This paper presents validation results and some management applications of a Tropical Pasture Simulator. The e€ects of di€erent environmental conditions, N fertilisation regimes and grazing intensities are analysed, and physiological concepts are used to aid in the interpretation of the responses obtained. The model demonstrates the importance of ̄exible management guidelines depending on envir...

Green Revolution technologies were developed and promoted to boost food supplies and foster development, both of which were expected to create "breathing space" for achieving demographic transitions in developing countries through lowered human fertility. Little comprehensive research, however, has been done on the effects of those technologies themselves on human fertility -leaving unanswered ...

A finely dispersed cell suspension was obtained from embryogenic calli of two genotypes of pearl millet (Pennisetum americanum L. Mil cereal). Protoplasts isolated from both cell suspensions divided and produced globular embryoids and calli. On an agar medium, the embryoids were induced to form albino shoots or albino plantlet- like structures

Apomixis is a naturally occurring mode of asexual reproduction in flowering plants that results in seed formation without the involvement of meiosis or fertilization of the egg. Seeds formed on an apomictic plant contain offspring genetically identical to the maternal plant. Apomixis has significant potential for preserving hybrid vigor from one generation to the next in highly productive crop ...

Completed genome sequences provide templates for the design of genome analysis tools in orphan species lacking sequence information. To demonstrate this principle, we designed 384 PCR primer pairs to conserved exonic regions flanking introns, using Sorghum/Pennisetum expressed sequence tag alignments to the Oryza genome. Conserved-intron scanning primers (CISPs) amplified single-copy loci at 37...

Because of a complex chemical ultra-structure of lignocellulosic biomass, pretreatment is a necessary step for its conversion into bio-ethanol. In the present study, pretreatment conditions using the ionic liquid (IL) 1-allyl-3methylimidazolium chloride ([Amim]Cl) were optimized for a relatively new model energy crop, hybrid Pennisetum (P. americanum × P. purpureum) to maximize the yield of fer...
