Tolerance of temperature extremes under drought: linking physiological processes with morphological constraints on leaf function

严寒影响了澳大利亚70%以上的地区。每年霜冻对农业和林业造成巨大损害。我们将研究如何减少液压导管直径增加本地木本植物的抗冻性和量化的影响，这种宽容的生产力的叶子。研究结果在当前和未来气候情景下管理温带木本植被中具有应用价值。通过提高对冷冻过程中叶片中水的行为的理解，我们将有助于改进冷冻过程中生物组织中的物理应力和应变模型，这些模型在农业，医学和保护方面重要的生物材料的低温储存中得到应用。

Freezing temperatures affect over 70% of Australia. Each year frosts cause substantial damage to agriculture and forestry. We will examine how decrease in hydraulic conduit diameter increases freeze tolerance in native woody species and quantify impacts of this tolerance on productivity of leaves. The results have application in managing temperate woody vegetation under current and future climate scenarios. By improving understanding of the behaviour of water in leaves during freezing, we will contribute to improved models of physical stresses and strains in biological tissues during freezing, which find application in cryo-storage of biological materials important in agriculture, medicine, and conservation.
