摘　　要：研究了大花蕙兰原球茎诱导技术，快繁增殖技术，同步化发育技术以及生根苗假植技术。结果表明：①适当浓度的6-BA使各参试品种都能产生原球茎，3个品种平均诱导率约为64％，其中1#、2#、3#品种的最佳诱导率分别为80％、47％、64％。②较低浓度6-BA与较低浓度的NAA配合，可使各参试品种原球茎30天的平均增殖率达到4—5倍，个别增殖达10倍以上。③通过综合调控可以使90％以上的原球茎按照期望的方向同步发育。In this paper,we studied the propagation techniques of cymbidium grandiflorium on inducing protoeorm-like bodies （PLBs） ; high - speed propagation of PLBs ; development homogenization of PLBs and false plant of rooting seedling. The results showed that ： （ i ） PLBs were normally formed by suitable concentration 6-BA,and average inducing ratio of three varietys was 64 % ,the best inducing ratio of 1#, 2 # and 3# variety were respectively 80 % ,47 % and 64 % ; （ii） As concentration of 6-BA and NAA in medium was lower zamely ,the all experimental variety average propagation ratio of PLBs can arrived 4 -5 times or 10 times in 30 days ; （iii） More than 90 % PLBs can synchronize as required development orientation by synthetical step of adjustment and control.
