Abstract:

Abstract Ectocarpene, (+)-(6S)-(1Z-butenyl)-2,5-cycloheptadiene, is the mating pherom one of the three distantly related seaweeds Ectocarpus siliculosus, Sphacelaria rigidula and Adenocystis utricularis. Analogu es of this pheromone, differing in position and π-electron density of the double bond in the C4-side chain, were synthesized and assayed for biological activity. The results suggest, that the fundamental molecular recognition process is conservative in all species, while receptor dynamics and -topologies have been modified by individual developments and expressions during plant phyl

In addition, the hypothecium of Neuropogon is thin, and the iodine reaction in the axis is negative. These features are consistent with those of the subgenus Usnea. Within the subge

Eleocharis sphacelata (Cyperaceae) is a common emergent hydrophyte in wetlands throughout Australasia, and is notable as a particularly large member of its genus, able to grow in water up to 2 m deep (Sainty & Jacobs 1981). It is a perennial species, supporting live emergent shoots throughout the year, and grows only on flooded sediments. In Australia, the water temperature in E. sphacelata wetlands remains mild in winter (c. 6°C) but is high (25–30°C) during summer (Brix et al. 1992; Sorrell & Boon 1992).

Quantum flux density under a 15 cm thick layer of snow can reach light saturation for net photosynthesis of Usnea sphacelata at temperatures around 0°C.

Abstract:

Setaria sphacelata es una gramínea forrajera megatérmica cultivada en diversas regiones dada su plasticidad. Al igual que otras forrajeras perennes estivales, tiene lenta implantación. Los tratamientos pregerminativos de hidratación-deshidratación (HD) mejoran la germinación y el establecimiento de muchas especies. El objetivo de este trabajo fue evaluar el efecto de HD con agua y nitrato de potasio en semillas de Setaria sphacelata. Se aplicó un diseño factorial de tratamientos 2 x 3 x 2. Un primer factor fue el agente imbibitorio: agua (A) y nitrato de potasio 2 % (N); el segundo, el tiempo

Abstract:

Successful long-term conservation and management of populations of plants requires successful management of the suite of factors that determine their ‘realised’ mating systems. Within the genus Grevillea, mating systems are potentially complex. They may vary among species and among populations within a species, reflecting variation in pollinator behaviour and diversity (‘potential’ mating systems) and in breeding system (the ‘preferred’ mating system). We used a combination of pollinator observations, pollination experiments and electrophoretic analysis of seed from open pollinations, to exami

Abstract:

Setaria sphacelata is a high and most prevalent tropical grass, while Cleome gynandra is a tropical annual herb which commonly used as vegetables in Africa and Asia. Both plant samples were found to be high in nutritive value especially in protein and very appetizing in ruminants. The main objectives of the study were to measure and compare the nutritional composition of Setaria sphacelata and Cleome gynandra as a function of their nutritional value for ruminants. The two plant samples were collected near the Tembila area, Besut Terengganu. The samples were dried in a furnace below 60 - 70 ˚C

SUMMARYThe intake of temperate forages by herbivores can be determined using the C33 alkane naturally present in the forage and dosed C32 alkane. To determine whether the technique can be used with tropical forages, the concentrations of C33 alkane were determined in seven species.The leaves of Brachiaria decumbens, Digitaria decumbens, Pennisetum glaucum and Stylosanthes scabra contained sufficient C33 alkane (> 50 mg/kg DM) for the estimation of dry matter intake. Low concentrations of C33 alkane were found in the leaves of Setaria sphacelata, Sorghum sp. and Leucaena leucocephala. Setari

A survey of the distribution and abundance of nests of the magpie goose (Anseranas semipalmata Latham) was carried out over 4 years (1980-83 inclusive) at a site covering about 1000 ha on the South Alligator River floodplain at Kapalga, N.T. There were large differences in the number of nests built from year to year. Maximum water depth on the plains and the length of time the plains were flooded varied considerably from year to year and since these factors have an effect on the type and distribution of the vegetation, a study of the relationship between the density of nests, water depth and t
