富含紫杉醇良种‘东北红豆杉优良种源’

A Taxol-rich Elite Variety ‘Superior Provenance of Taxus cuspidata’

东北红豆杉优良种源紫杉醇含量高(60.5μg·g-1),比其他种源的紫杉醇含量高出1.5～3倍,生长量与其它种源相同。可以通过播种或扦插方法繁殖。播种前积种需要层积处理,变温层子可以缩短休眠期。扦插繁殖用休眠枝或绿枝。苗期主要管理措施是遮荫、保湿、防寒、防干热风。林下造林成活率较高,生长良好。东北红豆杉优良种源适宜在东北地区空气湿润、pH值小于7.0的沙壤土种植。

There was higher taxol content（60.5 μg·g-1 ） in superior provenance of Taxus cuspidata （ the provenance is Daxinggou ）, which was 1.5 - 3 times than others, and its growth quantity was similar with other provenances. It is planted by sowing or cutting breeding methods. Cording seed was necessary before sowing, and ehangging temperature could shorten period of seed dormancy. Dormant or green branches were made cuttage. Seedling management was shelter from heat or light, keeping soil and air humit, preventing freeze injury and dry wind. There was higher survive rate and growing well if planting seedling under crown. The superior provenance is adaptable to grow in the northeast, and growing better in humit air and acid sandy loam（pH ≤7.0）.
