Potentials of palynotaxa for apicultural entrepreneurships: Implication for conservation and policy

Abstract

The contemporary global economic meltdown has devastating effect on the economy of most rural people in Africa in general and Nigeria in particular. The frantic search for alternative source of national revenue aside from oil and gas has become imperative for economic emancipation of Nigerians. Knowledge of plants foraged by bees for pollen and nectar becomes a panacea to this challenge. This study analysed the pollen spectrum of four honey samples collected from Southern Nigeria in order to determine the richness of the honey plants in the area, and to highlight the potential of these species in apicultural entrepreneurship in Nigeria for green growth economy, using Shannon-Wiener Diversity Index after a standard acetolysis method. A total number of 39 palynotaxa belonging to 21 plant families and distributed in 39 genera were identified. Fabaceae had the highest plant species (11 species), followed by Euphorbiaceae (5 species). The study revealed that Elaeis guineensis Jacq, Anacardium occidentale L. Diospyros mespiliformis Hochist ex ADC, Alchornea cordifolia (Muell)Arg, Daniella oliveri (Rolfe) Hutch & Dalz, Irvingia wombolu Okafor ex Baill, Treculia africana Decne, Nauclea latifolia Smith and Crossopteryx febrifuga Afzil ex Benth, were the dominant honey plants. The palynotaxa spectrum did not vary greatly in the four samples; however, Shannon diversity index was low to moderate (H= 2.7 -3.1). This baseline information has provided opportunity and amazing potentials for apicultural enterprise in these areas. However, most of these honey plants are rare, threatened and endangered. This calls for urgent conservation strategies by all players. Policy programmes could increase production and productivity of hive products through capacity- building for local populace.
