Resumo: | The objective of this work was to evaluate the phytotoxicity of a plant vitrification solution (PVS2), and the survival of shoot tips of the sugarcane variety SP716949, after cryopreservation by droplet-vitrification. Shoot tips were precultured for 24 hours in MS medium containing 0.3 mol L-1 sucrose, and exposed to PVS2 for 0, 20 or 30 min. Shoot tips were then immersed in liquid nitrogen. Thawing was fast in concentrated sucrose solution (1.2 mol L-1). PVS2 is a nontoxic to shoot tips, which in turn are sensitive to liquid nitrogen. The best results occurred when shoot tips were maintained for up to 20 min in PVS2 solution, before freezing, with 20% survival. |

Ápices caulinares foram pré-cultivados por 24 horas em meio MS com sacarose a 0,3 mol L-1 e expostos por 0, 20 ou 30 min a PVS2. Em seguida, os ápices foram mergulhados em nitrogênio líquido. O descongelamento em solução concentrada de sacarose (1,2 mol L-1) foi rápido. A PVS2 não tem efeito tóxico aos ápices que, no entanto, são sensíveis ao nitrogênio líquido. O melhor resultado ocorreu, quando os ápices foram mantidos por 20 min na solução PVS2, antes do congelamento, com 20% de sobrevivência.Empresa Brasileira de Pesquisa Agropecuária (Embrapa), Secretaria de Pesquisa e Desenvolvimento (SPD)2019-12-20T18:02:17Z2019-12-20T18:02:17Z2013-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfNOGUEIRA, G.
