Response of tomato (Solanum lycopersicon) to cadmium toxicity: Growth, element uptake, chlorophyll content and photosynthesis rate

The effect of cadmium (Cd) accumulation on mineral composition in roots and shoots, growth development, chlorophyll and water content of tomato (Solanum lycopersiconMill 63/5F1) seedlings was tested under doses of 0 (control), 10, 50 and 100 µM. Cadmium accumulation was defined by elevated concentrations as 50 to 100 µM in root and shoot tissues. Element uptake by roots and shoot was negatively affected...

Vegetation and flora dynamic of the fallow of the national centre of floristic (NCF) of Cocody-Abidjan University (Ivory Coast)

The flora and the vegetation of the fallow of the National Centre of Floristic (NCF) were analyzed 14 years after first inventory was carried out in 1995. The objective of this study was to evaluate the evolution of the flora and the vegetation of the fallow of the NCF. Thus, the fallow was divided into 4 layers representing each one with homogeneous plot. The methodology of inventory adopted is the combination of the...

Foliar micromorphology of Salvia greggii A. Gray (Lamiaceae)

Foliar micromorphology of Salvia greggii A. Gray was investigated using the scanning electron microscope (SEM). The leaves were characterized by anisocytic stomata which were more abundant on the abaxial epidermal surface. Short multicellular glandular trichomes were observed on both leaf surfaces. Uniseriate and multicelullar non glandular trichomes were also found but more abundant over the mid-rib....

Pollen morphology of Tacca leontopetaloides (L.) Kuntze in Nigeria

The pollen of Tacca leontopetaloides collected from four different locations across Nigeria was prepared and studied under the light microscope. The exine pattern was observed to be fairly striate in all samples from the four different locations, while all the grains were monosulcate. Based on the polar axis size, the pollen sample from Akoko (sample A) was small sized, while the rest are medium sized. The...
