矮生龙船花(IxoracoccineaL.)的带节茎段在MS+2,4D2.0mg/L培养基上产生大量的愈伤组织;在MS+6BA1.0mg/L+NAA0.2mg/L培养基上芽的增殖系数达413,并产生少量的愈伤组织;在MS+NAA0.2～2.0mg/L培养基上只产生芽而无愈伤组织形成。愈伤组织在MS+6BA0.5mg/L+NAA0.5mg/L培养基上产生大量的不定芽,丛生芽在MS+6BA0.5mg/L+NAA0.5mg/L培养基上生长较快并产生较多分枝,将分枝节下或切成段后在MS+6BA0.5mg/L+NAA0.5mg/L培养基上能迅速生长并产生新的分枝。试管内小苗在1/2MS+NAA0.5mg/L培养基上的生根壮苗效果较好。矮生龙船花试管苗成活率为935%。
The stem segments of Ixoracocinea L. produced a large amount of callus on MS + 2,4D2.0mg / L medium; on MS + 6BA1.0mg / L + NAA0.2mg / L medium Bud multiplication coefficient of 413, and produce a small amount of callus; MS + NAA0.2 ~ 2.0mg / L medium only produce buds without callus formation. Callus produced a large number of adventitious buds on MS + 6BA0.5mg / L + NAA0.5mg / L medium, and the shoots grew faster and produced on MS + 6BA0.5mg / L + NAA0.5mg / L medium More branches, will be sub-section or cut into segments after MS + 6BA0.5mg / L + NAA0.5mg / L medium can rapidly grow and produce new branches. In vitro tube seedlings in 1 / 2MS + NAA0.5mg / L medium on the rooting seedlings better. Dwarf dragon boat flower test tube survival rate of 935%.
