O objetivo deste trabalho foi avaliar o efeito da poeira de cimento no crescimento, nos teores de clorofila e de bioelementos em Schinus terebinthifolius Raddi (Anacardiaceae). Para tanto, dois grupos de plantas com 12 meses de idade foram selecionados, um para controle e o outro para ser submetido à poeira de cimento. Um total de 900g de poeira foi pulverizado durante cinco meses, em duas aplicações semanais. Em ambos os grupos de plantas foram realizadas avaliações visuais periódicas para detecção de possíveis anomalias. Foram avaliados também o crescimento em altura, a área foliar, as massas fresca e seca das folhas, a composição química das folhas e a concentração de clorofila. As plantas pulverizadas apresentaram sintomas de clorose, seguida de necrose nos ápices foliolares e queda das folhas, além de tortuosidade nos caules. Mostraram também aumento significativo nos teores de clorofilas a, b e total, bem como de macro, micronutrientes, Al e Na, principalmente nas folhas que não passaram pelo processo de lavagem antes da realização das análises. As massas fresca e seca das folhas foram menores nos indivíduos pulverizados. Os resultados indicam que a espécie utilizada apresenta sensibilidade à contaminação com poeira de cimento, podendo ser usada em estudos de biomonitoramento.Palavras-chave: Aroeira-vermelha; poluição, nutrição florestal; biomonitoramento ativo. AbstractGrowth, chlorophyll and bio-elements concentration in seedlings of Schinus terebinthifolius exposed to cement dust. The aim of this work was to evaluate the effect of cement dust on the growth, chlorophyll and bio-elements concentrations in Schinus terebinthifolius Raddi (Anacardiaceae). Two groups of seedlings 12 months-old were selected, one used as a control and the other to be treated with cement dust. A total of 900g of dust was pulverized during five months, twice a week. For both groups of plants periodical visual observations were made to detect possible anomalies. Evaluations of height growth, foliar area, foliar fresh and dry weight, chemical composition of leaves and chlorophyll concentration were also performed. The plants treated with dust presented yellowish leaves, which subsequently became necrotic and felt down. The stems of plants showed disturbance in growth becoming tortuous. The dusted plants also showed significant increase in the concentrations of chlorophylls a, b and total, as well as in macro and micronutrients, Al and Na, mainly in the leaves not rinsed before analysis. Fresh and dry leaves weights were smaller in the dusted plants than in the control ones. The results indicate this species as useful for bio-monitoring studies because of its sensitivity to cement dust contamination.Keywords: Brazilian pepper tree; pollution, forest nutrition; active bio-monitoring.

The Brazilian pepper-tree (Schinus terebinthifolius Raddi) native to Brazil, recently has become an aggressive perennial weed in southern Florida. During a survey in December 1995, a foliar disease was observed on several pepper-tree plants in Palm Beach County. Disease symptoms consisted of dark, reddish-purple necrotic lesions, either with or without dry necrotic centers, that were distributed randomly over the leaf surface. Infected leaf samples from two separate sites were plated on potato dextrose agar (PDA; Difco) and water agar and incubated at 25°C in the dark. A fungus resembling a Rhizoctonia sp. was consistently recovered. To prove Koch's postulates, the fungus was grown on PDA for 10 to 14 days, and the cultures blended in a Waring blender. Metamucil (Procter & Gamble) was added to the mixture at the rate of 0.5% wt/vol, and the suspension was used to spray and inoculate 2- and 3-month-old Brazilian pepper-tree seedlings. Seedlings were sprayed until the inoculum dripped off the foliage and after inoculation were maintained at 100% relative humidity. After 48 h in the dew chamber the inoculated seedlings were moved to a greenhouse bench and examined for infection 5 and 10 days later. Inoculation was completed three times with the leaf lesions occurring 94 to 100%. A Rhizoctonia sp. was recovered from the lesions that appeared on the challenged plants. A determination of the anastomosis group was performed by plating it against the tester isolates of R. solani, AG1-1A, AG2-2IV, AG-3, AG-4, and AG-5. In two separate tests anastomosis (imperfect fusion) (1) was observed between the recovered Rhizoctonia sp. and tester strain AG2-2IV of R. solani. The fungus was identified as R. solani, and this is the first report of R. solani causing a leaf lesion of Brazilian pepper-tree in Florida. The potential of this R. solani as a biological control agent of Brazilian pepper-tree remains to be tested. Reference: (1) B. Sneh et al. Identification of Rhizoctonia Species.

Germination Experiments

Frugivorous birds play a key role in seed dispersal and establishment of a range of plant species, including invasive weeds, such as the Brazilian Pepper Schinus terebinthifolius. The potential of seed dispersal of Schinus by birds with varied feeding behaviours was studied through seed-viability tests and germination experiments using seeds obtained from birds in the field and birds kept in captivity. It was found that seeds collected after gut passage in five bird species in the field had higher proportion of germination as well as higher germination rates compared to the control seeds. Viability of seeds ingested by the Blue-and-yellow Tanager Thraupis bonariensis, which mandibulates seeds before ingesting, was significantly lower than control seeds, while reduction in viability of seeds ingested by the Creamy-bellied Thrush Turdus amaurochalinus was nonsignificant. Seeds ingested by birds in captivity germinated earlier than the control seeds, within 1-2 weeks, and had proportion and germination rates higher than controls. Probably both mechanical and chemical effects play a role in enhancing germination of seeds. In Brazil where both Schinus and avian frugivores had evolved together, the dependence of Schinus on generalist frugivores had been demonstrated in this study, similar to other countries where the invasive Schinus is dependent on native or introduced avian species for its spreading. This finding has important implications for the restoration of human-altered areas in South America, were Schinus is a native pioneer species, as well as for the management and restoration of areas invaded by Schinus elsewhere.

Abstract Medicinal plants have been used for centuries as an alternative treatment for health problems. Schinus terebinthifolius Raddi is a median tree that belongs to the Anacardiaceae family. The antibacterial effect of leaves extract of this plant has already been demonstrated. The objective of this study was to test a substance derived from this plant to be used in pre- and post-milking teat antisepsis. The hydroalcoholic extract of Brazilian pepper tree was used in opposite quarters for twelve consecutive weeks, and commercial iodine was used as control. None of the indices analyzed - black background mug, CMT, intramammary infections, skin health, and teat health - showed a statistical difference between the treatments, suggesting that the plant extract can be used in pre- and post-milking teat antisepsis, as a substitute for conventional products for herds in an agroecological production system.
