Abstract
In Australia, the natural distribution of Eucalyptus species is strongly influenced by the resistance of seedlings to drought. Survival strategies in response to water deficit at the initial seedling growth phase have been studied (Bachelard 1986; Wang et al., 1988; Davidson and Reid, 1989; Myers. and Landsberg, 1989; Gibson and Bachelard, 1994; Gibson et al., 1991, 1994, 1995; Lemcoff et al., 1994; Anderson et al., 1996). Some of the adaptive responses to water deficit cause changes in plant structure, growth rates, water use efficiency, tissue osmotic potential and stomatal conductance among others. (Jones, 1992).
在澳大利亚，桉树物种的自然分布受到幼苗抗旱能力的强烈影响。对幼苗生长初期水分亏缺时的生存策略进行了研究(Bachelard 1986;Wang et al.， 1988;Davidson and Reid, 1989;迈尔斯。and Landsberg, 1989;Gibson and Bachelard, 1994;Gibson等人，1991,1994,1995;Lemcoff et al.， 1994;Anderson et al.， 1996)。一些对水分亏缺的适应性反应会引起植物结构、生长速度、水分利用效率、组织渗透势和气孔导度等方面的变化。(琼斯,1992)。
