Stenzel, Neusa Maria Colauto;Neves, Carmen Silvia Vieira Janeiro;
Scientia Agricola , 2004, DOI: 10.1590/S0103-90162004000200005
Abstract: the 'tahiti' lime (citrus latifolia tanaka) is an important commercial citrus cultivar in brazil. 'rangpur' lime has being used as its main rootstock, but it is susceptible to root rot caused by phytophthora, reducing tree longevity. an experiment was set up in a randomized block design, with three trees per plot of each rootstock and four replicates, and run for 12 years, aiming to compare the performance of 'iac-5 tahiti' lime, budded on 'rangpur' lime (citrus limonia osb.); 'c-13' citrange (citrus sinensis (l.) osb. × poncirus trifoliata (l.) raf.); 'african' rough lemon (citrus jambhiri lush.); 'volkamer' lemon (citrus volkameriana ten. & pasq.); trifoliate orange (poncirus trifoliata (l.) raf.); 'sunki' mandarin (citrus sunki hort. ex tan.) and 'cleopatra' mandarin (citrus reshni hort. ex tan.). eleven years after the establishment of the orchard, trees with the greatest canopy development were budded on 'c-13' citrange and 'african' rough lemon, and both differed significantly from trees budded on trifoliate orange, 'sunki' and 'cleopatra' mandarins, which presented the smallest canopy development. trees budded on 'rangpur' lime and 'c-13' citrange had the highest cumulative yields, and were different from trees budded on trifoliate orange, 'cleopatra' and 'sunki' mandarins. there was no rootstock effect on mean fruit weight and on the total soluble solid/acid ratio in the juice. the 'rangpur' lime and the 'cleopatra' mandarin rootstocks reduced longevity of plants.

Raf.); 'Sunki' mandarin (Citrus sunki Hort. ex Tan.) and 'Cleopatra' mandarin (Citrus reshni Hort. ex Tan.). Eleven years after the establishment of the orchard, trees with the greatest canopy development were budded on 'C-13' citrange and 'African' rough lemon, and both differed significantly from trees budded on trifoliate orange, 'Sunki' and 'Cleopatra' mandarins, which presented the smallest canopy development. Trees budded on 'Rangpur' lime and 'C-13' citrange had the highest cumulative yields, and were different from trees budded on trifoliate orange, 'Cleopatra' and 'Sunki' mandarins. There was no rootstock effect on mean fruit weight and on the total soluble solid/acid ratio in the juice. The 'Rangpur' lime and the 'Cleopatra' mandarin rootstocks reduced longevity of plants.

Abstract: As anonáceas cultivadas comercialmente têm sido propagadas através de enxertia, sendo o porta-enxerto obtido por sementes. Entretanto, as sementes dessas plantas apresentam substancias inibidoras de germina o que, juntamente com um tegumento resistente e impermeável, dificultam a germina o. Este trabalho teve como objetivo avaliar a germina o de sementes de fruta-do-conde (Annona squamosa L.) e dos cultivares de atemóia 'PR-1', 'PR-3' e 'Gefner' (Annona cherimola Mill. X Annona squamosa L.), que foram escarificadas com lixa e submetidas aos seguintes tratamentos por 24 horas: ácido giberélico (GA3) a 50 ppm; GA3 a 100 ppm; água a 5oC; água a 30oC. A testemunha n o recebeu nenhum tipo de tratamento. As sementes das cultivares de atemóia tratadas a 50 e 100 ppm de GA3 n o apresentaram diferen a entre si, proporcionando 55 a 67 % de germina o para 'Gefner' e 'PR-3', significativamente superiores aos demais tratamentos, que tiveram de 1 a 21 %. Para 'PR-1' esta diferen a também foi verificada, com germina o de 35 a 36 % para os tratamentos com GA3 e 1,25 a 2,5 % para os demais. O tratamento de 50 ppm de GA3 foi significativamente superior aos demais tratamentos para a fruta-do-conde, com 75 % de germina o, enquanto que em 100 ppm de GA3 apresentou 44 % e os demais tiveram de 2,5 a 3,7 %. O índice de velocidade de germina o foi significativamente maior para sementes tratadas com GA3 a 50 e 100 ppm.

Abstract: Oncidium varicosum is a native Brazilian orchid popularly known as ‘Golden Shower′ because of its very ramified inflorescence and many yellow flowers. The carboydrate type and concentration are important in promoting plantlet development of in vitro orchids. The present study was carried out to asses the effect of different carbohydrate sources and concentrations on the in vitro growth of O. varicosum plantlets. Murashige e Skoog culture medium was used modified with half concentration of the macronutrients. The plantlets, derived from seeds that were already established in vitro and 0.8 + 0.2 cm in height, were inoculated in the culture media containing the following carbohydrate sources: saccharine, maltose and glucose, at concentrations of 0, 10, 20, 30, 60 and 90 g.L-1. The following variables were analyzed 8 months later: canopy height, number of roots, greatest root length, pseudobulb diameter and fresh weight. A completely randomized block experimental design was used with five replications per treatment. Analysis of variance and the Tukey test (5%) were performed to compare the means. It was concluded that 60 g.L-1 saccharose was the best treatment for all the parameters assessed. The sugars 30 g.L-1 glucose and 60 g.L-1 maltose were also suitable, but presented lower pseudobulb diameter and lower fresh weight when compared to 60 g.L-1saccharose. O trabalho teve o objetivo de avaliar a influência do ácido indol-butírico sobre o enraizamento de estacas de acerola (Malpighia emarginata D. C.) na Universidade Estadual de Londrina. As plantas matrizes utilizadas pertencem a sele o Camb-6 do IAPAR, tiveram suas estacas colhidas com 10 a 12 cm de comprimento, com três a quatro pares de folhas e foram submetidas a uma imers o rápida (10 segundos) em solu es de ácido indol-butírico (AIB) com cinco concentra es (0, 500, 1.000, 1.500, 2.000 mg L-1). O delineamento estatístico adotado foi o de blocos ao acaso com cinco repeti es, sendo cada parcela composta por 10 estacas. O ácido indol-butírico n o influenciou o enraizamento das estacas, que apresentaram 36 a 46% de enraizamento.

Abstract: The aim was to study the distribution of the root system of Rangpur lime (Citrus limonia Osbeck), Rough lemon (Citrus jambluri Lush.), Cleopatra mandarin (Citrus reshni Hort ex Tan.) and Trifoliata (Poncirus trifoliata (L.) Ralf.), under ‘Folha Murcha’ orange plant scion in subtropical climate, using the auger method. The samples were taken parallel to the line of planting (row) 0.5; 1.0; 1.5 and 2.0 m away from the trunk and perpendicular to the line of planting (inter-row) 0.5; 1.0; 1.5; 2.0; 2.5; 3.0 and 3.5 m away from the trunk. These samples were stratified into 0 – 0.1; 0.1 – 0.2; 0.2 – 0.4; 0.4 – 0.6 m deep. Dry mass, effective depth and effective distance of the root system of plants were determined. Randomized blocks design was used with four treatments and four replications, with one plant for each plot. Cleopatra mandarin plants had the highest total mass of roots 2.0; 2.5 and 3.0 m away from the trunck in inter-row, and in superficial layers of the following sampling sites: 0.5 and 1.0 m away from the trunk towards row and 1.5 e 2.0 m away from the trunck towards inter-row. Rough lemon plants showed greater effective depth of the roots in the rows than the other rootstocks. Objetivou-se estudar a distribui o do sistema radicular dos limoeiros ‘Cravo’ (Citrus limonia Osbeck) e ‘Rugoso da áfrica’ (Citrus jambluri Lush.), tangerineira ‘Cleópatra’ (Citrus reshni Hort ex Tan.) e ‘Trifoliata’ (Poncirus trifoliata (L.) Ralf.), sob a laranjeira ‘Folha Murcha’ em clima subtropical. As amostragens foram realizadas, pelo método do trado, paralelamente à linha de plantio (entre plantas) a 0,5; 1,0; 1,5 e 2,0 m de distancia do tronco e perpendicularmente à linha de plantio (entrelinhas) a 0,5; 1,0; 1,5; 2,0; 2,5; 3,0 e 3,5 m de distancia do tronco. Essas amostras foram estratificadas em 0 – 0,1; 0,1 – 0,2; 0,2 – 0,4; 0,4 – 0,6 m de profundidade. Foram determinadas: massa seca, profundidade e distancias efetivas do sistema radicular das plantas. O delineamento experimental utilizado foi o de blocos ao acaso, com quatro tratamentos e quatro repeti es, com uma planta por parcela. A tangerineira ‘Cleópatra’ apresentou maior massa total de raízes a 2,0, 2,5 e 3,0 m de distancia do tronco na entrelinha e nas camadas superficiais dos seguintes locais de amostragem: 0,5 e 1,0 m de distancia do tronco no sentido da linha e 1,5 e 2,0 m de distancia do tronco no sentido da entrelinha. O limoeiro ‘Rugoso da áfrica’ apresentou maior profundidade efetiva das raízes na linha de plantio.

Abstract: This research work had as objective to evaluate and to compare the amount and the distribution of the roots of 4.5 years old West Indian Cherry plants, in a clayey Typic Hapludox, propagated by: a) seeds (and subsequent grafting); b) cuttings. It was used the trench profile method, in the planting rows and in the inter-rows, covering half spacing. Images of 25 x 25 cm were taken in the trenches and evaluated with the SIARCS program. The density of fine ( 0.5 cm of diameter) were assessed. There was no difference between the two propagation systems for the density of fine roots in the planting row. The plants propagated by cuttings presented larger density of fine roots in the depth 0-0.25 m; and plants propagated by seeds showed more roots in the depths 0.25-0.50 and 0.50-0.75 m in the inter-row. The plants propagated by seeds presented larger density of thick roots than plants propagated by cuttings in the layers 0-0.25 and 0.25-0.50 m in the row and in the general density of roots (row + inter-row). O trabalho teve o objetivo de avaliar e comparar a quantidade e a distribui o das raízes de plantas de aceroleira (Malpighia emarginata) com 4,5 anos de idade, em Latossolo Vermelho distroférrico, propagadas por: a) semeadura, e posterior enxertia; b) estaquia. Para a avalia o das raízes utilizou-se o método da trincheira, aberta em duas dire es: na linha e na entrelinha, até metade do espa amento entre plantas. Nas trincheiras foram tomadas imagens de 25 x 25 cm e avaliadas com o programa SIARCS. Foi avaliada a densidade de raízes finas (< 0,5 cm de diametro) e de raízes grossas (> 0,5 cm de diametro) por área de trincheira. N o houve diferen a entre os dois sistemas de propaga o, na linha de plantio, para a densidade de raízes finas. Na entrelinha, as plantas propagadas por estaca apresentaram maior densidade de raízes finas na profundidade 0-0,25 m, enquanto que nas propagadas por semente apresentaram mais raízes finas nas profundidades 0,25-0,50 e 0,50-0,75 m. Para as raízes grossas, as plantas propagadas por semente apresentaram maior densidade que o tratamento estaca na linha de plantio para as profundidades 0,00-0,25 e 0,25-0,50 m e na média geral da densidade de raízes (linha + entrelinha).
