Abstract

Taxus chinensis var. mairei is a unique Chinese species designated as a national level key protected plant. In this research, for the first time, ex-situ conservation and cultivation techniques in a series of trials with direct seeding, cuttings, transplants, and colonization were conducted in December, 1999 with T. chinensis var. mairei on Zhoushan Archipelago. Results showed that seedling growth had an annual average height of 18.9 cm and base diameter 0.32 cm, while with certain technical measures maximum height was 35.0 cm and base diameter was 0.50 cm. With intermittent spray in a canopy covered with shading nets, five-year-old seedlings from cuttings and direct seeding achieved a rooting rate of 90%; however, using ABT 1 rooting powder (a high efficiency plant growth regulator), it was possible to attain 100% rooting. Propagation of transplanted container seedlings in a greenhouse also achieved favorable results. In steady-wind-speed region with a thick soil layer, six-year-old saplings reached an average height of 2.30 m and base diameter of 5.42 cm with an average diameter at breast height of 2.37 cm; the average crown width from east to west reached 2.42 m and from south to north 2.15 m.
