用植物激素对贵州特有、稀有植物──青岩油村种子进行预处理试验，结果表明，以400μg/L的IBA溶液处理种子．出苗率达52.5％比对照高19.5％；用400μg/L的NAA溶液处理种子，一年生苗高12.3cm，地径粗0.19cm，对比照增高4.5cm，增粗0.04cm；2.4-D溶液也可在不同程度上提高种子出苗率及苗木年生长量．
The plant hormones were used to pretreat the seeds of Guizhou rare endemic plant - Qingyan oil seedling. The results showed that the seeds were treated with 400μg / L IBA solution. The emergence rate of 52.5% was 19.5% higher than that of the control. The seedlings were treated with 400μg / L NAA solution, the annual seedling height was 12.3cm, the diameter was 0.19cm, the contrast was increased by 4.5cm and the thickness was 0.04cm. To varying degrees, improve seedling emergence and seedling annual growth.
