Alternaria brown spot (ABS) is the main fungal disease of mandarins. Cause damage to fruits, branches and leaves. For determinations severity in fruit, there a specific diagrammatic scale, which does not occur for foliar lesions. In order standardize leaf reviews ABS citrus, scale was developed from collection symptomatic Dancy tangerine Murcott tangor leaves, with ten levels, zero 97% area damaged by pathogen. They were tested five evaluators who analyzed 100 pictures leaves without use...

Desde 1997, o Centro APTA Citros Sylvio Moreira/IAC conduz um amplo programa de melhoramento genético citros via cruzamentos dirigidos. Destes cruzamentos, alguns híbridos tangerina com laranja vêm sendo selecionados para qualidade fruta e potenciais novas variedades. Com isso, frutos híbrido entre tangor Murcott (TM) Pera (LP), denominado TMxLP 290, foram submetidos a análises físico-químicas teste sensorial aceitabilidade, fim avaliar aceitação tal variedade pelo mercado consumidor. Foram...

ABSTRACT Planting new types of tangerines is an interesting alternative for Brazilian citrus growers due to the increasing domestic market. Thus, aim this study was evaluate a less exploited variety tangerine, Fremont. The physics and chemical quality fruit juice (mass, peel color, yield, acidity, soluble solids maturation index) evaluated, followed by sensory testing ranking difference preference Nules clementine Ponkan tangerine varieties. Fremont produces fruits that meet standards...

Alternaria brown spot (ABS), caused by alternata f. sp. citri, is the main fungal disease plaguing tangerines. The symptoms are falling leaf and fruit, resulting in loss of production quality. initial leaves characterized small or black spots, surrounded, not, yellowish halos. In dark cortical patches appear that can easily break. this study, winter pruning plants was investigated to complementary control ABS. experiment conducted 10-year-old Honey Murcott tangor plants, where two treatments...

The cultivation of new types oranges can be a good alternative for citrus growers because there is growing domestic market and export prospects. Due to these expectations, it essential search cultivars use in the fresh fruit industry. Therefore, aim this work was physicochemically characterize fruits ‘Navel’ oranges, seeking alternatives with characteristics, such as earliness, lack seeds, color organoleptic characteristics desired by consumer market. five orange were evaluated, namely,...

Abstract The planting of new types table citrus is an interesting alternative for growers in the state Paraná, as this domestic market continues to grow and needs innovation. Thus, aim study was evaluate acceptance storage a hybrid region Londrina / PR, Fremont IAC 543 mandarin (Citrus clementina hort. ex Tan x C. reticulataBlanco). Treatments were: fruits with without wax coating at room temperature [21 ± 2 °C relative humidity (RH) = 60 5%] up 36 days. Sensory (acceptance test purchase...

Strelitzias are tropical plants that have shown great interest in the market and can be used landscaping floral arrangements. Aiming to extend its postharvest life, objective of work was evaluate different concentrations commercial product based on carnauba wax longevity Strelitzia juncea reginae leaves. The experiment conducted a completely randomized design with five treatments six repetitions, one leaf per repetition for each species. were: 0% (control), 2%, 20%, 40% 100%. loss mass (%)...

Abstract The pomegranate fruit exhibits medicinal properties due to the nutraceutical characteristics, especially of its peel. objective this study was analyze influence different drying methods on physicochemical and biochemical characteristics experiment conducted in a completely randomized design subdivided plots: 4 (full sun [SUN], chamber [DC] at 60 ± 2 °C, cold 10 °C 60% relative humidity (RH) [CC], solar dryer [SD]) × (presence or absence 1% ascorbic acid [AA]). analyzed variables...

Brazil it's the second country with higher diversity of PASSIFLORACEAE. The genus Passiflora L. is richest one over 500 species mainly distributed in tropical America. most consumed, studied, cultivated and commercialized P. edulis, which commonly found two forms, purple yellow passion fruits. fruit world popular juice principal product made from it. Due to high importance consumers opinion for any horticultural product, we perform an experiment regular evaluate acceptances preference fruits...

Abstract Soil cover with plastic film is a practice used to optimize the agronomic performance of different crops, but its behavior in citrus growing conditions Brazil remains unknown. Five experiments commercial orchards located state São Paulo, rainfed or irrigated systems, were carried out evaluate effect soil (white/black silver/black color) on vegetative growth and initial production sweet orange trees up 3.5 years after planting. In each location experiment, completely randomized...

The yellow passion fruit (Passiflora edulis f. flavicarpa) needs pollinators for fructification due to the existence of mechanisms that impede self-pollinating. Pollinators great efficiency in Brazil are bumblebee species (Xylocopa frontalis, X. grisescens and Suspecta). Deforestation by agricultural expansion region has a negative impact on these pollinators’ populations, leaving space action cleptobiotic with further damage production. objective this study was evaluate frequency...
