以库拉索芦荟（Aloe vera（L）Burm f.）及其与形态、生理参数和水分利用效率（作为气生生物量和凝胶产量的函数）的关系。植物受到四个水平的水的可用性相当于20%（T1），15%（T2），10%（T3），和5%（T4）的大气蒸发需求。植物表现出解剖，形态和生理反应，不同的浇水处理。极端处理由于T1水分过多和T4水分不足而产生负响应。处理T2和T3引起细胞特性和生产力的积极响应。解剖结构特征与生理密切相关。气孔数量的增加与叶长、叶宽和叶厚呈负相关（r =-0.85、-0.81和-0.59），与生物量呈负相关（r =-0.84），与角质层厚度呈正相关（r = 0.78）。处理T2表现出最大的生物量生产用水效率（24.6 g L−1），这与细胞大小（r = 0.68）和气孔数量（r =-0.70）密切相关。
The effects of water availability were evaluated on the photosynthetic tissue anatomy in Aloe vera (L) Burm f. and its relationship with morphological, physiological parameters, and water use efficiency as a function of aerial biomass and gel production. Plants were subjected to four levels of water availability equivalent to 20% (T1), 15% (T2), 10% (T3), and 5% (T4) of the atmospheric evaporative demand. The plants exhibited anatomical, morphological, and physiological responses to the different watering treatments. The extreme treatments produced negative responses due to excess water in T1 and water deficit in T4. Treatments T2 and T3 elicited positive responses in cell characteristics and productivity. Anatomical and structural characteristics were closely linked to physiology. Increased stomata number was negatively related to leaf length, width, and thickness (r = −0.85, −0.81, and −0.59, respectively) and to biomass production (r = −0.84), and positively related to the increase of cuticle thickness (r = 0.78). Treatment T2 showed the maximum efficiency of water use for biomass production (24.6 g L−1), which was closely related to cell size (r = 0.68) and number of stomata (r = −0.70).
