摘  要:
经2002年大雪和2008年冰冻灾害天气后,通过调查,发现尾赤桉、尾巨桉等杂交桉具有较强耐寒能力。在-3℃短时极端低温、0℃以下低温持续2d的灾害天气,海拔500m以下地域,杂交桉仅有轻微寒害。在-4℃短时最低气温和0℃以下低温持续20d的冰冻天气,杂交桉寒害主要表现为机械性损伤,而非生理性冻害,且冰冻后多数能萌芽。选择耐寒品种并在较低海拔种植,在桂林可以发展杂交桉。

摘  要:
Cold damage of Eucalyptus urophylla×E.camaldulensis and E.urophylla×E.grandis after 2002 snow and 2008 frozen cold weather were investigated. The results showed that both hybrids could tolerate cold weather,which they were slightly damaged at temperature below 0℃ for 2 days with extremely low by -3℃ in a short period at an altitude lower than 500 m,and mechanically but not physiologically wounded at temperature below 0℃ for 20 days with extremely low by -4℃ in a short time. Most of individual tree of hybrids could sprout after cold weather,it suggested hybrid eucalyptus could be extended at the low altitude area in Guilin by the cold tolerance species.
