Invasive Melinis minutiflora outperforms native species, but the magnitude of the effect is context-dependent

Biological Invasions, 2018
Impacts of invasive species are context-dependent owing to genetic differences in the invasive species, in the abiotic environment or the recipient biotas. Here, we tested how these factors affected the invasive grass Melinis minutiflora and its impacts on native plants in Hawai’i (USA) and in the Brazilian Cerrado under four environmental conditions ...

Anti-tick effects of Melinis minutiflora and Andropogon gayanus grasses on plots experimentally infested with Boophilus microplus larvae

Experimental and Applied Acarology, 2004
Our objective in this trial was to investigate the anti-tick effects of molasses grass (Melinis minutiflora) and gamba grass (Andropogon gayanus) against Boophilus microplus, using buffel grass (Cenchrus ciliaris) as a control. During a 3-year-period fieldwork was carried out in the tropical, subhumid climate at Progreso, Municipality of Jiutepec ...

Repellence of the tickRhipicephalus appendiculatus by the grassMelinis minutiflora

Tropical Animal Health and Production, 1995
In a study to develop anti-tick pastures, the climbing behaviour of Rhipicephalus appendiculatus on Melinis minutiflora (molasses grass) was investigated. Experiments were done with cut green stems of grass, grass dried in the shade, grass dried in sunshine, grass washed in solvent and grass growing in a study plot. In all cases a common pasture grass,

Diurnal variations of non-structural carbohydrates in vegetative tissues of Melinis minutiflora, Echinolaena inflexa and Lolium multiflorum (Poaceae) [PDF]

Revista Brasileira De Botanica, 2005
Echinolaena inflexa (Poir.) Chase is a native C3 grass species with high biomass production and abundance in the cerrado comparable to Melinis minutiflora Beauv., a C4 forage grass of African origin, widespread in the cerrado, displacing some native herbaceous species. These species accumulate mainly starch, differently of Lolium multiflorum Lam.

Constraints to colonization and growth of the African grass, Melinis minutiflora, in a Venezuelan savanna

Plant Ecology, 2003
Melinis minutiflora Beauv. (Poaceae) is an African grass that is invading mid-elevation Trachypogon savannas in Venezuela. The objective of this study was to investigate the influence of soil fertility, competition and soil disturbance in facilitating Melinis' invasion and growth in these savanna sites. We manipulated soil fertility by adding nitrogen (

Obtaining and characterizing polyphenol extracts based on anthocyanins from Melinis minutiflora inflorescences and Plinia cauliflora fruits and application in gelatins

Food Research International, 2023
Anthocyanins are a class of compounds potentially used as food dyes. Thus, this study aimed to obtain and characterize natural extracts from Melinis minutiflora inflorescence (M), Plinia. cauliflora peel (JP) and P. cauliflora peel and seeds (JPS) and apply them as natural food dyes in gelatins.

The invasive grass, Melinis minutiflora, inhibits tree regeneration in a Neotropical savanna

Austral Ecology, 2008
Abstract  Exotic grasses are becoming increasingly abundant in Neotropical savannas, with Melinis minutiflora Beauv. being particularly invasive. To better understand the consequences for the native flora, we performed a field study to test the effect of this species on the establishment, survival and growth of seedlings of seven tree species native to

Effects of Molasses Grass, Melinis minutiflora Volatiles on the Foraging Behavior of the Cereal Stemborer Parasitoid, Cotesia sesamiae

Journal of Chemical Ecology, 2003
Olfactory responses of the cereal stemborer parasitoid Cotesia sesamiae to volatiles emitted by gramineous host and nonhost plants of the stemborers were studied in a Y-tube olfactometer. The host plants were maize (Zea mays) and sorghum (Sorghum bicolor), while the nonhost plant was molasses grass (Melinis minutiflora). In single-choice tests, females

Close-Range Host Searching Behavior of the Stemborer Parasitoids Cotesia sesamiae and Dentichasmias busseolae: Influence of a Non-Host Plant Melinis minutiflora

Journal of Insect Behavior, 2005
Studies were conducted on the host searching behavior of the larval parasitoid Cotesia sesamiae (Cameron) (Hymenoptera: Braconidae) and the pupal parasitoid Dentichasmias busseolae Heinrich (Hymenoptera: Ichneumonidae), both of which attack lepidopteran (Crambidae, Noctuidae) cereal stemborers. The behavior of D. busseolae was observed in a diversified

Determinação do modo de reprodução em capim-gordura (Melinis minutiflora Beauv.) por padrões enzimáticos [PDF]

Ciencia Rural, 1996
Com o objetivo de determinar o modo de reprodução do capim-gordura (Melinis minutiflora Beauv.), 24 ecótipos da coleção da Universidade Federal de Viçosa foram utilizados em cruzamentos, após emasculação massal por imersão da inflorescência em água quente, testando-se quatro faixas de temperatura. Analisaram-se, comparativamente, os padrões de isozimas
