ABSTRACT

Populus euphratica Oliv. is a tree that is strongly resistant to drought and salt stress, which is primarily distributed in arid and semiarid lands. The leaves of the species exhibit a special feature that causes them to be designated as heterophylly. In this brief review, we primarily discuss the heteromorphic leaf development and anatomical features, such as the differentiation of spongy and palisade tissues, in heteromorphic leaves of the species. Furthermore, we also discuss the different physiological characteristics in heteromorphic leaves related to the ecological adaptation of P. euphratica to drought environments. These traits in P. euphratica may help researchers evaluate its ecological value in arid areas and evaluate its scientific merit in understanding the mechanism of development of heteromorphic leaves in plants.

摘要

胡杨。是一棵对干旱和盐胁迫具有强烈抵抗力的树，这种树主要分布在干旱和半干旱地区。该物种的叶子表现出特殊的特征，使它们被指定为杂种。在这篇简短的综述中，我们主要讨论该物种异形叶片中异形叶片的发育和解剖特征，例如海绵状和栅栏组织的分化。此外，我们还讨论了与胡杨对干旱环境的生态适应有关的异型叶片中的不同生理特性。胡杨假单胞菌的这些特征 可以帮助研究人员评估其在干旱地区的生态价值，并评估其在了解植物异型叶片发育机理方面的科学价值。
