Comportamento do cafeeiro apoatã em consórcio com culturas anuais

This study was conducted in Adamantina, region of Alta Paulista, São Paulo State, Brazil, from 1989 to 1993. Yield of Apoatã coffee (Coffea canephora Pierre ex Froehner) was evaluated during four years of intercropping with five plant species: IAC 20 - cotton (Gossypium hirsutum L.); cv. Tatu - peanut (Arachis hypogaea L.); IAC 165 - rice (Oryza sativa L.); cv. Guarani - castor bean (Ricinus communis L.) and IAC 100-B - corn (Zea mays L.). The crops were seeded 50 cm apart from coffee canopy. The treatments were arranged in randomized complete block design with five replications. Yield was significantly decreased when coffee was intercropped with castor bean, corn, cotton and peanut, but height and diameter of orthotropic branches were not affected. Linear correlation analysis showed that coffee yield was inversely correlated with the dry biomass of the intercrops.

Exposição de culturas de fibroblastos de pterígios primários e recidivados à mitomicina c e ao 5-fluorouracil

Purpose: To evaluate the proliferation of the fibroblasts from primary and recurrent pterygium in culture of cells, after the exposure to mitomycin C and to 5-fluorouracil. Methods: Cultures of fibroblasts from primary and recurrent pterygiuns had been carried through. The cells of the third passage were exposed to mitomycin C 0.4% during 3 minutes and to 5-fluorouracil 25mg/ml that was kept in the nutritional medium. After 3, 6, 12 and 18 days of the exposure, cell countings were made in hemocytometer, in triplicate, with a control not treated with the drugs for each day. The data were submitted to statistical analysis.Results: Mitomicyn C had homogeneous behavior in the primary and recurrent groups, which inhibited the cellular proliferation since the first counting day. However, with 5-fluorouracil, the proliferation inhibition was verified only after the third day of evaluation (in the second counting day) in the recurrent group, and since the first counting day in the primary group. At the end of the experimental period, 5-fluorouracil and mitomycin C were equally efficient in the inhibition of the fibroblasts from primary and recurrent pterygium proliferation. In the controls not exposed, the cell's numbers were increasing during the experimental time.Conclusion: Mitomycin and 5-fluorouracil are equally able to inhibit fibroblasts proliferation from primary and recurrent pterygium Tenon's capsule in cell culture.

Propagação in vitro de Cattleya trianaei (Linden & Reichenbach fil.) (Orchidaceae) em meios de culturas e com doses de fertilizante comercial

The use of culture media produced with commercial fertilizers can represent a simple and low cost alternative for commercial orchid propagation. The aim of this study was to evaluate the in vitro growth of plantlets of Cattleya trianaei in culture medium MS reduced and and formulated with Peters® NPK 10-30-20 in different doses. 90 day-old plantlets with two leaflets were submitted to five treatments (T1 - reduced MS; T2 - Peters® 1 g L -1; T3 - Peters® 2 g L-1; T4 - Peters® 3 g L -1 and T5 - Peters® 5 g L-1) arranged in a completely randomized design with five replicates with 25 plantlets for each treatment and incubated during 180 days, with subcultures at each 60 days, when the number of roots, root length, number of leaves, shoot length and shoot fresh matter were evaluated. The simplified culture medium with fertilizer Peters® 3 g L -1 presented results statistically different as for the number of roots, number of leaves, shoot length and shoot fresh matter and it can be recommended for in vitro growth of this ornamental orchid.
