ABSTRACT: The work aimed to study the development of Tabebuia chrysotricha Standl. seedlings in function of different substrateand different fertilization solutions. To compose the substrate it was used fibrous and granulated coconut fiber obtaining the followingtreatments: S1- 100% fibrous, S2- 60% fibrous and 40% granulated, S3- 40% fibrous and 60% granulated and S4- 100%granulated. The basis fertilization was the same for all treatments and the solutions of fertilization varied in order to obtain solutionswith the following electric conductivities: EC1- 1.06 dS m-¹, EC2- 2.12 dS m-¹, EC3- 3.2 dS m-¹ and EC4- 4.25 dS m-¹. The propagativematerial was sowed directly in plastic containers (120mL) with the respective substrates. The fertilization was received through subirrigation once a week, until the seedlings reached 20cm of height approximately. The chemical analyses of the substrate (EC and pH),through aqueous extraction method 1:1.5 (1 substrate: 1.5 deionized water), the analyses of aerial part height, stem diameter andpairs true leaves number, as well as the weight of total dry matter, were accomplished each 15 days. In almost every analysis, thesubstrate with granulated coconut fiber, as well as the smallest EC (1.06 e 2.12 dS m-¹) of fertilization solutions, formed seedlings withhigher averages, indicating faster growth. In the conditions of this experiment, the production of T. chrysotricha seedlings was betterin granulated coconut fiber substrate and fertilizer solutions with EC of 1.06 dS m-¹, appreciating the estimated characteristics. |
