Abstract
The objectives of this study were to investigate the effects of successive continuous generation (SCG) cuttings of Buxus sinica var. parvifolia on the rejuvenation of ortets at the hormone level, detect levels of indoleacetic acid (IAA), abscisic acid (ABA), isopentenyladenosine (iPA), zeatin riboside (ZR) and gibberellin4 (GA4) during the rooting process of different generations by means of enzyme-linked immunosorbent assay (ELISA) technology and statistically analyze the rooting characteristics of cuttings. The results show that, the root systems of subsequent generations (generation 1998, 2000) developed satisfactorily, only a few initial generation (generation 1990, 1994) cuttings rooted and the root growth was inhibited. Around the period of callus formation and root projection through the epidermis, there was a marked, regular variation in the levels of IAA, ABA and GA4 between the initial generations and subsequent generations.
