Influência da vassoura de bruxa na fenologia do Cupuaçuzeiro

The principal limiting factor is witch's broom disease, caused by Crinipellis perniciosa (Stahel) Singer, the only economic control for which is phytosanitary pruning. The phenology of 10 cupuassu plants grown in a fertilized monoculture on a nutrient poor Oxisol near Manaus, Amazonas, Brazil, was studied from May 1987 to December 1990. The number of flowers was reduced by the witch's broom and the pruning, but the duration and periodicity of flowering were not much affected. The mean number of fruits per tree fell from 36 in 1987 to 6 in 1989 as a result of the disease and its control, but recovered to 15 in 1990. Fruiting was slightly earlier and its duration was shorter than in a previous study, possibly due to the fertilization or the genotype studied. Fruit set fell from 1.4% in 1987 to 0.5% in 1989 and recovered to 1.8% in 1990, suggesting recovery of the plants. Leaf and shoot flushing and leaf fall increased markedly as a result of the disease in late 1987 and 1988 and were markedly reduced by pruning in 1989-90.

Schum.] está em franca expansão na Amazônia brasileira. O principal fator limitante é a vassoura de bruxa, doença causada pela Crinipellis perniciosa (Stahel) Singer, cujo único controle econômico conhecido é a poda fitossanitária. A fenologia de dez cupuaçuzeiros em monocultivo, em solo Latossolo Amarelo distrófico adubado na região de Manaus, AM, foi avaliada de maio 1987 a dezembro 1990. O número de flores foi reduzido pela vassoura e pela poda, mas a duração e periodicidade da floração não foram muito afetadas. O número médio de frutos por planta caiu de 36 em 1987 para 6 em 1989, afetado pela vassoura e pela poda, tendo recuperado para 15 em 1990. A frutificação foi antecipada e sua duração reduzida em comparação ao estudo anterior, possivelmente devido à adubação e/ou ao genótipo estudado. O vingamento caiu de 1,4% em 1987 para 0,5% em 1989 e aumentou para 1,8% em 1990, sugerindo a recuperação das plantas. A brotação foliar e queda das folhas aumentaram marcadamente como resultado da influência da vassoura de bruxa em 1988 e foram reduzidas pela poda no período de 1989-90. Os fenofases não foram muito afetados pela vassoura de bruxa embora o número de flores e frutos tenham sido. 2020-04-24T15:33:01Z 2020-04-24T15:33:01Z 1999 Artigo https://repositorio.inpa.gov.br/handle/1/13601 10.1590/1809-43921999291019 pt_BR Volume 29, Número 1, Pags. 13-13 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica |
