Vegetative propagation of Echinops giganteus using stem and root cuttings
Echinops giganteus (Asteraceae) is a shrub native to Cameroon. As part of a recovery effort focused on Echinops giganteus, a vegetative propagation technique was developed. Plants were vegetatively propagated in and out of a non-midst propagator, juvenile stem and root cuttings from the nursery and plant growth regulator hormones of concentrations: 0, 0.5, 1, 2, 3, 4, 5, 8 and 10 g/L. The effect of the cutting positions...
The costunolide biosynthesis enzymes of Artemisia glabella Kar. et Kir.: Determination of the nucleotide sequences of the mRNA
Artemisia glabella Kar. et Kir. is a source of sesquiterpene lactone arglabin, which has antitumor, radiosensitizing and immunomodulatory activity. Studying the biosynthesis of arglabin and its derivatives will allow us to develop the biotechnological basis for its production, thereby increasing its availability. The precursor to most sesquiterpene lactones is costunolide. The purpose of these studies was to detect and...
Salinity resistance strategy of okra (Abelmoschus esculentus L. Moench) cultivars produced in Benin Republic
Salinity negatively influences the physiology and productivity of plants which develop different strategies to resist to this stress. This study aims to evaluate the implication of sodium (Na), potassium (K), proline and soluble sugars accumulation in salt resistance of okra local cultivars after two weeks exposure to 0, 30, 60, 90 and 120 mM NaCl concentrations. Results revealed that the aerial part growth reduction...
