| Abstract: | A species/provenance trial was conducted with 4 species,Cupressus lusitanica,C.arizonica,C.funebris and C.giganta,and 12 provenances of them.The largest height increment and DBH (diameter at breast height) increment for all species and provenances occurred respectively at the 4th and 5th years after planting.There were significant differences in height and DBH among species and provenances 10 years after planting.Provenances 3,2,6,7 of C.lusitanica displayed the best growth with average height and DBH above 10.4 m and 15.2 cm respectively.Provenance 3 showed the largest height (11.09 m)and provenace 6 showed the largest DBH (16.9 cm),9.9% and 27.1% repectively larger than the height and DBH of C.funebris.Falling-down by wind occurred to all species and provenances.It relates to species,age and site conditions. |
