Salinity tolerance in Phaseolus species during early vegetative growth por Bayuelo Jiménez, Jeannette Sofia, Debouck, Daniel G., Lynch, Jonathan P.

“…Delgado, P. oligospermus Piper, and P. vulgaris L.) and 11 accessions representing five cultivated species (P. acutifolius, P. coccineus L., P. lunatus L., P. polyanthus Greenman, and P. vulgaris) in nutrient solution containing 0 and 180 m M sodium chloride for 21 d. When plants were salinized after the emergence of the first trifoliate leaf, wild accessions of P. acutifolius, P. filiformis, P. lunatus, and P. vulgaris showed a wide range of variation in their salinity tolerance as defined by total dry weight reduction (PR) as a percentage of the unsalinized controls, salt susceptibility index (SSI), and root: shoot ratio (RSR). …”

Saponin rich tropical fruits affect fermentation and methanogenesis in faunated and defaunated rumen fluid por Hess, H.D., Kreuzer, M., Díaz, T.E., Lascano Aguilar, Carlos Eduardo, Carulla, Juan E., Soliva, CR, Machmuller, A

“…A comparison of the effects on rumen fermentation of three saponin rich tropical fruits supplemented to forage-based diets was completed using a rumen simulation technique (Rusitec). The diets contained either no tropical fruit or 100?mg/g of Sapindus saponaria (crude saponins, 120?…”

Sequential phosphorus extraction of a 33P-labeled oxisol under contrasting agricultural systems por Buehler, S., Oberson, Astrid, Rao, Idupulapati M., Friesen, Dennis K., Frossard, Emmanuel

“…The organic or recalcitrant inorganic fractions contained almost no exchangeable P. In contrast, in soils with low or no P fertilization, more than 14% of the 33P was recovered in NaOH-Po and HCl-Po fractions 2 wk after labeling, showing that organic P dynamics are important when soil Pi reserves are limited.…”
