The exploitation of yellow flower tea in the wild is massively, causing yellow flower tea to be in danger of being eradicated. Therefore, there is e need for researching on the propagation to preserve precious genetic resources. The experiment was conducted to compare the effects of plant growth regulators on the ability to propagate by cuttings of Yellow flower tea in Yen Bai province. The results showed that formula 2 (IBA 100 ppm) gave the growth target was the best, the survival rate after 120 days reached 73.3%, the average of rooting rate was 60%, the average number of roots per cut was 4.6
the average of root length was 9.3 cm
the rooting index was 42.8%
The average leaf area was 67 cm2 and the ratio of seeding with planting standards was 71.1%.
