摘要
在雷州半岛,以22个桉树无性系为材料,对其2年生时的生长性状进行比较。结果表明,22个无性系的树高、胸径、单株材积和蓄积量上差异显著,综合评价选择出巨尾桉(LL_(126)和G_9)、尾叶桉(G_4、LL_(128)、LL_(125)、LL_(127)和JJ_(19))、尾巨桉(LL_(129))和韦塔桉(JJ_(23)、JJ_(27)和JJ_(28))为优良无性系。
Growth differences among twenty - two 2 - year - old Euca/yptus clones in the I_eizhou Peninsula were analyzed. The results revealed significant differences in tree height, DBH, individual tree volume and stand volume among the 22 clones. From comprehensive evaluation, clones of E.grand/s x E. urophylla (clones LL,, and G9), E. urophylla(G,, LLns, LL125, LL127 and JJ129), E.urophylla x E.graadis(LL129) and E. s (JJ23, JJ27 and JJ28) were selected as the best performing clones. Key words: Euca/yptus ; clone; growth; Leizhou Peninsula
