Journal Article 1994

Autor: Ekanayake, I.J. Ortiz, R. Vuylsteke, D.R.

Leaf age effects on the leaf conductance to water vapour diffusion of the adaxial and abaxial leaf surfaces were measured in the morning and in the afternoon on 17 different plantain and banana (Musa spp.) genotypes. The irradiance levels increased three-fold while leaf to air vapour pressure def...

Cultivated plantains and bananas (Musa spp.) are important staple crops in the humid forest and midaltitude ecologies of sub-Saharan Africa. Their water requirement is relatively high and they are very sensitive to dry soil conditions, which greatly limits their range of cultivation. While long-t...

The distribution of the cyanogenic potential in cassava germplasm has been found to be a continuum from very low values to high levels. Within the same genotype, the cyanogenic potential is affected by the planting season; it is low when planted at the beginning of the rainy season, and high when...

An extensively distributed root system may reduce the probability of crop failure during periods of restricted water supply . A quantitative measure of root distribution in the soil profile, i .e . pulling resistance of roots (PR), was tested at two moderately droughted tropical field sites . A t...

Leaf resistances of 14 cultivated potato genotypes ( Solanum spp.) and three tuber-bearing wild Solanum species were compared when plants were grown under water stress at two tropical sites. Factors investigated were diurnal changes in leaf resistance, the effect of plant age, transient drought v...

Flower initiation in some plant species is associated with the physical and chemical soil characteristics such as the availability of certain mineral elements and soil moisture status. The objective of this study was to examine the effects of soil physicochemical traits on the differential flower...

Twelve cassava genotypes were evaluated in the field in two cropping seasons at two locations in Nigeria for their reaction to cassava mosaic disease (CMD), cassava bacterial blight (CBB) and cassava green mite (CGM), using visual injury scores as the index for resistance. Lowest indices for CMD ...

Twelve cassava (Manihot esculenta crantz) genotypes were grown at two field sites in Nigeria representing lowland and mid-altitude agroecological zones from 1994 to 1996 (Ibadan and Jos). Leaf area development and dry matter partitioning were studied by the destructive growth analyses at 3, 6, 9,...
