EFFECT OF DIFFERENT LIGHT INTENSITIES ON THE GERMINATION AND EARLY GROWTH OF CHRYSOPHYLLUM ALBIDUM SEEDLINGS
ABSTRACT
The current study looked at how varying light intensities affected the germination of Chrysophyllum albidum seeds and the species’ early seedling development. The treatments tested included 100%, 60%, and 40% light intensities under forest canopy (control I) and open nursery conditions (control II).
The seedling growth characteristics studied were height, collar diameter, number of leaves, and biomass output. The experiment, which lasted roughly 18 months, was carried out at the departmental nursery of the Department of Forestry and Wood Technology at the Federal University of Technology Akure in Ondo, Nigeria.
The results showed that light intensity had a substantial effect on seed germination and seedling growth rate. Cumulative germination ranged from 19.0% to 58.7%, with the highest rates occurring under forest canopy and the lowest under 100% light intensity.
Seedlings in a high light environment (100% light intensity and open nursery conditions) died soon after germination, demonstrating that prolonged exposure to light has a negative impact on the growth of C. albidum seeds.
The seedlings developed best in low light environments with light levels of 40% and 60%. Except for collar diameter, 40% and 60% showed comparable effects on all of the growth characteristics evaluated in this study.
Seedlings grown under 40% light intensity had significantly larger collar diameters than those grown under 60% light intensity. Seedlings under the forest canopy showed low growth germination, implying that C. albidum seedlings may not withstand high shade environments for optimal growth.
Despite having a slower development rate than certain forest fruit tree species, Chrysophyllum albidum saplings can endure low light intensity.
