Doses de gesso em mudas micropropagadas de Banana Nanicão cv. Willians

Abstract

This study aims to evaluate the response of micropropagated seedlings of banana cultivars Willians (Musa spp.) to agricultural gypsum levels during the acclimatization period. The experiment was carried out on a nursery and a randomized block design with six agricultural gypsum levels (0, 20, 40, 60, 80 and 100 kg m-3 of substrate) and four replications. During the conduct of the experiment were evaluated the following characteristics: height, stem diameter, leaf area, shoot dry matter, root and leaf dry matter, and Dickson Quality Index. Data were submitted to analysis of variance by F test and agricultural gypsum levels subjected to polynomial regression analysis. The agricultural gypsum levels influenced only the height of the seedlings, without affecting the development and the quality of the seedlings. It was concluded that the addition of agricultural gypsum to the substrate for the production of micropropagated banana seedlings of the cultivar Nanicão Willians does not influence its growth and development.
