Pineapple (Ananas comosus L., Merril) is a tropical climate plant of great economic importance for Brazil, the third largest world producer. The study on acclimatization of pineapple micropropagated seedlings is still scarce, with few studies related to the published theme, therefore, the present study aimed to evaluate adaptation of micropropagated seedlings of the cultivars BRS Imperial and BRS Vitória in the municipality of Confresa-MT. The project was carried out in the shade house of the IFMT Campus Confresa, where the planting was carried out in plastic bags, with a mixture of substrate and sand. The experimental design used was completely randomized, with two treatments and twenty repeated. The treatments were the cultivars BRS Imperial and BRS Vitória. Between the months of November 2019 and July 2020, measurements of plant height were collected, observing the development of seedlings in relation to adaptation to the climatic conditions of the region and resistance to diseases. The seedlings were fertilized with N-P-K diluted in water and foliar fertilizer; irrigation was carried out according to the needs indicated by Irrigás. There was adaptability for both pineapple seedlings, with BRS Imperial showing lower growth and greater resistance todiseases compared to the seedlings of BRS Vitória.
