ABSTRACT: In order to realize the efficient industrial
production of Ilex “China Girl”, an
orthogonal experiment with 4 factors and 3 levels was designed. Firstly, the
optimal orthogonal cutting scheme was selected from 9 treatments. Then through
the systematic analysis of the effects of cutting position, substrate,
exogenous hormones type and concentration on rooting indexes, such as rooting
rate, root number, root length and root effect index, the theoretical optimal
scheme was predicted and verified. The results showed that the theoretical
optimal scheme (3000 mg/L IBA treatment for 15 s, cutting in mixed matrix with
peat soil, perlite and vermiculite ratio of 2:1:1) was the optimal cutting rooting scheme of Ilex “China Girl”. After the treatment of this scheme, the
rooting rate of Ilex “China Girl” reached
100%, the average root number was 51.67 per plant, and the average root length
was 6.13 cm. The rooting time was greatly shortened, the rooting rate and
rooting effect were greatly improved. In this study, the efficient cutting
propagation technology system of Ilex “China Girl” was established, which laid a foundation for the popularization
and application of Ilex “China Girl”,
and also provided reference for further improving the cutting propagation
efficiency of other evergreen holly. This study laid a foundation for the
application of Ilex “China Girl”, and
also provided a reference for further improving the cutting propagation
efficiency of other evergreen holly.
