The evaluation of four Eragrostis curvula ecotypes with grazing sheep.

African Journal of Range and Forage Science, 1990
Four ecotypes of Eragrostis curvula, namely, Cape Province 5, Ermelo, Pearston 204 and Makwassie 150 were evaluated in a grazing trial with sheep, at three stocking rates, during two growing seasons. Under conditions of very lenient utilization, where the animals could select freely, the animals on Cape Province 5 had significantly higher mass gains ...

Seasonal response of Eragrostis curvula to nitrogen

African Journal of Range and Forage Science, 1975
On the basis of the seasonal response of Eragrostis curvula to nitrogen applied as single dressings to separate plots at the beginning of each of the six months of the growing season, it is deduced that nitrogen can profitably be applied in the Ukulinga environment from early spring though to early January.

Variation in cytosine methylation patterns during ploidy level conversions in Eragrostis curvula

Plant Molecular Biology, 2009
In many species polyploidization involves rearrangements of the progenitor genomes, at both genetic and epigenetic levels. We analyzed the cytosine methylation status in a 'tetraploid-diploid-tetraploid' series of Eragrostis curvula with a common genetic background by using the MSAP (Methylation-sensitive Amplified Polymorphism) technique. Considerable

Biolistic-mediated transformation of Eragrostis Curvula with the HSP 12 gene

, 2003
Eragrostis curvula is a desiccation sensitive monocotyledonous plant and an economically important forage grass in southern Africa. This species has a potential to be improved for drought and salt resistance among other important agronomic traits. In this study, E.

Predicting seasonal production of eragrostis curvula

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1980
The potential for mathematical prediction of the yield and quality of forage crops in fodder production planning is still untapped. This paper presents a multiple regression equation accounting for 88% of the variation that occurred in some 270 individual annual yields of Eragrostis curvula.

Overseeding ofEragrostis curvulaon north‐eastern Sandy Highveld

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1973
A small plot trial to investigate the possibilities of directing changes in the botanical composition of fertilized veld by oversowing demonstrated the potential of this technique for the establishment of improved pastures in non-arable situations. The improved return on fertilization, obtained by this technique, can also radically alter the attitude ...

Epicuticular wax of Eragrostis curvula

Phytochemistry, 1982
Abstract Epicuticular wax of Eragrostis curvula contains hydrocarbons (6%), esters (13%), acids (3%), alkanols (4%), tritriacontane-12,14-dione (47%), 5(S)-5-hydroxytritriacontane-12,14-dione (14%) as major components. The esters consist of triterpenol esters (42%) as well as alkanol esters. The free alkanols consist principally Of C16C32 components,

Isozyme variation and germplasm relationships in the Eragrostis curvula complex

Biochemical Systematics and Ecology, 1997
Abstract Eragrostis curvula germplasm includes a diversity of forms whose biosystematic relationships remain obscure. Because the E. curvula complex reproduces primarily by apomixis, morphological characters may be insufficient to assess biological affinities among them.

Facultative Apomixis in Eragrostis curvula¹

Crop Science, 1976
Previous reports indicate that weeping lovegrass, [Eragrostis curvula (Schrad.) Nees], reproduces either sexually or by obligate apomixis (diplospory). Recent studies have shown that certain plants of this species are facultative apomicts. Our research objective was to determine the cytological basis for facultative apomixis in weeping lovegrass and to
