Experiment on Seedling Cultivation by Cutting of Helicia shweliensis

In April 2017, current semi lignification branches from 20-30year Helicia shweliensis were selected for seedling cultivation by cuttings with orthogonal test of 3 levels 3 factors, namely substrate, hormone and concentration. During July 2017 and Feburay 2018, observations were carried out on rooting rate, root length and root number of cuttings. The results showed that different substrates, different hormones and concentrations had evident effect (P<0.05) on rooting rate of cuttings. Cuttings cultivated on the sand, with treatment of 100 mg·L-1 of ABT had the best rooting rate, of 65%. Substrate and hormone type were the main factors for root length of cuttings, Cuttings cultivated on sand, treated by cytokinin had the largest root length, concentration of hormones had no evident effect on root length. Substrate, hormone and concentration had evident effect (P<0.05) on root number. Cuttings cultivated on sand+peat, treated by 100 mg·L-1 of ABT had the largest number of root.
