摘　　要：在 2 6℃的条件下进行培养 ,去皮处理可显著提高久树种子的发芽率 ,较对照提高 31.7%。ABT4号生根粉在久树育苗试验中 ,可有效地促进久树种子出苗率和成活率 ,浸种浓度在 2 5mg·kg- 1时 ,发芽率、发芽势、平均发芽时间都较对照有明显的提高。F检验证明光照处理的久树种子较遮光处理发芽效果好 。Under the condition of 26 ℃ and decortication, germination quotiety of seeds was improved with 31.7%. Comparing with hindering light. ABT 4 rhizogenesis powder has well applicable future in cultivating seedling of Schleichera oleasa , it effectual promoted the seeds'emerging and remaining quotiety with the thickness of 25 mg·kg -1 , Germination quotiety, germination force and average germination time were markly advanced. By F check, germination index of S.oleasa' s seeds was improved,it proved that the seed is a kind of sensitive seeds to light. Compositive disposal has great advantage to S.oleasa' s seeds, this has great realistically value in lac production.
