摘要

摘要桉树因其对干旱的适应性强,是干旱地区经常种植的植物。此外,它以其众多的物种而闻名,这为选择几种具有不同用途的耐受性物种提供了很好的机会。因此,在以半干旱、干旱和撒哈拉气候为特征的地区和国家,选择抗干旱的物种、杂交种或基因型成为种植前的必要条件。研究表明,干旱对桉树解剖、生理和生化参数有重要影响,水分胁迫直接影响桉树的生长、产量和对害虫的反应。然而,不同物种、基因型、杂交种和无性系对干旱的反应差异很大。这一结果代表了桉树耐受和适应缺水或气候变化的领域。

An overview of adaptative responses to drought stress in Eucalyptus spp.
Abstract Eucalyptus is a plant frequently present and cultivated in arid regions because of its high adaptation to drought. Furthermore, it is known by its numerous species which represents a great opportunity to choose several tolerant species with variable uses. Therefore, the choice of species, hybrids or genotypes resistant to aridity becomes a necessity before any plantation in regions and countries characterized by semi-arid, arid and Saharan climates. Our review shows an important effect of drought on anatomical, physiological and biochemical parameters of Eucalyptus spp. Indeed, water stress acts directly on growth, yield and response to pests. However, the response to drought varies significantly among species, genotypes, hybrids and clones. This result represents a field for the selection of eucalypts tolerant and adapted to water deficit or climate change.
