Banana is among the world´s most popular fruits and it is consolidated in the international market. The largest abiotic constraint threatening banana production is water stress, in rainfed area, judicious use of water is essential for increasing the area under crop production with inadequate water supply. Under such situation the uses of moisture conservation measures are essential, such as the use of mulching of organic materials and synthetic materials. The objective of this study was to investigate the effect of different mulches types in physiological and anatomical characteristics of banana 'BRS Platina' in a non-irrigated management. The experiment was conducted on a farm, located in the city of Lavras. The treatments were: black polyethylene films, double-sided polyethylene films (white and black), organic mulch and control (bare soil). The analyzes performed in the first and second crop were: anatomical analyses, gas exchanges, chlorophyll content, relative chlorophyll index, relative water content, and protoplasmic tolerance. Correlation analysis evidenced the association between yield parameters photosynthetic rate, and stomatal conductance, with high and medium correlation values respectively. Correlations were also observed between chlorophyll a and b, and number of fruits, and number of hands, with high and medium correlation values respectively. Both organic and inorganic (plastic film) mulch are efficient in increasing chlorophyll content and gas exchanges characteristics, but do not influence the anatomical characteristics, relative water content, and protoplasmic tolerance in the first and second crop. Both organic and inorganic (plastic film) mulch can be used in the cultivation of banana 'BRS Platina' under non-irrigated management.

香蕉是世界上最受欢迎的水果之一，并在国际市场上得到巩固。威胁香蕉生产的最大非生物制约因素是缺水，在雨育地区，明智地用水对于在供水不足的情况下增加作物生产面积至关重要。在这种情况下，使用保湿措施是必不可少的，例如使用有机材料和合成材料的覆盖物。本研究的目的是调查不同覆盖物类型对香蕉“BRS Platina”在非灌溉管理中的生理和解剖特征的影响。该实验是在位于拉夫拉斯市的一个农场上进行的。处理方式为：黑色聚乙烯薄膜、双面聚乙烯薄膜（白色和黑色）、有机覆盖物和控制（裸土）。在第一批和第二批作物中进行的分析是：解剖分析、气体交换、叶绿素含量、相对叶绿素指数、相对含水量和原生质耐受性。相关分析证明了产量参数光合速率和气孔导度之间的关联，分别具有高和中等相关值。还观察到叶绿素之间的相关性a和b，以及水果数量和手数，分别具有高和中相关值。有机和无机（塑料薄膜）覆盖物均能有效提高叶绿素含量和气体交换特性，但不影响第一季和第二季作物的解剖学特征、相对含水量和原生质耐受性。有机和无机（塑料薄膜）覆盖物均可用于在非灌溉管理下种植香蕉“BRS Platina”。
