- Abstract:
-
In order to improve the survival rate, the effect of naphthylacetic acid(NAA) on cuttage propagation of Wedelia Trilobata Hitchc was studied based on the basal part of cutting Wedelia Trilobata Hitchc soaked for 1 h with different concentrations of NAA(100 mg/L, 200 mg/L and 300 mg/L). The results showed that the rooting rate treated with 200 mg/L NAA was 100%. At the same time, root diameter, root number, length of the longest root and total volume of root system increased significantly,the aboveground part of Wedelia Trilobata Hitchc showed increasing trend. 100 mg/L NAA improved the aboveground part and underground part of the cuttage. 300 mg/L NAA improved the aboveground part of the cuttage, however, it inhibited the rooting rate and root number of the cuttage. In brief, the facilitation for growth of cuttage seedling treated with 200 mg/L NAA was the best.
