees had been growing; lateritic red soil and yellow red latosal. Variance analyses of fiber length, basic density and compression strength parallel to grain Were made and results showed that there exist neither significant differences between the wood properties of the E. exserta from two different origins, nor significant differences among the properties of the three types of two hybrids and that the wood properties of the E. exserta grown on lateritic red soil are superior to those of E. exserta grown on yellow red latosal, though the basic density and the compression strength parallel {9 grain of the trees originated from seed did not reach statistical significance.
