紫果云杉在内蒙古地区引种初探
|
摘要
对内蒙古林科院树木园引种的紫果云杉进行观测,研究其生长发育规律及其对环境的适应性。结果表明:紫果云杉生长缓慢,10年以后才能正常越冬,20年以后生长良好;其物候在不同年份存在波动,对冷冻贮存半年的紫果云杉花粉进行测试,其花粉活力可达到79. 8%,可作为优良种质资源培育新种。
Through investigating Picea purpurea planted in Hohhot Arboretum,the growth development and the adaptability to the environment have been studied. The results show that Picea purpurea has a slow growth,which can overwinter normally after 10 years and can grow well after 20 years. There is a fluctuating phenology in different years. The pollen viability of Picea purpurea frozen and stored for half a year can reach up to 79. 8%. It can be used as a good germplasm to cultivate new species.
