Nitrogênio e potássio no crescimento de mudas de pitaia [Hylocereus undatus (Haw.) Britton & Rose]

A pitaia ainda é uma cultura carente de estudos e informações que subsidiem a definição/adaptação de sistemas de produção mais adequados às condições edafoclimáticas brasileiras, embora nos últimos anos tenha havido aumento de sua expansão agrícola, tanto no Brasil quanto em outros países. Assim, o objetivo deste estudo foi avaliar o efeito da adubação mineral sobre o crescimento de mudas de pitaia e, dessa maneira, obter informações direcionadas para a definição de manejos de fertilização adequados à exploração agrícola da cultura. Para isto, foram testadas cinco doses de nitrogênio (N) (0; 150; 300; 450 e 600 mg dm-3) e potássio (K) (0; 75; 150; 225 e 300 mg dm-3), sendo os níveis de cada nutriente arranjados em esquema fatorial 5x5, com quatro blocos. Para a interação significativa a (p<0,05), procedeu-se ao ajuste em superfícies de resposta do tipo Y = β0 + β1(A) + β2(A)² + β3(B) + β4(B)² + β5(A).(B) + e. As estimativas das correlações fenotípicas foram obtidas considerando apenas o intervalo das doses de N e K, que promoveram as melhores respostas do acesso de pitaia para os caracteres estudados. Ao término do presente estudo, foi constatado que a aplicação de doses crescentes de N e K, e a interação NxP afetam os teores de ambos os nutrientes no solo, o sistema radicular e a parte aérea, influenciando, desse modo, sobre o crescimento inicial das plantas de pitaia. Os rendimentos mais satisfatórios ocorrem quando há 0,7 mmol dm-3 de K no solo, e 20 - 25 g kg-1 de N com 30 - 40 g kg-1 de K na parte aérea. Esses valores foram obtidos para a aplicação de 300 - 450 mg dm-3 de N com 150 - 225 mg dm-3 de K. O somatório do comprimento dos cladódios (SCC) e a massa seca do sistema radicular (MSSR) são as variáveis explicativas que apresentam maiores efeitos diretos sobre a massa seca dos cladódios (MSC).

The Rose Bengal test in human brucellosis: a neglected test for the diagnosis of a neglected disease

Brucellosis is a highly contagious zoonosis affecting livestock and human beings. The human disease lacks pathognomonic symptoms and laboratory tests are essential for its diagnosis. However, most tests are difficult to implement in the areas and countries were brucellosis is endemic. Here, we compared the simple and cheap Rose Bengal Test (RBT) with serum agglutination, Coombs, competitive ELISA, Brucellacapt, lateral flow immunochromatography for IgM and IgG detection and immunoprecipitation with Brucella proteins. We tested 208 sera from patients with brucellosis proved by bacteriological isolation, 20 contacts with no brucellosis, and 1559 sera of persons with no recent contact or brucellosis symptoms. RBT was highly sensitive in acute and long evolution brucellosis cases and this related to its ability to detect IgM, IgG and IgA, to the absence of prozones, and to the agglutinating activity of blocking IgA at the pH of the test. RBT was also highly specific in the sera of persons with no contact with Brucella. No test in this study outperformed RBT, and none was fully satisfactory in distinguishing contacts from infected patients. When modified to test serum dilutions, a diagnostic titer >4 in RBT resulted in 87.4% sensitivity (infected patients) and 100% specificity (contacts). We discuss the limitations of serological tests in the diagnosis of human brucellosis, particularly in the more chronic forms, and conclude that simplicity and affordability of RBT make it close to the ideal test for small and understaffed hospitals and laboratories.

Pedagogies de la liquiditat

«Escriu més ràpid del que jo puc llegir», va dir Nikolas Rose el Convenor del departament de sociologia de la London School of Economics and Political Science referint-se a Zygmunt Bauman. Ho va dir en el brindis de la recepció que aquest departament va oferir després de la darrera de les tres lliçons que Bauman va explicar durant el mes de novembre de 2005 a l"Old Theather de la LSE, i l"anècdota no és debades. La crítica recurrent en àmbits acadèmics com ara l"espanyol, segons la qual els darrers llibres de Bauman no fan altra cosa que parafrasejar la idea afortunada de la modernitat líquida, també és compartida a l"acadèmica britànica. I a més, com és habitual en aquelles contrades, es comenta sense embuts en presència de la persona implicada. Que quedi palès, doncs, que aquest text no serà pas un pretext per fer-li un panegíric. Ara bé, les coses com són, malgrat que s"hagi acusat Bauman d"engiponador i a banda de l"abundància de llibres publicats, i la reiteració constant d"algunes idees cal dir que els seus continguts no deixen de ser reveladors, alhora que reclamen l"atenció, per a totes les ciències socials.

Gray mold severity and vase life of rose buds after pulsing with citric acid, salicylic acid, calcium sulfate, sucrose and silver thiosulfate

Gray mold of roses (Rosa hibrida) caused by Botrytis cinerea requires many management strategies for its control. The effect of pulsing rose cv. Kiss with solutions of citric acid, salicylic acid, sucrose, calcium sulfate, and silver thiosulfate (STS) on disease severity and vase life of the flowers was evaluated. The solutions were applied to cut stems at different stages of harvest, the variation in the opening stage of harvest did not affect the results. Pulsing with STS reduced the values of area under the disease progress curve (AUDPC) and of severity of disease by 15% and 55%, respectively, and increased the vase life of the flowers by 20%. Calcium sulfate consistently reduced AUDPC by 66% and maximum severity by 88%, and increased vase life of the flowers by 37%. Therefore, pulsing rose buds with solutions of STS and calcium sulfate is potentially useful in reducing losses due to gray mold after harvest and in extending the vase life.

Survival of Botrytis cinerea as mycelium in rose crop debris and as sclerotia in soil

Botrytis blight caused by Botrytis cinerea is an important disease of rose (Rosa hybrida) grown in greenhouses in Brazil. As little is known regarding the disease epidemiology under greenhouse conditions, pathogen survival in crop debris and as sclerotia was evaluated. Polyethylene bags with petals, leaves, or stem sections artificially infected with B. cinerea were mixed with crop debris in rose beds, in a commercial plastic greenhouse. High percentage of plant parts with sporulation was detected until 60 days, then sporulation decreased on petals after 120 days, and sharply decreased on stems or leaves after 90 days. Sporulation on petals continued for 360 days, but was not observed on stems after 150 days or leaves after 240 days. Although the fungus survived longer on petals, stems and leaves are also important inoculum sources because high amounts of both are deposited on beds during cultivation. Survival of sclerotia produced on PDA was also quantified. Sclerotia germination was greater than 75% in the initial 210 days and 50% until 360 days. Sclerotia weight gradually declined but they remained viable for 360 days. Sclerotia were produced on the buried petals, mainly after 90 days of burial, but not on leaves or stems. Germination of these sclerotia gradually decreased after 120 days, but lasted until 360 days. Higher weight loss and lower viability were observed on sclerotia produced on petals than on sclerotia produced in vitro

Biotransformation of citronellol in rose-oxide using cassava wastewater as a medium

The use of liquid cassava waste (manipueira) as the medium for the biotransformation of citronellol using a Penicillium sp strain was studied. The strain was able to grow in the waste and production of cellular mass reaching 25 g/L over three days of contact of the spores with the medium. Submerged cultures of Penicillium sp grown in manipueira were able to convert the substrate into cis- and trans-rose oxides when the cells were transferred into a mineral medium for the biotransformation experiments. The production of rose oxide increased by more than 2.4 times using this 2 media process as compared to processes using only a manipueira medium (cassava medium). Auto-oxidation products were not detected in the control experiments.
