中文摘要：

采用试验优化设计和计算机分析技术，对西洋参（Panax quinquefolium）和胡萝卜（Daucus carota）2种植物愈伤组织共培养的培养基和培养条件进行了研究。结果表明：在培养基MS＋2，4-D1．67mg／L＋IAA0．98mg／L＋ZT0．47mg／L（蔗糖30g／L，琼脂8g／L）上，西洋参和胡萝卜2种愈伤组织生长率分别达到0．271g／（g·d）和0．137g／（g·d）。适宜的培养条件为（24±1）℃，光照强度1700lx，12h光暗交替。在此培养基和培养条件下，2种植物愈伤组织可以进行共培养。

英文摘要：

The co-culture medium and culture conditions for the callus of American ginseng （Panax quinquefolium ） and carrot（ Daucus carota ） are studied by experiment optimization technology and computer analysis technology. The experiment results show the growth rates of American g/nseng and carrot are 0.271 g/（g·d） and 0.137 g/（g·d） in the medium of MS＋2, 4-D 1.67 mg/L＋ IAA 0.98 mg/L＋ ZT 0.47 mg/L（Pub4）, sucrose 3% ,agar 0.8%. The suitable culture conditions are （24 ＋ 1）℃, illumination intensity 1 700 lx, light dark altemation each 12 h. The two calli can grow well in the same medium and culture conditions.
