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...

the effects of 450-days of flooding on morphological and gas exchanges responses were investigated under controlled conditions for populus deltoides (colon 77.51) and taxodium distichum seedlings. seedlings were subjected to three outdoor treatments: not flooded (control), flooded to 3 cm above the soil surface (shallow flooded), and flooded to 15 cm above the soil surface (deep flooded). flood...

Se describe una nueva especie, Cecidomyia lamellata Gagné, de adultos de ambos sexos, pupas y larvas recolectados de la resina en ramas engrosadas de ciprés, Taxodium distichum (L.) Rich. (Taxodiaceae) en Fort Pierce, Florida. Algunos caracteres anatómicos de la especie nueva son distintos de los limites conocidos para este género. El ciprés es el primero hospedero conocido de Cecidomyia que no...

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...
