Schinus terebinthifolius (Anacardiaceae) is among the medicinal species native to Brazil, known as mastic-red and mastic-pepper, whose stem bark is used to fight inflammation of various origins, as it has anti-inflammatory and healing properties. The objective of this study is to explore trends in the publications portrayed on the species S. terebinthifolius, analyzing axes such as time, countries, journals, impact factors and citations, the scientometric approach was used to summarize all the studies on S. terebinthifolius in a single article. 475 publications were used with an average number of 20.8 publications per year, encompassing 68 research areas and published in 220 different journals, covering all retractions visible on the Web of Science from 2001 until May 2021. The most productive country was Brazil with 271 articles, followed by the USA with 105 articles. The methods and results of this study can be applied to continually understand the nature of research on the species.

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.
