Resumo: | Growth of lettuce seedlings in different substrates. This research studied the growth of lettuce seedlings (Lactuca sativa L. cv. Veronica) cultivated under greenhouse conditions, using polystyrene trays with 128 cells and three different commercial substrates: Golden Mix, Plantmax and Plugmix. The statistical design was in the form of randomized blocks, with eight (8) replications. Fifteen days after sowing the seeds, samples (five in total) of plants were taken to evaluate the height, number of leaves, leaf area, leaf specific area, leaf specific weight, absolute and relative growth rates and net assimilation rates. The evaluated growth indexes showed that seedlings produced with the Plantmax and Plugmix substrates could be planted 25 days after sowing, since they had at least four definitive leaves. The Plantmax substrate showed, at the end of the evaluation, the best results in height, dry weight, leaf specific area, absolute growth rates and net assimilation rates. |

A partir do 15º dia após a semeadura iniciaram-se as coletas (num total de cinco) das plantas, para a realização das avaliações de altura, número de folhas, área foliar, área foliar específica, massa específi ca de folha e das taxas de crescimento absoluto e relativo e de assimilação líquida. Os resultados das avaliações dos índices de crescimento indicaram a possibilidade de plantio das mudas produzidas nos substratos Plantmax® e Plugmix® aos 25 dias após semeadura, apresentando no mínimo quatro folhas defi nitivas, apesar do substrato Plantmax® ter garantido ao final das avaliações os melhores resultados em altura, massa seca, área foliar específica e nas taxas de crescimento absoluto e de assimilação líquida.Universidade Federal de Santa Catarina2007-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/20600Biotemas; v. 20 n. 4 (2007); 19-252175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/20600/18789Copyright (c) 2007 Jane Luísa Wadas Lopes, Carmen Sílvia Fernandes Boaro, Milene Rodrigues Peres, Vandeir Francisco Guimarãeshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLopes, Jane Luísa WadasBoaro, Carmen Sílvia FernandesPeres, Milene RodriguesGuimarães, Vandeir Francisco2022-11-21T12:25:14Zoai:periodicos.ufsc.br:article/20600Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T12:25:14Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
