Resumo: Even whith the advance in the techniques of seedlings production, many problems still remain to be solved, mainly those problems related to seedlings delivery. This work verified the variability of the growth parameters in seedlings of Pinus elliottii in different positions inside the production tray, along the time, seeking to identify the best time and form of delivery of homogeneous and high quality seedlings. In order to achieve these purposes, an experiment was installed in the forest nursery ofSanta MariaFederalUniversity – RS. Ten evaluations of height, diameter of the collar and height/diameter relationship were performed, in intervals of 15 days. It was simulated each tray of the repetition parcel in order to determine the best form of seedlings delivery from the green house. It was verified that, 135 days after  germination, uniformity among  morphologic parameters of seedlings delivery were achieved for the simulations when dividing the tray in Border x Center (BxC), Right x Center x Left (DxCxE), and Quadrants, and that after 180 days, Front x Center x Bottom (FrxCxF) standardization was achieved. Differences in the quality pattern of seedlings collected in different places and submitted to the same development condition were observed and that seedlings delivered on a regular schedule allows obtaining homogeneous quality pattern.

Objetivou-se, neste trabalho, verificar a variabilidade dos parâmetros de crescimento em mudas de Pinus elliottii, em diferentes simulações de posições dentro da bandeja de produção, ao longo do tempo, visando a identificar épocas e formas de expedição de mudas homogêneas e de qualidade. Para tanto, foi instalado um experimento, no viveiro florestal da Universidade Federal de Santa Maria - RS, no qual realizaram-se dez avaliações da altura, diâmetro do coleto e relação altura/diâmetro, em intervalos de 15 dias. Simulou-se cada bandeja de produção em parcelas para se determinar a melhor forma de saída das mudas da casa de vegetação. Verificou-se que, aos 135 dias após a germinação, já havia uniformidade entre seus parâmetros morfológicos, para as simulações de retirada de mudas, dividindo-se a bandeja em Bordadura x Centro (BxC), Direita x Centro x Esquerda (DxCxE), e quadrantes, e que, aos 180 dias, houve uniformização para Frente x Centro x Fundo (FrxCxF). Observou-se que houve diferenças quanto ao padrão de qualidade desejado quando as mudas são coletadas de diferentes locais, submetidas a mesma condição de desenvolvimento, e que a retirada das mudas, de maneira escalonada, permite obter mudas com o mesmo padrão de qualidade.Universidade Federal de Lavras (UFLA)2015-09-112017-08-01T20:16:06Z2017-08-01T20:16:06Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfREIS, E.
