Abstract

Buxus sinica var. parvifolia(littleaf box) is one of the woody evergreen plant species that has high commercial value in the floriculture market. Efforts to improve propagation successwill be essential in development of the species for commercial production and in satisfy the markets needs. The purpose of this research is to study the rooting mechanism of Buxus sinica var. parvifolia cutting. Seven cultivars were chosen, including five cultivars of littleleaf box and two of Buxus sinica(Chinese box) to compare the rooting potential. Enzyme-linked immunosorbent assay(ELISA) technology was used to measure the levels of indoleacetic acid(IAA), abscisic acid(ABA), isopentenyladenosine(iPA), and gibberellin4(GA4) in the rooting zones, and the rooting characterswere also observed in spring stem cutting. The results showed that around the time of callus forming and the root projecting epidermis, the levels of IAA, ABA and GA4were different in seven cultivars and in different treatments. And the rooting ability of cultivarNo.3 and No.5 treated byABT6 were improved. The high levels of endogenous hormone in the easy-to-rootcultivars in crucial rooting periodwasbeneficial to callusgeneration and the root anlage formation and differentiation.[Ch, 4 fig. 2 tab. 18 ref.]
