Provedor de dados: 69
Autores: Zhu,Xiaoyang; Li,Xueping; Chen,Weixin; Lu,Wangjin; Mao,Jia; Liu,Tongxin.
Background: C-repeat binding factors (CBFs) are transcription factors that regulate the expression of a number of genes related to abiotic stresses. Few CBF genes have been cloned from other plants but no report in papaya. In present study, a full-length cDNA, designated as CpCBF2, was cloned from papaya using in silico cloning and 5&amp;#8217;- rapid amplification cDNA ends (RACE). Sequence analysis was performed to understand the gene function. The expression pattern of CpCBF2 in papaya under low (7ºC) and high temperature (35ºC) stresses was examined using real-time quantitative polymerase chain reaction (RT-qPCR). Results: The full-length cDNA of CpCBF2 was 986-bp, with a 762-bp open reading frame (ORF) encoding a 254 amino acid polypeptide. CpCBF2...

Oviposition Behavior of Ceratitis capitata Wiedemann (Diptera: Tephritidae): Association Between Oviposition Preference and Larval Performance in Individual Females
Provedor de dados: 82
Autores: JOACHIM-BRAVO,IARA S.; FERNANDES,ODAIR A.; BORTOLI,SÉRGIO A. DE; ZUCOLOTO,FERNANDO S.
The oviposition preference and larval performance of females of Ceratitis capitata (Wiedemann) were examined. Wild or laboratory-reared females were tested for oviposition preference in relation to papaya fruit in different stages of ripeness, as well as to two different fruits: papaya and apple. The results demonstrated that both laboratory-reared and wild females preferred ripe papaya fruit compared to unripe fruit for oviposition, and that ripe papaya was the best for larval performance. When oviposition preference was tested with different fruits (papaya and apple), both wild and laboratory-reared larvae developed better in papaya. However, only wild females showed a preference for oviposition on papaya as opposed to apple. Laboratory-reared females...

Consideraciones sobre la utilización de diferentes densidades en el cultivo de papaya (Carica papaya, L.) "Baixinho de Santa Amalia" en islas canarias
Provedor de dados: 94
Autores: Pastor,Mª Cristina Rodriguez.
El cultivo de papaya en Islas Canarias se ha extendido en los últimos años bajo condiciones de invernadero. La utilización de cultivares de papaya tipo "Baixinho de Santa Amalia" (mutante natural del cultivar "Sunrise") de porte bajo, emisión de la flor a corta altura y precocidad en la floración, resultan de gran interés sobre todo en esta clase de medios. Estas características fenológicas hacen posible el manejo del cultivo a mayores densidades que las empleadas con otros cultivares. Por lo tanto, se ha planteado este trabajo cuyo objetivo principal es determinar cual es el marco de plantación óptimo, que permita obtener mayores rendimientos sin depreciar la calidad del fruto. Para ello, se ha evaluado la producción tanto de las plantas hermafroditas...

Identification and characterization of a resistance gene analog (RGA) from the Caricaceae Dumort family
Provedor de dados: 94
Autores: Amaral,Paulo de Paiva Rosa; Alves,Paulo César Martins; Martins,Natália Florêncio; Silva,Felipe Rodrigues da; Capdeville,Guy de; Souza Júnior,Manoel Teixeira.
The majority of cloned resistance (R) genes characterized so far contain a nucleotide-binding site (NBS) and a leucine-rich repeat (LRR) domain, where highly conserved motifs are found. Resistance genes analogs (RGAs) are genetic markers obtained by a PCR-based strategy using degenerated oligonucleotide primers drawn from these highly conserved "motifs". This strategy has the advantage of the high degree of structural and amino acid sequence conservation that is observed in R genes. The objective of the present study was to search for RGAs in Carica papaya L. and Vasconcellea cauliflora Jacq. A. DC. Out of three combinations of primers tested, only one resulted in amplification. The amplified product was cloned in pCR2.1TOPO and than sequenced using M13...

Autores: Posse,Robson Prucoli; Sousa,Elias Fernandes de; Bernardo,Salassier; Pereira,Messias Gonzaga; Gottardo,Romildo Domingos.
Leaf area estimation is an important feature in physiological research involving predominantly photosynthesis, transpiration and growth. This study was carried out to develop a practical and nondestructive empirical mathematical model to estimate the area of one leaf and the total leaf area for papaya trees (Carica papaya L.). Two irrigated commercial orchards were evaluated over a period of 50 to 550 days after transplanting, during which the length of the leaf midrib (LM) varied from 0.04 to 0.60 m. A mathematical model was developed to estimate the area of one leaf for the papaya tree, taking into account LM and the age of the plant measured in days after transplanting. The model was considered satisfactory. Based on the average length of the last two...

Thermal units or degree day systems can both be used to quantify relationships between plants and air temperature. The Northern Fluminense region holds no tradition for irrigated papaya (Carica papaya L.) cropping and, because of the need for irrigation, it is important knowing its growth and development characteristics under these conditions. This study aimed to determine the relationship between growth rate of papaya plants and degree days, and its effect on crop productivity, under different irrigation levels. An experiment was set up with the cultivar "Improved Sunrise Soil 72/12", in a randomized blocks design, with seven irrigation water depths and three repetitions; crop growth and yield parameters were evaluated. There were significant correlations...

The objective of this study was to determine the effect of CPPU on postharvest quality of ‘Kaek Dum’ papaya fruit. Fruits at the half-ripe stage were selected to test a dipped treatment with 0, 2 and 4 mg/l CPPU for 60 min. Then, all the samples were stored at 12°C (80-85% RH) for 15 days. The results showed that the fruit dipped in 4 mg/L CPPU had lowest firmness and the peel and pulp color development occurred rapidly than those in the other treatments. No differences in weight loss and membrane degradation when indicated by electrolyte leakage were found between treatments. The results indicated that such a CPPU treatment in papaya fruit may be accelerated fruit ripening.

Objetivou-se determinar a viabilidade econômica e o risco do cultivo do mamão na Região Norte do Espírito Santo e comparar os índices econômicos com dados experimentais de irrigação e doses de sulfato de amônio. O experimento foi conduzido na Fazenda Caliman Agrícola S.A., em Linhares, Estado do Espírito Santo. Foram avaliadas, separadamente, duas variedades de mamão, Golden e UENF Caliman 01, em cinco níveis de irrigação (50, 70, 90, 110 e 130% da evapotranspiração de referência), combinados com quatro doses de sulfato de amônio (90, 188, 288 e 377 kg ha-1 mês-1). Na determinação dos riscos e índices da cultura do mamão utilizou-se o cálculo do Valor Presente Líquido, a Taxa Interna de Retorno, a análise de sensibilidade e o método de Monte Carlo. Os...

Autores: Alam, Md. Shafiq; Kaur, Baljinder; Gupta, Kalika; Kumar, Sunil.
Experiments were conducted in completely randomized design in order to assess the shelf-life and quality of minimally processed papaya stored under refrigerated condition (5+10C and 95% RH). Before minimal processing, the semi riped whole papaya was divided into two lots: control (untreated) and mild heat pretreated. The mild heat pretreatment (MHPT) of 450C constant temperature for different exposure time (15, 30 and 45 minutes) was given to whole papaya followed by 24 hrs conditioning in cold room (10C and 95% RH). The minimally processed papaya samples were then dipped in 100 ppm sodium hypochlorite solution for 30 seconds followed by 6hrs dipping in 4.0 % calcium hydroxide solution. Both the untreated and mild heat pretreated samples were packed in...

Classification of papaya crispiness based on mechanical properties
Provedor de dados: 111
Autores: Terdwongworakul, Anupun.
This research investigated an objective technique for the classification of papaya varieties based on crispiness. Five varieties of papaya were sampled with variation in crispiness. The papaya samples were mechanically tested using texture profile analysis and rectangular blade cutting methods. Discriminant analysis based on the mechanical properties measured using rectangular blade cutting was performed to develop a classification model. The obtained discriminant model was capable of classifying the papaya samples into five different groups with an accuracy of 82.4%.

Autores: Fernando,Juliana A.; Melo,Murilo; Soares,Marli K. M.; Appezzato-da-Glória,Beatriz.
Mature zygotic embryos of Carica papaya L. ‘Sunrise Solo’ were used as explants for embryogenesis induction. The explants were inoculated on Murashige and Skoog culture medium supplemented with 2 mg.L-1 2,4-dichlorophenoxyacetic acid and incubated in darkness at 25+2°C. Histological analysis of callogenesis and somatic embryogenesis indicated occurrence of direct and indirect somatic embryogenesis development. Direct somatic embryo formation was observed from hypocotyledonary epidermic cells only from explant 18 days after inoculation. Somatic embryos formed indirectly were originated from embryogenic superficial cells of pre-embryonic complexes located on peripherical and on internal cell layers of callus 49 days after inoculation. Diverse morphological...

The aim of this work was to investigate the potential of castor oil for the control of papaya diseases caused by the fungus Colletotrichum gloeosporioides and the bacterium Pseudomonas caricapapayae. The treatment with 1% castor oil did not significantly affect the fungal growth. The effectiveness of castor oil for the control of anthracnose was shown when 5% and 10% (v/v) were used in the assays resulting in reduced mycelial growth. Fungal sporulation was strongly inhibited at 10% (v/v) concentration of essential oil. The studies with the fresh fruits treated with 5% (v/v) castor oil in aqueous emulsions resulted in effective reduction of pathogen spread in these fruits. No lesion was found in the fruits treated with oil, when compared to the control...

Autores: Cruz,André Freire; Ishii,Takaaki; Matsumoto,Isao; Kadoya,Kazuomi.
An experiment was carried out under greenhouse conditions to observe the distribution of arbuscular mycorrhizal (AM) hyphae in the rhizosphere of papaya and other plants under intercropping system. Special acrylic root boxes with three compartments, separated by nylon mesh screens, were constructed. One outer compartment contained seedlings of papaya (Carica papaya L.) and other contained seedlings of bahiagrass (Paspalum notatum Flügge) or millet (Pennisetum glaucum L. R. Br.). The central compartment was inoculated with an AM fungus (Gigaspora margarita). In another experiment, the outer compartments were treated with 25% MeOH eluates of bahiagrass (BRE) and millet (MRE) root extracts. A control box, containning only papaya seedlings was also prepared....

Banana, papaya and pineapple are the most consumed tropical fruits in the world, being Brazil one of the main producers. Fungi Colletotrichum musae, Colletotrichum gloeosporioides and Fusarium subglutinans f.sp. ananas cause severe post harvest diseases and losses in fruits quality. The aim of this work was to evaluate the effectiveness of five monoterpenes to inhibit the mycelial growth and conidia germination of these three phytopathogens. The monoterpenes citral, citronellal, L-carvone, isopullegol and a-pinene were diluted in ethanol to final concentrations from 0.2 to 1%. All monoterpenes were found to inhibit the growth of the three studies fungi in a dose-dependent manner. Citral was the most effective of the oils tested and showed potent fungicidal...
