Study on the Cutting Propagation of Lonicera cuminata and Lonicera macranthoides

Abstract

With the branches of Lonicera cuminata and Lonicera macranthoides used as materials, the rooting effects of the cutting season, plant growth regulators and their concentrations and processing time on stem cuttings are investigated. The factors mentioned above the rooting effects of stem cuttings form cutting Lonicera cuminata in spring and autumn are better than from that of Lonicera macranthoides. In spring, cutting propagation the annual hardwood of Lonicera cuminata and Lonicera macranthoides, best result is 200 mg/L ABT No.1 to 2 h, with Lonicera cuminata rooting rate and average root length being 85.6% ∼ 98.00%, 17.9 ∼ 22.6 mm. Lonicera macranthoides rooting rate and average root length were 69.7% and 10.3 mm. In Autumn, cutting propagation the biannual hardwood of Lonicera cuminata and Lonicera macranthoides, best result is 100 mg/L ABT No.1.with 2 ∼ 4 processing hours.
