A note on the formation of compression wood induced by morphactin IT 3456 in Thuja shoots

Abstract

1,ight and scanning electron microscopcs were nsed to examine the struetnre of normal wood, naturally formed compression wood, and wood fornled after and influenced by morphactin IT 3456 trcatlnent in Thuja occidentalis L. lateral shoots.Morphactin strongly induced typical compression wood formation around those shoots.On the basis of these and prior data, a relationship apparently cxists hetween morphactin treatment and the formation of colnpression wood in Coniferales.
