Estudo sôbre as temperaturas médias em Campinas

This paper deals with the study by orthogonal polynomials of trends in the mean annual and mean monthly temperatures (in degrees Centigrade) in Campinas (State of São Paulo, Brasil), from 1890 up to 1956. Only 4 months were studied (January, April, July and October) taken as typical of their respective season. For the annual averages both linear and quadratic components were significant, the regression equation being y = 19.95 - 0.0219 x + 0.00057 x², where y is the temperature (in degrees Centigrade) and x is the number of years after 1889. Thus 1890 corresponds to x = 1, 1891, to x = 2, etc. The equation shows a minimum for the year 1908, with a calculated mean y = 19.74. The expected means by the regression equation are given below. Anual temperature means for Campinas (SP, Brasil) calculated by the regression equation Year Annual mean (Degrees Centigrade) 1890 19.93 1900 10.78 1908 19.74 (minimum) 1010 19.75 1920 19.82 1930 20.01 1940 20.32 1950 20.74 1956 21.05 The mean for 67 years was 20.08°C with standard error of the mean 0.08°G. For January the regression equation was y = 23.08 - 0.0661 x + 0.00122 x², with a minimum of 22.19°C for 1916. The average for 67 years was 22.70°C, with standard error 0.12°C. For April no component of regression was significant. The average was 20.42°C, with standard error 0.13°C. For July the regression equation was of first degree, y = 16.01 + 0.0140X. The average for 67 years was 16.49°C, with standard error of the mean 0.14°C. Finally, for October the regression equation was y = 20.55 - 0.0362x + 0.00078x², with a minimum of 20.13°C for 1912. The average was 20.52°C, with standard error of the mean equal to 0.14°C.

Duas plantas hospedeiras novas do nematóide Meloidogyne Coffeicola

Coffea dewevrei var. excelsa and Coffea canephora var. robusta are recorded as new hosts for Meloidogyne coffeicola (Nemata, Heteroderidae). Robusta coffee was found also attacked by M. javanica. Symptoms shown by roots are described.

Novas pesquisas sobre as plantas hospedeiras do nematóide do cafeeiro, Meloidogyne exigua Goeldi, 1887

Foram realizadas provas para conhecer a reação de 54 culturas e 34 ervas más ao nematóide Meloidogyne exigua. Nenhuma planta se revelou sensível ao parasito, apresentando-se atacadas apenas as variedades de Coffea arabica e um híbrido de C. arabica e C. excelsa.

Concentrações de alguns macro e micronutrientes em essências florestais do parque da Escola Superior de Agricultura «Luiz de Queiroz»

Em cinco árvores do parque da Escola Superior de Agricultura "Luiz de Queiroz", pertencentes às espécies, Aspidospernia polyneuron Müell, Cariniana estrellensis Raddi, Paratecoma peroba Record, Aleurites moluccana Wield e Piptadenia rígida, foram coletadas três amostras constituídas de folhas consideradas novas, medianas e velhas, aparentemente. As 15 amostras obtidas foram lavadas para micronutrientes, secadas em estufa a aproximadamente 70ºC, moídas e analisadas sob três repetições, quanto a seus teores em N, R, K, Ca, Mg, Cu, Fe, Mn e Zn. O delineamento experimental utilizado foi o inteiramente casualizado, e as diferenças estatísticas significativas entre as médias dos vários tratamentos, detectadas pela análise de variância, foram comparadas através do teste Tukey. Os seguintes contrastes puderam ser observados : a) Pelo menos uma árvore dentre as cinco, diferiu das demais quanto à concentração relativa de cada um dos nutrientes considerados . b) Em todas as árvores estudadas, com exceção da pertencente à espécie Aleurites moluccana (nogueira de Iguape), os nutrientes constatados em maior concentração foram o N e o Ca, enquanto que, na nogueira detectou-se maior concentração de N e K. c) Piptadenia rígida (angico branco) e Cariniana estrellensis (jequitibá branco) mostraram concentrações particularmente elevadas de Fe. d) Genericamente, as folhas novas das essências observadas apresentaram tendência de possuírem maiores concentrações de N, R, K e Cu, enquanto as folhas velhas mostraram maiores concentrações de Ca e Mn.
