Propagation and conservation of endangered Magnolia kachirachirai in Taiwan .

Magnolia kachirachirai is carry-over plant under ice age. Its rarity, has long been endangered records. Often located in the southern mountain ridge of Taiwan area, elevation from 400 m-1800 m. A small number of trees with an annual production capacity of seed germination. In particular, when the seed is not a good harvest years, they increase the difficulty of seed collection. After a preliminary germination test, confirmed Magnolia kachirachirai seeds belonging to exhibit recalcitrant storage behavior. Just take them to instantly sowing the seeds of the way, that is, within three weeks in 89% of germination rate. Through the use of cutting propagation after 6 months, media control to an appropriate humidity and a minimum of pollution. Will enable the NAA 2000 ppm and 3000 ppm-treated rooted. To graft, even if their own as a scion and rootstock, it is 100% death, therefore vegetative propagation grafting is the most unfeasible method. Use of air laying method, NAA 2000 and 3000 ppm concentration treated , can be made rooting, the first began on the 1.5 months, NAA 3000 ppm can be achieved the largest root.
