Resumo: The study aimed to evaluate the influence of storage length on Tectona grandis mini-cuttings survival and rooting. A factorial arrangement (4 x 7) was utilized, based on four clones (Carapá, Ipê, GU5 and TB7) and seven time intervals from mini-cuttings harvesting until final sowing (0, 1, 2, 4, 8, 12 and 16 hours). A randomized block design with three replicates and 16 mini-cuttings per experimental unit was utilized. Survival and rooting rates were evaluated after greenhouse culture (30 days after sowing) and after shadow house culture (40 days after sowing); as well as height, collar diameter, aerial and root biomass 55 days after sowing. No significant differences were observed in survival and rooting rates among time intervals in teak mini-cuttings preparation from these four clones. However differences among clones were registered for rooting rate, suggesting a genotypic effect. Survival and rooting rates were very high after greenhouse culture (93% and 90% respectively), as well as survival after culture in a shadow-house (88%).

O delineamento experimental foi em arranjo fatorial (4 x 7), considerando quatro clones (Carapá, Ipê, GU5 e TB7) que são parte do programa de melhoramento genético da empresa Agrícola VerdeNovo, selecionados em Mato Grosso, Brasil. Com sete períodos de tempo (tratamentos) entre a coleta/preparado e o estaqueamento das miniestacas (0, 1, 2, 4, 8, 12 e 16 horas), em delineamento estatístico de blocos ao ocaso, com três repetições e parcelas de 16 miniestacas. Avaliaram-se a sobrevivência e o enraizamento de miniestacas na saída da casa de vegetação (30 dias após estaqueamento) e da casa de sombra (40 dias após estaqueamento), o crescimento em altura e diâmetro do colo, a biomassa da parte aérea e do sistema radicular aos 55 dias após estaqueamento. Os resultados evidenciam que não há influência significativa do intervalo de tempo, entre coleta/preparo e estaqueamento de miniestacas de teca, na sobrevivência e no enraizamento dos quatro clones estudados. Foi constatada a existência de efeito genotípico no enraizamento dos quatro clones avaliados, os quais obtiveram altas percentagens de sobrevivência e de enraizamento na saída da casa de vegetação (93% e 90% respetivamente), assim como sobrevivência na saída da casa de sombra (88,%).Revista Árvore2018-01-10T14:52:17Z2018-01-10T14:52:17Z2017-08-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1806-9088http://dx.doi.org/10.1590/1806-90882017000300003http://www.locus.ufv.br/handle/123456789/16276engv. 41, n. 3, e410303, Ago. 2017Badilla, YorlenyXavier, AloisioGamboa, Olman Murilloinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:04:15Zoai:locus.ufv.br:123456789/16276Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:04:15LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
