我国半乳甘露聚糖胶资源利用前景初探

半乳甘露聚糖植物胶加工是我国70年代中期兴起的新兴产业。本文从我国植物资源发展的角度。重点论证了瓜尔豆（Cyanopsis tetragonoloba（L.）Taubert.）、田菁（Sesbania cannabina(Retz.)Pers.)、胡芦巴（Trigonella foenum-graecum L.）的生产情况,认为胡芦巴适应性强、产量高、易于机械化大面积种植与轮作,并具有改良土壤以及经济效益好等优势。因此,发展半乳甘露聚糖胶资源,大量种植胡芦巴是最好的选择。     

In vitro plant regeneration from cotyledon explants of Swainsona salsula Taubert

An effective protocol has been developed for plant regeneration from cotyledon explants of Swainsona salsula Taubert (Saline swainsona), a medicinal and agronomic shrub. Adventitious shoots were obtained from 83.2% of cotyledon explants from 3-day seedlings cultured on Murashige and Skoog (MS) medium containing 2.0 mg l⁻¹ thidiazuron (TDZ), with an average of 9.3 shoots per explant. Individual elongated shoots were rooted on half strength MS medium supplemented with 2.0 mg l⁻¹ indole-3-butyric acid (IBA), with 59.3% success. Regenerated plants with well developed shoots and roots were successfully transferred to soil, without detectable variants. Histological observation revealed that shoots developed from cotyledon explants via organogenesis, with little callus. This revised version was published online in June 2006 with corrections to the Cover Date.
