Study on Cutting Propagation Technology with Full Illumination Spray of Superior Clones of Magnolia officinalis Subsp. biloba

Abstract:

In order to improve the survival rate of cutting propagation of Magnolia officinalis subsp. biloba (Rehd,et Wils.) Law. and speed up the application of its superior clones, the research studied on cutting experiment of the superior clones. The semi-wood branches were processed with different types of hormones, different concentrations, different soaking time and different mediums. Through singer-factor experiments，better impact factors were selected in the research, then designing orthogonal test, in order to obtain the optimum cutting formula. The results showed that: immersed in the solution of KIBA with concentration of 1000 mg•L-1 for 30min, in late August or early September, with the medium of peat soil: perlite: yellow sand (1:1:1) was the best formula, and the rooting rate was up to 94.4% in 90d.
