“…Nesta pesquisa, apenas 26 espécies demonstraram valores de IR iguais ou superiores a 1,0 (dentre essas, três eram cultivadas). No entanto, dessas espécies de plantas com importância relativa elevada (acima de 1,0), apenas 10 foram listadas nos trabalhos de Carneiro e dos Santos (2013Santos ( , 2014 que reuniram as plantas medicinais da flora do centro oeste do Brasil, de forma que as outras 16 espécies de alta importância relativa não foram mencionadas nessas obras desses autores.…”

Os povos guarani e kaiowá travam, no centro oeste do Brasil, uma batalha contra o roubo de suas terras tradicionais pelo agronegócio que é imperante na região, fazendo com que a luta em defesa de seus territórios seja marcada por estratégias complexas baseada na valorização de seus conhecimentos tradicionais. Com base na análise da literatura disponível, realizamos uma leitura crítica das evidências disponíveis para fornecer um bom cenário dos estudos etnobotânicos para com esses povos, e assim confeccionamos uma matriz de dados com informações sobre as espécies encontradas. Encontramos sete trabalhos sobre plantas medicinais utilizadas por esses povos, com um total de 209 espécies de plantas, incluídas em 175 gêneros e 73 famílias. Concluímos que, apesar da importância desse tema para esses povos, não há grande número de estudos etnobotânicos disponíveis, sendo necessário organizar esforços para preencher lacunas em diferentes áreas do conhecimento e aperfeiçoar a busca por estratégias que possibilitem aos guarani e kaiowá a existência a partir de um modo de vida específico, que respeita as florestas, as águas, as terras e os demais seres vivos.

(Pasa et al 2005;Carneiro et al 2014;Mizrahi 2014; as Cereus peruvianus), which occur in Northeast Brazil. Many species of Cactaceae show high degrees of parallel evolution in vegetative, fruit and floral traits, which bring a convergence of uses (Barthlott & Hunt 1993).…”

Unveiling the germination requirements for Cereus hildmannianus (Cactaceae), a potential new crop from southern and southeastern Brazil

Cereus hildmannianus K. Schum is a columnar cactus native to South and Southeast Brazil. The cultivation of this species seems justifiable for several reasons: its fruits are spineless and edible; it is not threatened with extinction; it naturally occurs in Pampa and Atlantic Forest under non-xeric conditions that may be unsuitable for the cultivation of other tropical cacti; and the plants are pollinator-dependent and so should benefit from native pollinators. This study aimed to test seed germination of C. hildmannianus with samples collected at three different localities in southern Brazil, as a necessary step preceding any attempts of management and domestication. Seeds were exposed to temperatures of 20° C, 25° C, 30° C and room temperature. The germinability, average germination time and synchronization index were calculated. All samples showed higher germinability at 20° C and 25° C. Seeds from Caçapava do Sul and Santiago showed significant variation in the synchronization index at 25° C and 30° C, respectively. Seeds from Porto Alegre had maximum germinability, indicating greater vigor. Our results show that the seeds of C. hildmannianus germinate well and thrive within a wide range of temperatures and that cultivation of the species from seed-raised plants should not be problematic.

“…The Brazilian flora is world renowned for the pharmacological potential of its plants, due to their medicinal properties, in addition to their wellknown culinary and toxic properties, attracting the attention of researchers from different areas of knowledge (Carneiro and Dos Santos 2014). While much has been studied about the pharmacological and toxicological aspects of Brazilian plants, few studies address the possible ecological interactions that are mediated by secondary metabolites produced by these plants.…”

Sandwich method applied to the screening of allelopathic action in Byrsonima spp. (Malpighiaceae)

In order to understand the allelochemical action of Byrsonima intermedia A. Juss. and B. verbascifolia Rich. ex A. Juss., the effects on germination, initial growth and cell cycle of Lactuca sativa L., exposed to leaves and fruits of this species, were evaluated using the sandwich method. Data were subjected to analysis of variance and means were compared by the Scott-Knott test (p < 0.05). For the parameters germination percentage and germination rate index, no difference between Byrsonima spp. was observed, and B. intermedia fruits were responsible for the highest inhibition of lettuce germination, compared to the leaves. Root elongation in lettuce exposed to B. verbascifolia organs showed stimulatory effects and B. intermedia organs showed inhibitory effects on root growth. The mitotic index showed the allelopathic effect of Byrsonima spp. by the reduction in cell division in lettuce root meristem, and the stimulus in root elongation was caused by B. verbascifolia, understood as a consequence of cell expansion, not mitotic activity. An aneugenic effect of Byrsonima spp. was observed, and the highest frequency of C-metaphase and stickness was found in B. verbascifolia fruits and B. intermedia leaves.
