Resumo: The present work aimed to evaluate the growth of shoots of a rootstock of the plant growth of the apple (Malus prunifolia Borkh, cv. Marubakaido) tree during the acclimatization process. After two weeks of acclimatization, the plantlets were transferred to a growth room and kept under temperature of 4±1ºC, 16-hour photoperiod at 5 µE m-2 s-1 of radiation for 0, 240, 480, 720, 960, 1,200 and 1,440 hours. So, the plantlets were transferred to the greenhouse where their growth was evaluated every two weeks during 90 days. Internode length, bud number and dry matter weight of aerial part and roots were also evaluated at the end of the experiment. The percentage of plant survival was evaluated after a month in greenhouse. An increase was verified in the plant height and internode length proportional to the time kept under low temperature. Chill did not affect the plant survival, the bud number and the dry weight of aerial part, but it did affect the root dry weight.

Marubakaido, durante o processo de aclimatização. Durante as duas primeiras semanas de aclimatização, as plântulas foram transferidas para uma câmara de crescimento, e submetidas à temperatura de 4±1ºC por 0, 240, 480, 720, 960, 1.200 e 1.440 horas, sob fotoperíodo de 16 horas e radiação de 5 µE m-2 s-1. Em seguida, foram conduzidas para casa de vegetação e avaliadas por um período de 90 dias. Ao final do experimento, avaliou-se, ainda, o comprimento dos entrenós, o número de gemas e o peso da matéria seca da parte aérea e das raízes das plantas. A porcentagem de sobrevivência também foi avaliada após um mês de permanência das plantas em casa de vegetação. Houve aumento na altura das plantas e no comprimento dos entrenós, proporcional ao tempo de sua permanência sob baixa temperatura. O frio provocou decréscimo no peso seco das raízes, porém não afetou a sobrevivência das plantas, o número de gemas e o peso da matéria seca da parte aérea.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPereira, Jonny Everson ScherwinskiFortes, Gerson Renan de LucesSilva, João Baptista da2001-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6118Pesquisa Agropecuaria Brasileira; v.36, n.1, jan. 2001; 89-95Pesquisa Agropecuária Brasileira; v.36, n.1, jan. 2001; 89-951678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6118/3185info:eu-repo/semantics/openAccess2014-09-16T17:58:35Zoai:ojs.seer.sct.embrapa.br:article/6118Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-16T17:58:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
