Ultrastructural characterization of apospory in Panicum maximum

Sexual Plant Reproduction, 1995
The nucellar ultrastructure of apomictic Panicum maximum was analyzed during the meiocytic stage and during aposporous embryo sac formation. At pachytene the megameiocyte shows a random cell organelle distribution and sometimes only an incomplete micropylar callose wall. The chalazal nucellar cells are meristematic until the tetrad stage. They can turn

APOMIXIS IN PANICUM MAXIMUM

American Journal of Botany, 1954
INDICATIONS OF SOME break-down or by-pass of sexual reproduction were observed in recent cytotaxonomic studies of guinea grass (Panicum maximum Jacq.) from Puerto Rico. In this species, which is autotetraploid and characterized by considerable meiotic irregularity and chromosome nondisjunction in microsporogenesis, seedling progenies in experimental ...

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.

The regulation of starch accumulation inpanicum maximumJacq. by nitrogen

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1981
Electron microscopic studies of Panicum maximum (PCK C4 photosynthetic type) when grown under controlled growth conditions as low nutrient nitrogen (20 ppm N, KNO3) showed interesting second order bundle sheath cell organisation: the cells were several times bigger than the mesophyll cells and were packed with starch grains.

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.

Xylans from the tropical grass Panicum maximum

Phytochemistry, 1974
Abstract Two xylans have been isolated from the mature tissues of the tropical grass Panicum maximum —an arabino(4- O -methylglucurono)xylan and an acidic galactoarabinoxylan. Both consist of a main chain of β(1 → 4) linked d -xylopyranosyl residues.

Co. 1 GUINEA GRASS (PANICUM MAXIMUM JACG.)

Madras Agricultural Journal, 1994
The germplasm types of Guine sagrass in the Tamil Nadu Agricultural University. Coimbatore were evaluated for green fodder yield during 1980-82 along with the local variety. Six selections were found promising in 1982-83 and preliminary yield trials were conducted from 1985 to 1988.
