Results of storage experiments at a range of moisture contents and temperatures suggest conventional seed bank storage at −18 °C after equilibration at c. 23% relative humidity (at 23 °C) may Previous to the germination tests, the seeds were treated in two different ways: (1) dark storage under dry conditions (nonchilled seeds), and (2) burying in the original soil at cm depth Mycotoxins are secondary metabolites synthesized by filamentous fungi. They are common food contaminants that cause mycotoxicosis in humans and animals. Due to the severity of health risk pose by these mycotoxins, many countries have enacted strict measures to curb this menace. One promising measure is the use of nanoparticles. Herein, we present an overview of the application of titanium Results show that river sediments from the upper catchment exhibit higher total organic carbon (TOC) contents than those from the lower part of the basin.

Under on-farm conditions on severely depleted soils, maize yields increased from to tonnes per ha per year after only 2 years of Sesbania fallow. Further, results have shown that soil physical and chemical conditions are significantly improved in addition to substantial root organic matter input in the B   Although there is a perception that tree seed, especially from tropical trees cannot be stored under conventional seed storage conditions (cold and dry), many valuable tree species for human use in all regions are orthodox in their seed storage behaviour and seed banks to ensure longterm availability of valuable genetic resources are generally   Web view.   Although, cassava is a drought- tolerant crop, growth and yield are decreased by prolonged dry periods. The reduction in storage root yield depends on the duration of the water deficit and is determined by the sensitivity of a particular growth stage of water stress (Connor et al., ; Porto et al., ). Environment and cassava production   The results of this study shows a significant (P) variation in wood density (Afzelia africana>Celtis mildbraedii>Meliceae excelsa>Khaya ivorensis>Triplochiton scleroxylon) The MOR (N/mm2) and MOE (N/mm2) of these wood species indicates that Celtis mildbraedii and Afzelia africana has the highest values (/ and /), Khaya

In addition, Pouteria altissima and Vitellaria paradoxa are found in the Sudanian and Somali-Masai zones and Pterocarpus angolensis in zones II and :// The result of this study showed that the optimum medium for regeneration of K. grandifoliola MS-medium supplemented with mg/L (BAP) + mg/L (NAA) + 10 mg/L adenine sulphate because the values obtained for all the parameter measure was moderately high and optimum. The fact that the number of roots increased to 3 in medium 5 and 7 could be In vitro preservation of the “Kober 5BB” rootstock (Vitis berlandieri × Vitis riparia) was assessed with the encapsulation technique and slow growth storage. Shoot tips and nodal segments excised from in vitro cultures were encapsulated in calcium-alginate beads. A 30 min ion exchange time proved optimal for forming proper beads. The encapsulated and naked explants were stored at 4 °C in
