- Abstract
The objective was to investigate the effect of substrate compositions with and without the addition of controlled release fertilizer (CRF) and to determine the correlations between the morphological characteristics of Agonandra brasiliensis. The variables studied were: shoot height, collet diameter, increase of height of shoot and collet diameter, shoot dry weight, root dry weight, total dry weight, the relation between the dry matter weight of the shoot and the dry matter weight of the roots, the relation between shoot height and collet diameter, the relation between shoot and root dry weight, and Dickson quality index. The results of the total dry weight of the ivorywood plants allowed to infer a positive influence of the addition of CRF in the Sub 1 (8.3 g plant-1), Sub 2 (8.2 g plant-1), and Sub 4 (7.3 g plant-1) showing an increase of 72.2 %, 52.4 %, and 68.5 % respectively, when compared to Sub 1 (2.3 g plant-1), Sub 2 (3.9 g plant-1), and Sub 3 (2.3 g plant-1) without CRF addition. The substrates (sub 5) and (sub 1) with addition of CRF are indicated for the production of seedlings of Agonandra brasiliensis.
