The Citrus Peel Miner, Marmara salictella, in Arizona Grapefruit in 1994Gibson, Roberta, Bacon, Dean, Langston, Dave, Kerns, David, Gibson, Richard 11 1900 (has links)
The life history of the citrus peel miner was investigated. The peel miner larvae were found in low levels in grapefruit throughout the summer. In September the infestation level rose to 10%. Peel miners were also found in oleanders, mesquites, grapes and tree cottons. Peel miners were found to infest at higher levels in the skirt of the tree (less than 32. A parasitic wasp of the larval stage was discovered

Heat Unit Based Crop Coefficient for Grapefruits TreesHla, A. K., Martin, E. C., Waller, P., Slack, D. C. 09 1900 (has links)
Using portable sap flow sensors, the onset and volume of sap moving up the branches of grapefruit (Citrus Paradisi Macfadyen) trees was monitored on an hourly basis. Reference evapotranspiration (ETo) data was obtained from The Arizona Meteorological Network (AZMET). Crop evapotranspiration (ETc) was estimated from soil moisture measurements using a neutron probe. The threshold temperature limits were delineated from an evaluation of the hourly sap flow responses to cold winter and extreme summer temperatures. The heat based crop curve was derived from a correlation of the crop coefficients with heat unit over one crop year. The heat based crop coefficients were found to be similar to crop coefficients derived by other researchers.

No. of bitstreams: 0 / O Brasil é um grande produtor de frutas, mas com seu clima tropical (elevada umidade e temperatura) acaba proporcionando condições desfavoráveis à conservação de alimentos e principalmente das frutas. A radiação ionizante tem potencial para resolver problemas que afetam o suprimento de alimento em muitos países. Utilizando a dose certa, esta tecnologia tem a capacidade de estender o tempo de prateleira, segurança fitossanitária e controlar a maturação em frutas frescas. Existem no mundo variedades de uva onde a maioria delas pertence à espécie Vitis vinifera. Desta fruta é possível a obtenção de passas como forma de manter as características do produto natural e dificultar a proliferação de microrganismos que possam promover sua deterioração. As maiores fontes de compostos fenólicos são encontradas nas uvas quando comparado a outras frutas e vegetais e, um destes compostos é o resveratrol que se destaca no tratamento de diversas enfermidades, tais como: cardiovasculares, cancerígenas e doenças neurológicas. As amostras de uva foram irradiadas no Multipropósito de 60Co, instalado no Centro de Tecnologia das Radiações (CTR-IPENCNEN/ SP) nas doses de: controle; 0,5; 1; 1,5 e 2 kGy para as analises de cor, textura, sensorial, microbiológico e vida de prateleira. Para as análises de fenólicos totais e resveratrol utilizou-se as doses: controle; 1,5 e 3 kGy. Não ocorreu crescimento bacteriano em nenhuma das amostras. As doses de: 0,5 e 1,5 kGy da variedade de uva Benitaka tiveram boa aceitação no teste sensorial e vida de prateleira, sendo que, as uvas passas não apresentaram variações nestas analises. Foi verificado a presença de resveratrol em todas as amostras tratadas com a radiação ionizante. / Dissertacao (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Citrusinių vaisių, skirtinguose prekybos centruose, kokybiniai rodikliai / Qualitative index of citrus fruits in different supermarketsGrigaliūnienė, Gintarė 18 June 2013 (has links)
Darbo tikslas: Citrusinių vaisių, skirtinguose prekybos centruose, kokybinių rodiklių palyginimas.
Darbo uždaviniai: Išanalizuoti ir apibendrinti mokslinę literatūrą apie citrusinių vaisių kokybinių rodiklių kitimą laikymo metu. Susipažinti su citrusinių vaisių ėminių ėmimo metodika. Nustatyti citrusinių vaisių kokybinius rodiklius. Apibendrinti tyrimų rezultatus ir pateikti išvadas.
Išvados: Tyrimo metu didžiausiomis citrinomis 151,8 g buvo prekiauta Maxima prekybos centruose, kurių kilmės šalis buvo Graikija. Didžiausiu sultingumu 44,9 proc. pasižymėjo Iki prekybos centruose parduodamos citrinos, kurios buvo mažiausios 94,9 g. Didžiausiais apelsinais 404,5 g buvo prekiauta Maxima prekybos centruose, tuo tarpu sultingumas didžiausias nustatytas 45,9 proc. Iki prekybos centruose parduodamais apelsinais, kurių kilmės šalis buvo Ispanija. Mandarinai didžiausi buvo parduodami Maxima prekybos centruose, kurių svoris buvo 62,0 g, kilmės šalis Italija. Sultingiausiais mandarinais buvo prekiaujama Iki prekybos centruose, jų sulčių kiekis nustatytas 52,4 proc. kilmės šalis Ispanija. Tyrimo metu didžiausi greipfrutai buvo parduodami Maxima prekybos centruose, jų svoris 493,0 g, tačiau sultingiausi buvo parduodami Prisma prekybos centruose, jų sulčių kiekis nustatytas 44,6 proc. kilmės šalis Graikija.
Bendra išvada: Tyrimų metu nustatyta, kad citrusiniai vaisiai (apelsinai, citrinos, mandarinai), kurių kilmės šalis buvo Ispanija, pasižymėjo didžiausiu sultingumu, tačiau jie buvo... [toliau žr. visą tekstą] / The aim: The comparison of qualitative index of citrus fruits in different supermarkets.
The goals of the work: To analyze and summarize scientific literature about changes of qualitative index of citrus fruits during their storage; to have a look at techniques of taking samples from citrus fruits; to determine qualitative indexes of citrus fruits; to generalize the results of the research and to make the conclusions.
Conclusions: The biggest lemons that were being sold at “Maxima” supermarkets during the research weighted 151.8 g, they were from Greece. The juiciest (44.9%) lemons were being sold at “Iki” supermarkets, but they were also the smallest ones (94.9 g). The biggest oranges were found at “Maxima” supermarkets (404.5 g); whereas the juiciest ones (45.9%) were from Spain and they were being sold at “Iki” supermarkets. The biggest tangerines that were being sold at “Iki” supermarkets weighted 62.0 g, they were from Italy. The juiciest (52.4%) tangerines observed were being sold at “Iki” supermarkets and they were from Spain. The biggest grapefruits that were being sold at “Maxima” supermarkets during the research weighted 493.0 g, but the juiciest ones were bought from “Prisma” supermarket, with the highest amount of juice 44.6%; they were from Greece.
The main conclusion: It was found during the research that citrus fruits (oranges, lemons and tangerines) from Spain were the juiciest; nevertheless, they were also the smallest ones compared to others from different... [to full text]
