Study on Cutting Propagation of Toona ciliata Clones.

Cutting propagation rhizogenesis of Toona ciliata clone cutting orchard were studied, and the results were as follows: Rooting type included both callus rooting and cortex rooting. About 17 in 22 of clones were dominated by cortex rooting, accounting for the 77% of clones. There were 5 clones which occurred with both callus rooting and cortex rooting during rooting process. The rooting efficiency index (REI) showed a positive correlation with the rooting rate. Under natural temperature condition, keeping moisture and shading, we found that the highest survival rate occurred in early June, September, and October. [ABSTRACT FROM AUTHOR]
