  Abstract:

  Cacao (Theobroma cacao L.) is an important commodity tree crop which produces the cocoa bean, a major source of income for most West African countries and many smallholder farmers. Declining yield of cacao is a major limitation to cocoa production in Nigeria. This study aimed at determining the correlations of the phenotypic traits that were... More

  Abstract: There is no doubt that the chemical composition of plants, including norvolatile and volatile compounds, is widely affected by abiotic and biotic stress. Plants are able to biosynthesize a variety of secondary metabolites against actions of natural enemies, such as herbivores, fungus, virus and bacteria. The present study revealed that the chemical compositions of leaf... More

  Abstract:

  Dwarf Water Lilies (Nymphoides aquatica (J.F. Gmel) Kuntze have floating and submerged leaves. Some submerged aquatic vascular plants have a form of CAM (Crassulacean Acid Metabolism) called Submerged Aquatic Macrophyte (SAM) metabolism. Blue-diode based PAM technology was used to measure the Photosynthetic Oxygen Evolution Rate (POER: 1O₂ ≡ 4e^– ). Optimum Irradiance (E_opt),... More
