Abstract:

Different kinds of phytohormones, phytohormone concentrations, different substrates, thickness of scion s and water-soaking treatment were used to study the best cutting effect of E. bockii. Diels. The effects of different treatments on the rooting rate, rooting number and root length were evaluated by statistical analysis. The results showed that the best effect on E. bockii. Diels cutting was from the leaf mould, the rooting rate, rooting number and root length were 77.3%, 3.8 and 4.1 cm. For the hormone treatments, the best effects was obtained by treating with IBA 150 mg/L. the rooting rate, rooting number and root length were 78.1%, 3.9 and 3.7 cm. But for the cutting diameter, the cutting diameter with 5-6 mm was the effective way. The best combination was follows: diameter 5-6 mm cutting treated for 4 hours with ABT7 150 mg/L and planted in the cutting medium of leaf mould. The water-soaking treatment for 3-5 days had the best effect for rooting.
