Fruit biometry and physiological quality of Veitchia merrilli (Becc) H. E. Moore palm in relation to fruit maturation stage
ABSTRACT Veitchia merrilli (Becc) H. E. Moore is a palm tree widely used in gardening. Due to the continuous production of flowers on the inflorescences, there are fruits and seeds in various stages of maturation on the same plant, making it hard to determine the best fruit maturation stage for obtaining vigorous seeds. This study measured the biometric characteristics of the fruit at different stages of maturation and identified the best fruit maturation stage from which to obtain seeds with optimal physiological quality. Mature fruits were harvested from the tops of 10 trees and the ground, categorized according to their maturation stage and measured for overall length, equatorial diameter, and fresh weight. An experiment to identify the best fruit maturation stage for obtaining seeds of the V. merrilli with satisfactory physiological quality was carried out in a greenhouse, with five treatments (maturation stage) and ten replications; each plot was composed of 20 seeds. Plant height, root length, stem diameter, root and above ground dry weight, total dry weight, and Dickson’s quality index were measured. The green fruit stage is the most suitable for obtaining seeds of V. merrilli with the best physiological qualities. The fruits at the dark red maturity stage had the greatest length, while the those in the green transition stage had the greatest diameter and fresh weight.
