Ripening of sapodilla fruits (Manilkara zapota [L.] P. Royen) treated with 1-methylcyclopropene after refrigeration
An experiment was conducted during the year 2010 to evaluate the effect of the treatment with 1-methylcyclopropene (1-MCP) on the ripening process of sapodilla fruits, after refrigeration. The fruits were exposed to 0 and 1 µL/L of 1-MCP for 24 h in airtight chambers at 25°C, after which they were stored at 16°C for four periods of refrigeration (0, 11, 18 and 25 days). At the end of each refrigeration...

Species composition, diversity and distribution in a disturbed Takamanda Rainforest, South West, Cameroon
This study assessed the diversity and distribution of trees and shrubs in a 16 ha disturbed plot in the Takamanda Rainforest. Linear transects (8) were laid in the field which radiated from the centre of the plot. The girth of the trees and shrubs were measured and species identified. A total of 99 species (72 trees and 27 shrubs) belonging to 87 genera and 34 families were recorded. Caesalpinaceae was the most...

Effect of salt stress on osmolyte accumulation in two groundnut cultivars (Arachis hypogaea L.) with contrasting salt tolerance
The effects of salt stress on the level of osmolyte accumulation in two different cultivars (K-134 and JL-24) of groundnut seedlings were studied. Seeds were grown at different concentrations of NaCl stress: 50, 100 and 150 mM and their respective controls (0.0% NaCl) for nine days. Salt stress resulted in a significant modification in the level of osmolyte accumulation in the two cultivars of groundnut. The...

The effects of pH and growing medium type on the susceptibility of Moringa oleifera to fungal diseases during seedling emergence
Moringa oleifera seed germinates poorly and most seedlings die during early establishment. To solve this problem, the effects of pH and growing medium type on the susceptibility of M. oleifera to fungal diseases during seed emergence and early seedling establishment were evaluated in a 3 x 6 factorial experiment arranged as a randomized complete block design with three replications in a greenhouse experiment. Six...

Knowledge on cassava disease management: The case of cassava brown streak disease awareness in Northern Uganda
The cassava brown streak disease (CBSD) has spread rapidly in Northern Uganda since its emergence in Uganda in 2005. Field surveys conducted in 2010 and 2011 by Ngetta Zonal Agricultural Research and Development Institute (Ngetta ZARDI) revealed high CBSD prevalence in the zone. CBSD epidemic has severely affected livelihood of smallholder farmers in the region. Lack of knowledge on disease recognition and management...

Pollen morphology of seven wild species of Acacia in Saudi Arabia
Pollen micromorphological characters such as pollen size, shape, number of associated monads, colpi and ornamentation of the tectum surface, of seven species of Acacia belonging to the family Mimosaceae were studied, using light microscope (LM) and scanning electron microscope (SEM). The study showed that the pollen size range from 42.1 to 69.4 µm, pollen shape is round to semi- round, the number of associated...

Petiole anatomy of some species of Asteraceae in southwest Nigeria
Petiole anatomy of 12 species of Asteraceae around Ile-Ife in South-Western Nigeria was described. Transverse section of the petiole (median) was cut at 20 µ using Reichert Sledge Microtome. The specimens were stained in 1% aqueous solution of Safranin O for 5 min, washed in three changes of water to remove excess stain and counterstained in 1% solution of Alcian blue for 5 min, and cleared in xylene. The section...

Effect of intra-row spacing on yield and quality of some onion varieties (Allium cepa L.) at Aksum, Northern Ethiopia
Lack of improved varieties and production practices have been the major bottlenecks of onion production and productivity in Tigray, particularly at Aksum area. There have been no recommended intra-row spacing and variety for that area specifically; rather farmers used to practice non-uniform plant spacing. Thus, a field experiment was conducted to investigate the influence of intra-row spacing, variety and their...
