Doubling the chromosome number of bahiagrass via tissue culture
Diploid bahiagrass embryogenic callus tissue was exposed to three concentrations of three antimitotic chemical agents, colchicine, oryzalin and trifluralin and the high rates of success indicate that all agents can be successfully used to double chromosome numbers in bahiAGrass. Expand
Harnessing apomictic reproduction in grasses: what we have learned from Paspalum.
BACKGROUND Apomixis is an alternative route of plant reproduction that produces individuals genetically identical to the mother plant through seeds. Apomixis is desirable in agriculture, because itExpand
Tetraploid bahiagrass hybrids: breeding technique, genetic variability and proportion of heterotic hybrids
The objectives were to create a second generation of hybrids by crossing sexual first-generation tetraploid hybrids and unrelated apomictic FGTH or ecotypes, determine the segregation for mode of reproduction, and estimate the resulting genetic variation and heterosis for several agronomic characteristics.

Bahiagrass Tetraploid Germplasm: Reproductive and Agronomic Characterization of Segregating Progeny
Heritability estimates obtained for these characteristics indicate that selection can be successfully used for the genetic improve-ment of this species. Expand
Heterosis and Expressivity of Apospory in Tetraploid Bahiagrass Hybrids
This poster presents a probabilistic assessment of the response of the immune system to the presence of carbon dioxide in the atmosphere over a period of several years. Expand

Reproductive Characterization of Bahiagrass Germplasm
The objective was to determine and compare the mode of reproduction of diploid and tetraploid germplasm of bahiagrass, and define their usefulness for genetic improvement research. Expand
Diversity in Diploid, Tetraploid, and Mixed Diploid–Tetraploid Populations of Paspalum simplex
This research presents a meta-analysing of the response of the immune systems to the presence of carbon dioxide in the environment over a long period of time and shows clear patterns of decline over time. Expand
Potential root depth development and nitrogen uptake by tetraploid bahiagrass hybrids
Rapid root depth development was a determining factor for rapid access and uptake of nitrogen present in deep soil layers, which might explain why clones exhibiting rapid root penetration also showed greater early vigor. Expand
How to Become an Apomixis Model: The Multifaceted Case of Paspalum
The steps adopted in Paspalum to establish the current body of knowledge on apomixis and provide model breeding programs for other agronomically important apomictic crops are reviewed. Expand
