No full textO objetivo do trabalho foi determinar as variaçÔes do conteĂșdo de glucose, frutose e sorbitol em gemas e ramos de dois anos de macieira que receberam ou nĂŁo frio suplementar durante o perĂodo de dormĂȘncia. Os ramos da cultivar Imperial Gala foram coletados em Porto Amazonas-PR, regiĂŁo de baixa ocorrĂȘncia de frio, em intervalos de 21 dias, de abril a agosto, e receberam ou nĂŁo tratamento com frio suplementar de 1.440 horas, Ă temperatura de 4 a 7°C. As anĂĄlises dos monossacarĂdeos foram realizadas em gemas e porçÔes de ramos adjacentes a elas por cromatografia lĂquida de alta eficiĂȘncia (HPLC). Houve acĂșmulo de glucose e frutose em gemas de macieira de abril a agosto, e este aumento foi estimulado pelo tratamento com 1.440 horas de frio. O conteĂșdo de glucose e frutose nos ramos adjacentes Ă s gemas elevou-se de abril ao inĂcio de agosto, com posterior queda no final de agosto e o tratamento com frio antecipou esta dinĂąmica. O conteĂșdo de sorbitol em gemas e ramos de macieira oscilou de abril a agosto, e sua dinĂąmica foi alterada pelo frio.<br>The objective of this work was to evaluate the variation of glucose, fructose and sorbitol content in two year old buds and stems of apple trees during the dormancy period. Stems of cv. Imperial Gala were collected in Porto Amazonas, Parana State, Brazil, a region of low chill occurence, at intervals of 21 days from April to August and were treated or not with 1,440 hours of chill (4 to 7°C). The monosaccharides were analysed in buds and stem tissues close to buds by high performance liquid chromatography (HPLC). There was an increase of glucose and fructose content in buds from April to August and it was stimulated by the chill treatment. The glucose and fructose content in stems increased from April to August 2nd followed by a reduction in August 23rd and the chill treatment advanced this dynamics. The sorbitol content in buds and stems of apple tree oscillated from April to August and its dynamics was modified by the chill treatment
