摘要
香荚兰是生长在热带地区的攀援性兰科植物。原产墨西哥,现广泛栽植在热带多雨地区。它的果实(荚)发酵后,是一种天然食品香料(主香成份是香草醛)的来源。 香荚兰可以用种子繁殖,但从出芽到结实约需7—9年。因此,通常用扦插法繁殖。用长为30—50厘米的插条扦插,3—4年后即可开花结实。因所用的插条较长。
Lateral buds of Vanilla planifolia were used as explants and cultured on MS (or VW) medium supplemented with IAA (0.1-0.5 mg/1) and 6-BA (1.0-2.0 mg/1). Subcultures were made every 6- 8 weeks. Multiplication ratio is 3. Test-tube plantlets, longer than 10 cm, were obtained by transfering the well grown shoots in the medium without 6-BA. In Jinghong, after planting the plantlets in the field, in 31 months, some of the plantlets bloomed.
