摘　　要：应用^(14)C、^(32)P示踪试验表明,4年生人参青果期喷施胆碱后,其光合速率提高14.22％;^(14)C同化产物转移率增加21.82％,^(14)C同化物在参根总皂甙中的含量(dpm)比对照增加10.66％。胆碱对人参叶面喷施磷的吸收有促进作用,磷的吸收率增加17.81％,根部^(32)P的积累增加31.2％,人参根产量提高28.7％。The results showed that the choline sprayed at green fruit stage of 4 years old ginseng,photosynthetic rate increased by 14.22%,transfer rate of 14C-assi milates increased by 21.82%,amount of 14C-assimilates transported in total ginsensidi of root increased by 10.66% Choline treatment also promoted phosphorus absorption in ginseng,the ratio of 32P absorption increased by 17.81%,and the 32P accumulated in root increased by 31.2%.The yield of ginseng root was increased by 28.78%.
