Temperature and Photoperiod Influence Postharvest Needle Abscission of Selected Balsam Fir (Abies balsamea L. (Mill.)) Genotypes by Modulating ABA Levels

Abstract

Seasonal changes in the concentration of abscisic acid (ABA) in current-year needles of two different genotypes (AB-NSD-004 and AB-NSD-184) were monitored in branches collected from 20-year-old balsam fir (Abies balsamea L. (Mill.)) trees over a period of 11 months. A significant genotype × harvesting time interaction was observed for endogenous ABA levels… (More)
