Abstract: O camu-camu [Myrciaria dubia (Humb., Bonpl. & Kunth) McVaugh], da família Myrtaceae, é encontrado em áreas inundáveis da Regi o Amaz nica e utilizado como conservante em antioxidantes por seu alto teor de ácido ascórbico. O objetivo deste trabalho foi avaliar porta-enxertos desta família, adaptados a terra firme, visando à propaga o vegetativa de camu-camu. Selecionaram-se duzentas e quarenta mudas de camu-camu, goiabeira (Psidium guajava L.) e pitangueira (Eugenia uniflora L.), que receberam quatro tipos de enxertia, originando doze tratamentos de sessenta plantas, com cinco repeti es. Apenas o porta-enxerto de camu-camu se mostrou compatível. A incompatibilidade entre camu-camu e os porta-enxertos de goiabeira e pitangueira foi demonstrada por análises anat micas.

Abstract:

To achieve high crop yieldin agriculture, the production of plantlets of superior quality is one of thebasic prerequisites. For conilon coffee, the current recommendation in theproduction of clonal plantlets through vegetative propagation is to usediagonal cuttings, in bevel form. However, there are indications that othertypes of cutting have been successfully used to produce plantlets. In thiscontext, this experiment was conducted with the objective of studying thedevelopment of plantlets of conilon coffee obtained by different types ofcuttings. The experiment was conducted in a greenhouse. The cuttings wereobtained from the middle portion of orthotropic stems of standardized plants.The experiment followed a split plot in time design, with three types ofcuttings (bevel, sharp bevel and straight) and two times of evaluation, withfour repetitions. At 30 and 120 days after planting, plantlets were collectedand evaluated. The results show the increase occurred in the variables due tothe straight cut when compared to the others, except for stem diameter.Emphasizing in this context, the straight cut promoted an increase in seedlingheight, production of biomass and in the Dickson’s quality index when comparedto cuttings in bevel and sharp bevel.

Abstract: Observou-se o pegamento de frutos de laranjeira `Pera' enxertada sobre limoeiro `Cravo' em rela o aos quadrantes geográficos (Sudeste, Nordeste, Sudoeste e Noroeste) nos diferentes ter os da copa (basal, mediano e apical) em cinco períodos de coleta. O trabalho foi conduzido em Piracicaba-SP, com localiza o 22o43'S, 43o38'W e 540 metros de altitude. O delineamento experimental foi em blocos ao acaso, considerando-se cada planta um bloco, no esquema fatorial 3x4x5, perfazendo um total de 300 sub-subparcelas. Os parametros avaliados foram o número de flores (1a coleta) e frutos (chumbinhos, nas quatro coletas subsequentes), analisando-se separadamente o 1o período e conjuntamente os demais. Os resultados permitiram observar uma diferen a significativa a nível de 5% tanto para o número de flores em rela o aos quadrantes, destacando-se o SE, como para a intera o alturas x quadrantes, destacando-se o ter o mediano dentro do referido quadrante que diferiu dos demais. N o foi detectada diferen a significativa entre as alturas. Com rela o a percentagem de chumbinhos, foi possível distinguir uma diferen a significativa ao nível de 5% entre as alturas, os quadrantes e períodos, destacando-se o ter o basal e o quadrante SO. A intera o do quadrante dentro da altura e vice-versa, n o apresentou diferen a significativa, embora que no decorrer dos períodos, o comportamento tenha sido semelhante, independente do quadrante ou altura.
