Resumo: The objective of this work was to evaluate the effect of sorbitol and on the growth period on minimum growth and subsequent resumed growth of Luehea divaricata shoots. Two tests were performed, one of minimal growth and the other of resumed growth. In the presence of sorbitol at minimum growth there was a reduction in averages of survival, establishment, number of leaves and primary and secondary roots. When the period was considered, it was observed a reduction at 30 days followed by increase and stabilization in averages of primary and secondary roots, and number of leaves and of shoots. The presence of sorbitol promoted a significant reduction in averages, in the resumed growth, for survival, establishment, number of leaves and of shoots. A decrease of averages in survival and establishment was observed only after 120 days. The presence of sorbitol is important for in vitro conservation of L. divaricata by minimum growth, which can be carried out for up to 120 days. The subsequent resumed growth of the shoots preserved in the presence of sorbitol is limited to 90 days.

Foram realizados dois ensaios, um de crescimento mínimo e o outro de retomada de crescimento. No crescimento mínimo, observou-se redução nas médias de sobrevivência, estabelecimento, número de folhas e de raízes primárias e secundárias na presença de sorbitol. Quando se considerou o período, observou-se redução aos 30 dias seguida de aumento e estabilização nas médias de raízes primárias e secundárias e do número de folhas e de brotos. Na retomada de crescimento, a presença de sorbitol promoveu uma redução significativa nas médias de sobrevivência, estabelecimento, número de folhas e de brotos. Somente a partir dos 120 dias observou-se um decréscimo das médias na sobrevivência e estabelecimento. A presença de sorbitol é importante para realizar a conservação in vitro de L. divaricata via crescimento mínimo, o qual pode ser realizado por um período de até 120 dias. A subsequente retomada de crescimento das brotações conservadas na presença de sorbitol é limitada a 90 dias.Embrapa Florestas2021-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/202610.4336/2021.pfb.41e201902026Pesquisa Florestal Brasileira; v. 41 (2021)Pesquisa Florestal Brasileira; Vol. 41 (2021)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2026/1646Copyright (c) 2021 Karol Buuron da Silva, Lia Rejane Silveira Reiniger, Silvia Machado dos Santos Rabaiolli, Caetano Miguel Lemos Serrote, Charlene Moro Stefanelhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Karol Buuron daReiniger, Lia Rejane SilveiraRabaiolli, Silvia Machado dos SantosSerrote, Caetano Miguel LemosStefanel, Charlene Moro2021-11-18T11:01:58Zoai:pfb.cnpf.embrapa.br/pfb:article/2026Revistahttps://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:2021-11-18T11:01:58Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
