摘要

摘要/ ABSTRACT摘要:美凌(Veitchia merrilli, Becc)是一种广泛应用于园艺的棕榈树。由于花序上的花是连续生产的,同一株植物上有果实和种子处于不同的成熟阶段,因此很难确定获得健壮种子的最佳果实成熟阶段。本研究通过测定不同成熟阶段果实的生物特征,确定获得生理品质最佳种子的最佳果实成熟阶段。成熟的果实从10棵树的顶端和地面上收获,根据它们的成熟阶段进行分类,并测量总长度、赤道直径和新鲜重量。在温室内进行了5个处理(成熟期)、10个重复的试验,以确定获得生理品质满意的美花栗种子的最佳果实成熟期;每个地块由20颗种子组成。测定株高、根长、茎粗、根上干重、总干重和迪克森品质指数。青果期是获得玉米种子的最佳时期,其生理品质最好。深红色成熟期果实长度最大,绿色过渡期果实直径和鲜重最大。

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.
