Beginning with funding from the USGA in 1993, a dedicated effort was initiated to genetically enhance seashore paspalum for golf course use. The grass has been around for centuries, actually evolving on sand dunes exposed only to ocean water in South Africa. It's somewhat ironic that this grass evolved in the same country as the African bermudagrass, but was never recognized for anything other ...

Somatic chromosome numbers were determined for 20 new germplasm accessions of Paspalum, belonging to 17 species collected in Brazil. Chromosome number is reported for the first time for P. reduncum (2n = 18), P. cinerascens (2n = 20), P. cordatum (2n = 20), P. filgueirasii (2n = 24), P. ammodes (2n = 36), P. bicilium (2n = 40), P. heterotrichon (2n = 40), and P. burmanii (2n = 48). New cytotype...

FLUCTUACIONES TEMPORALES DE LA BIOMASA Y CONTENIDO ALMIDÓN PASPALUM FASCICULATUM

Anther and pollen development were studied in Olyra humilis Nees, Sucrea monophylla Soderstr, (Bambusoideae), Axonopus aureus P. Beauv., Paspalum polyphyllum Nees ex Trin. (Panicoideae), Eragrostis solida Nees, and Chloris elata Desv. (Chloridoideae). The objective of this study was to characterise, embryologically, these species of subfamilies which are considered basal, intermediate and deriv...

In lepton-number-violating supersymmetric models, there is no natural choice of basis to distinguish the down-type Higgs and lepton superfields. We employ basis-independent techniques to identify the massless majoron and associated light scalar in the case of spontaneously-broken lepton number (L). When explicit L-violation is added, these two scalars can acquire masses of order the electroweak...

Cadmium (Cd) is considered to be one of the most toxic metals, causing serious harm plants’ growth and humans’ health. Therefore, it necessary study simple, practical, environmentally friendly methods reduce its toxicity. Until now, people have applied zinc sulfate improve Cd tolerance plants. However, related studies mainly focused on physiological biochemical aspects, with a lack in-depth mol...
