Tagetes minuta and Schinus areira essential oils as allelopathic agents
TLDR
The bioassay of T. minuta and S. areira oils and their pure principal components revealed strong inhibitory activity of the root growth of Zea mays seedlings and the main components of the essential oils presented an increase in malondialdehyde values from 24 to 48 h indicating lipid peroxidation.

Essential oil composition of Bothriochloa Kuntze (Poaceae) from South America and their chemotaxonomy
TLDR
Multivariated statistical analysis applied to GC–MS data seems to have systematic significance for the delimitation of the species, independently of their morphological characteristics. Expand
Reproductive biology of South American Bothriochloa (Poaceae: Andropogoneae)
TLDR
Several elements point to self-pollination as their main breeding system: bud pollination that occurs in most species enhancing cleistogamy, presence of pits in the glumes that impede the opening of flowers and reduction in the number of stamens, a trend associated with outbreeding. Expand
The foveola of Bothriochloa alta (Poaceae: Andropogoneae): Extrafloral nectary or secretory gland of essential oils?
TLDR
The results show that the foveola functions as a secretory cavity producing essential oils instead of being an extrafloral nectary as previously suggested. Expand
Allelopathic effect of endemic South American Bothriochloa species (Poaceae: Andropogoneae)
TLDR
The aqueous extracts from different plant parts of three species of Bothriochloa inhibited the seed germination and root and shoot growth of test species and indicated the phytotoxic activity of extracts. Expand
Phenotypical variation and taxonomic correlates of five closely related Andean species of Poa (Poaceae) along geographic and climatic gradients
TLDR
Morphological variation is explained by geographical and climatic factors such as elevation, geographical distance, latitudinal and longitudinal gradients, temperature and precipitation in the different sites in the Andes. Expand
Delimiting species boundaries within the Bothriochloa saccharoides complex (Poaceae) through morphometric analysis
TLDR
Five taxa could be distinguished on the basis of morphological characters and chemical data and two new subspecies are described: B. saccharoides subsp. Expand
Chromosome number in South American species of Bothriochloa (Poaceae: Andropogoneae) and evolutionary history of the genus.
TLDR
Mitotic chromosome number of 14 taxa of Bothriochloa native to Argentina, Brazil and Uruguay were surveyed and new cytotypes were found for B. velutina, which is the most common among the studied taxa. Expand
Allelopathic potential of South American Bothriochloa species (Poaceae: Andropogoneae)
TLDR
In laboratory bioassays the aqueous extracts from different plant parts of six Bothriochloa species inhibited the seed germination and root and shoot growth of lettuce, maize, wintergreen paspalum, and lovegrass and indicated the phytotoxic activity of extracts. Expand
