摘要：塔拉是近年从国外引进的珍贵经济树种，其外种皮十分坚硬、密致，不经处理，种子发芽率仅有１５％。采用９５％浓硫酸处理种子２０～３０ｍｉｎ，保湿催芽３ｄ，使种子发芽率提高到９２％以上，发芽历期从６３ｄ缩短至４～５ｄ，同时摸索出一套科学、简便的实生苗培育技术。
Tara（Caesalpinia spinosa Kuntze）plants are native to south America，mainly distributing in the vallev area in the middle of the eastern Andes and in the seashoredesert along the pacific Ocean. The plant was successfully introducedOthe semiarid valleyin Yunnan in 1991．This paper deals with the technique for breeding Tara seedlings．Theseeds were treated with concentrated sulphuric acid（95％）for 20～30 minutes and kept inwet for 3 days．In this way，the germination percentage was raised from 15 ％ to over92％，and the germinative period shortened from 63 days to 4～5days．The seeds werebreeded in nursery－bags in April；the seedlings reached 24．6～25．7 cm in height and 0．33～0．37 cm in diameter at bottom in July. Measures for controlling seedling pests are alsodiscussed.
