Resumo: This work aimed to evaluate the suspended production of rubber-tree rootstocks with substrate in fertirrigation. Treatments were four types of nutritional solutions in completely randomized experimental design, with 5 repetitions. Fertigation was held every two days, using 200 mL of the solution by container. We evaluated plant height, stem diameter (5 cm above the plant collect), leaf area, number of leaves, dry mass of shoot and of roots, foliar nutrient contents and percentage of plants ready for grafting. The highest values for plant height, number of pairs of leaves, stem, and leaf area of rootstocks were obtained with the highest concentration of nutrients. Foliar nutrient content and percentage of plants ready for grafting were considered adequate by using the maximum fertirrigation dose tested(for 5 L: Ca(NO₃) 2.5g, MgSO4 1.75g; KNO3 1.5g; (NH4)(NO3) 1.0g; NH4H2PO4 0.9g; Zn(NO3)2 0.30g; CuSO4 0.20g; EDTA(Fe+2) 0.15g).

Foram testados quatro tipos de soluções nutritivas em delineamento experimental inteiramente casualizado, com 5 repetições. A fertirrigação foi realizada a cada dois dias, utilizando-se 200 mL da solução por recipiente. Avaliou-se altura de planta, diâmetro de caule (5 cm acima do colo da planta), área foliar, número de par de folhas, matéria seca da parte aérea e raízes, teor foliar de nutrientes e porcentagem de plantas aptas à enxertia. Os maiores valores para altura de plantas, número de pares de folhas, diâmetro de caule e área foliar dos porta-enxertos foram obtidos com a concentração mais elevada de nutrientes. O teor foliar de nutrientes e a porcentagem de plantas aptas à enxertia foram considerados adequados com o uso da fertirrigação na maior dose testada (para 5L: Ca(NO₃) 2,5g, MgSO4 1,75g; KNO3 1,5g; (NH4)(NO3) 1,0g; NH4H2PO4 0,9g; Zn(NO3)2 0,30g; CuSO4 0,20g; EDTA(Fe+2) 0,15g).Embrapa Florestas2017-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/134710.4336/2017.pfb.37.89.1347Pesquisa Florestal Brasileira; v. 37 n. 89 (2017): jan./mar.; 73-80Pesquisa Florestal Brasileira; Vol. 37 No. 89 (2017): jan./mar.; 73-801983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1347/559Copyright (c) 2017 Fabio Olivieri de Nobile, Gabriel Fernando Paro, Rogério Farinellihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessOlivieri de Nobile, FabioParo, Gabriel FernandoFarinelli, Rogério2018-01-07T18:59:59Zoai:pfb.cnpf.embrapa.br/pfb:article/1347Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-01-07T18:59:59Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
