Dorsoventral variations in dark chilling effects on photosynthesis and stomatal function in Paspalum dilatatum leaves
The effects of dark chilling on the leaf-side-specific regulation of photosynthesis were characterized in the C(4) grass Paspalum dilatatum. CO(2)- and light-response curves for photosynthesis and associated parameters were measured on whole leaves and on each leaf side independently under adaxial and abaxial illumination before and after plants were exposed to dark chilling for one or two cons...
متن کاملEects of Flooding and Drought on the Anatomy of Paspalum dilatatum
0305-7364/0 * For corre { Present Durham, NC Paspalum dilatatum occupies dierent topographic positions in the Flooding Pampa, Argentina. Populations from dierent positions are subjected to various regimes of ̄ooding and drought, both of which may occur in the same growing season. We investigated the constitutive and plastic anatomical traits of P. dilatatum populations from habitats with contr...
متن کاملCytology and reproductive behavior of hybrids between Paspalum urviUei and two hexaploid P. dilatatum biotypes
Sexual, tetraploid (2n = 4x = 40) vaseygrass (Paspalum urvillei Steud.) was crossed with two apomictic, hexaploid (2n = 6x = 60) dallisgrass (P. dilatatum Poir.) biotypes (Uruguayan and Uruguaiana) to determine their relationships and the reproductive behavior of the hybrids. One vaseygrass x Uruguayan and two vaseygrass x Uruguaiana hybrids were studied and all had 2n = 5x = 50 chromosomes. Th...
متن کاملGene Discovery and Molecular Marker Development, Based on High-Throughput Transcript Sequencing of Paspalum dilatatum Poir
BACKGROUND Paspalum dilatatum Poir. (common name dallisgrass) is a native grass species of South America, with special relevance to dairy and red meat production. P. dilatatum exhibits higher forage quality than other C4 forage grasses and is tolerant to frost and water stress. This species is predominantly cultivated in an apomictic monoculture, with an inherent high risk that biotic and abiot...
متن کاملGrowth of seashore paspalum, (Paspalum vaginatum L) in soil contaminated with crude petroleum oil
The effect of crude oil contaminated soil on the growth of seashore Paspalum ( Paspalum vaginatum .) seedlings was investigated. Plants were grown in soil containing different concentrations: 0%, 0.5%, 1.0%, 2.0% and 3% (w/w) of Abura crude petroleum oil. Growth parameter such as shoot number, shoot length, leaf area and biomass accumulation were evaluated. The results showed that crude oil imp...
