ABSTRACT

 

Article No.: 102420122

Type: Research

 

 

Phenological studies provide information on functional rhythms of plants and plants communities. Timing of various phenological events may reflect biotic and/or abiotic environmental conditions. They are also useful for conservation and management of tree genetic resources because they determine reproductive success of species. This research aimed at studying phenological events in V. paradoxa and their interactions with some environmental factors. Thirty (30) V. paradoxa trees were randomly selected from two distinct locations (densely populated and sparsely populated sites and used in this research. From each selected trees, 8 branches were chosen and from each branch, reproductive phenological events and leaf phenological events were observed and recorded. The data collected were analyzed using Microsoft Excel® and their relationship with climatic conditions was determining using PAST software. Results revealed that V. paradoxa flower from October to March and fruits form March to August. The result also showed variation between the two locations with respect to flowering start dates in which trees in the sparse areas flowered earlier than those in the dense areas; and the flowering synchrony was estimated to 69.2%. Observations showed that V. paradoxa trees shed their leaves from November to March. Furthermore, leaf fall have a positive linear relationship with temperature and wind speed and a negative relationship with relative humidity. The information from this studies will be useful in breeding programmes and management of this important species.
