Abstract:
Jinggang No.1 was selected from an Eucalyptus grandis plantation after severe frost bite and was propagated by tissue culture. It was tested at several sites with E. dunii, E. camalduensis, E. grandis clone Eg5, E. grandis × E. urophyla clone Guanglin 9, E. grandis × E. camalduensis clone DH201-2 and E. grandis × E. urophyla clone DH3229 as controls. Based on growth measurement, cold-resistance evaluation, snow pressure resistance investigation and tests of common pests and diseases, its growth, adaption capacity and cultivation prosperity were evaluated. The results showed that its cold resistance was close to that of E. dunii and E. camalduensis, the snow pressure resistance was stronger than that of E. dunii and DH3229, the preserving rate, height growth and diameter growth were higher than those of E. dunii, E. camalduensis and Eg5.
