Analysis of expressed sequence tags in apomictic guineagrass (Panicum maximum)

Journal of Plant Physiology, 2009
Apomixis is an intriguing asexual mode of reproduction, because it produces maternal clones that permit vegetative reproduction through seeds. Guineagrass (Panicum maximum) has both facultative aposporous apomixis and obligate sexual modes of reproduction.

Multivariate and multiharvesting trial for agronomic traits in the genetic resources of guineagrass

Agronomy Journal, 2022
AbstractThe diversity and use of forages and grasslands for animal feeding are essential in tropical livestock systems. Seasonal changes are mainly marked by variations in precipitation patterns. Grasslands are managed as perennial crops and therefore must be resilient to tolerate both dry and rainy seasons.

Biology of Sourgrass and Its Competition with Buffelgrass and Guineagrass

Weed Science, 1977
Establishment and early growth characteristics were defined for sourgrass [Trichachne insularis(L.) Nees], one of the most serious pasture weeds in Hawaii. Optimum germination of sourgrass seeds was obtained in the light at 30 C or with alternating temperatures of 20 and 30 C or 25 and 35 C.

Ecotypic differentiation in guineagrass (Panicum maximum Jacq.)

Agro-Ecosystems, 1979
Abstract Six Brazilian populations of guineagrass ( Panicum maximum Jacq.) were studied in order to evaluate their quantitative and allozyme variation and to correlate their ecotypic differences with average monthly temperature and rainfall at the collection sites.

Herbage responses of Tamani and Quênia guineagrasses to grazing intensity

Agronomy Journal, 2020
AbstractNew forage cultivars require defoliation studies for recommending proper grazing management. Our objective was to characterize herbage accumulation (HA), plant‐part composition and nutritive value of guineagrass [Megathyrsus maximus (Jacq.) B. K. Simon & S. W. L. Jacobs] rotationally stocked under two grazing intensities.

Simple agrometeorological models for estimating Guineagrass yield in Southeast Brazil

International Journal of Biometeorology, 2013
The objective of this work was to develop and evaluate agrometeorological models to simulate the production of Guineagrass. For this purpose, we used forage yield from 54 growing periods between December 2004-January 2007 and April 2010-March 2012 in irrigated and non-irrigated pastures in São Carlos, São Paulo state, Brazil (latitude 21°57'42″ S ...
