半夏人工种子贮藏技术的研究

目的:研究半夏人工种子的贮藏技术。方法:通过正交实验设计,研究不同浓度的保鲜剂、植物生长物质和防腐剂等因素对半夏人工种子在常温和低温下贮藏后的萌发率影响。结果与结论:以3%海藻酸钠为种皮基质,添加0.1 mg.L^-1GA₃,0.2%苯甲酸钠,1%多菌灵,0.1%Cl₂O以及0.2%壳聚糖制成人工种子,在25℃条件下贮藏30 d后,可获得65%的萌发率。以3%海藻酸钠为种皮基质,添加0.1 mg.L^-1GA₃,0.2%苯甲酸钠,1%多菌灵,0.2%Cl₂O以及0.1%壳聚糖制成人工种子,在4℃条件下贮藏30 d后,可获得80%的萌发率。

Storage technique on artificial seeds of Pinellia ternata

OBJECTIVE: To study the storage technique on artificial seeds of Pinellia ternata. METHOD: Microtubers were used as experiment materials. By using orthogonal experiment, the sodium alginate, added with GA3 badistan, chitosan and sodium benzoate, was used as seed vessel. The artificial seeds were stored respectively under 25 degrees C and 4 degrees C for 30 days, then, calculated the germination rate. RESULT AND CONCLUSION: The sodium alginate(3%) added with GA3(0.1 mg x L(-1)), sodium benzoate(0.2%), badistan(1.0%), ClO2(0.1%) and chitosan(0.2%), were used as artificial seed vessel. Stored under (25 +/- 1) degrees C for 30 days, and the germination rate was over 65%.
