Abstract:
Growth regulators(A1,A2) could promote the flower buds differentiation of
Tulipa gesneriana effectively.A1 was better than A2.Through treatment of A1,the rate of flower of
Tulipa gesneriana increased 40%,the length of scape and flower diameter increased 11 cm and 3 cm respectively,the florescence was advanced for 10 d and the flower life was prolonged for 4 d compared with control.Growth regulators(B1,B2) promoted the flower buds differentiation of
Zantedeschia aethiopica significantly and B2 was better than B1.After B2 treatment,the flower rate increased 52%,the length of scape increased 18 cm and the flower diameter increased 1.4 cm compared with control.Meanwhile the abnormality of flower was effectively controlled.Growth regulators(C1,C2) accelerated flower bud differentiation of
Gradlious hybrids,5more flowers were increased for each plant with C2 treatment and the tuber diameter increased 3.8 cm compared with control.
