Resumo: In general, polyploidy in plants causes an increase in the size ofvegetative structures. This work aimed to compare diploid plants (2n = 2 x =38) and induced tetraploid plants (2n = 4 x = 76) of Dendrobium nobile Lindl. through the evaluation of themorphological characteristics of flowers, leaves and pseudobulbs. We evaluatedthe parameters height and diameter of pseudobulbs; width and length of leavesand flowers (sepals, petals and labella); and diameter of flowers. The inducedpolyploidization resulted in the increasing the number of internodes (19.9%)and floral pieces, with greater height of the flower (4.5%) and width of thelip (18.5%) decrease in the number of flowers per pseudobulb (40.9%) and thediameter of the pseudobulb (64.9%) and delayed flowering.

Este trabalho objetivou comparar plantas diploides(2n=2x=38) e tetraploides induzidos (2n=4x=76) de Dendrobium nobile Lindl., mediante avaliação das características morfológicas deflores, folhas e pseudobulbos. Foram avaliados a altura e o diâmetro dospseudobulbos e a largura e o comprimento das folhas e flores (comprimento desépalas, de pétalas, de labelo e diâmetro da flor). A poliploidização induzidaem Dendrobium nobile L. resultou no aumento do número de entrenós (19, 9%)e das peças florais, com maior altura da flor (4, 5%) e largura do labelo(18, 5%), na diminuição do número de flores por pseudobulbo (40, 85%) e dodiâmetro do pseudobulbo (64, 9%) e no retardo na floração.Universidade Federal de Viçosa (UFV), Departamento de Fitotecnia (DFT)2019-12-20T18:13:28Z2019-12-20T18:13:28Z2014-10info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVICHIATO, M.
