The South African pulp industry is reliant on Pinus patula as a main constituent of the softwood raw material. However, trees in plantations can periodically be physiologically stressed due to a variety of biotic and abiotic factors. Damaged or dead trees can constitute a loss of pulpwood production to the mill, with the economic consequence of having to source the timber elsewhere on the open ...

There are abundant reports of symbiosis wherein crustaceans live inside or on mollusks; however, there few published records gastropods hosting decapods. This study examines the biological association between fifteen snails (124.86 ± 19.01) from species Pacific crown conch Melongena patula and porcelain crab Euceramus transversilineatus. Morphometric relationships both invertebrates, as well so...

An anaerobic, mesophilic, sporeforming, xylanolytic bacterium was isolated from decayed Pinus patula wood chips. The cells of this organism were gram-negative rods, had peritrichous flagella, and formed terminal round endospores which distended the cell wall. Xylan, cellobiose, fructose, glucose, maltose, mannose, melezitose, raffinose, rhamnose, salicin, sucrose, and xylose were utilized. The ...

The major components patuletin and patulitrin were isolated from French marigold (florets of Tagetes patula). Patuletin and patulitrin were found to inhibit acute inflammation in mice. Oral administration of patuletin and patulitrin significantly suppressed hind-paw edema induced by carrageenin and histamine, while topical application of patuletin and patulitrin significantly inhibited ear edem...

Increasing salinity led to substantially higher ratios of mesophyll surface area to leaf area (A(mes)/A) for Phaseolus vulgaris and Gossypium hirsutum and a smaller increase for Atriplex patula, a salt-tolerant species. The increase in internal surface for CO(2) absorption did not lead to higher CO(2) uptake rates, since the CO(2) resistance expressed on the basis of mesophyll cell wall area (r...

El monitoreo del estado nutrimental de la planta forestal en vivero es crucial para asegurar su calidad y aumentar probabilidad sobrevivencia después trasplante. Actualmente no existen estándares nutrimentales verificar el producción Pinus patula vivero. objetivo presente estudio fue generar curvas abastecimiento un conjunto concentraciones críticas foliares plántula esta especie. Utilizando té...

Macromolecular syntheses in encysted Tetrahymena patula were studied using Feulgen fluorescence cytophotometry, autoradiography, and inhibitors of RNA and protein synthesis. Cycloheximide significantly depressed protein synthesis and D-actinomycin effectively blocked RNA synthesis. Under these conditions, the cells within the cyst were unable to divide. Both cytophotometric measurements and aut...
