Study on Leaf Cutting Propagation of Two Kinds of Gesneriaceae Based on Orthogonal Test
Northern Horticulture 2021.(02): 65-72,79
ABSTRACT
In order to provide reference for the cutting propagation technology of Primulina, the factors influencing the cutting survival of Primulia were discussed. With Primulina dryas ‘Hisako’ and Primulina‘Blue Mood’ as materials, orthogonal experiment design was used to study. Three factors and three levels test were carried out on Primulina dryas ‘Hisako’ and four factors and three levels test were carried out on Primulina‘Blue Mood’. The effects of different factors and matrix components on the survival rate, number of new plants and leaves of new plants were analyzed, and the best combination was selected. The results showed that the influence of three different factors on the survival rate of Primulinadryas ‘Hisako’ was concentration﹥substrate﹥leaf position, the influence on the number of new plant was leaf position﹥concentration﹥substrate, the influence on the number of new plant’s leaves was substrate﹥leaf position﹥concentration, the optimal combination was IBA+NAAequal mixed concentration of
100mg·L-1+peat:perlite:vermiculite volume ratio of 2:1:1+lower part of leaf, The effect of the four substrate components on the survival rate of Primulina‘Blue Mood’ was peat﹥rice husk charcoal﹥vermiculite﹥perlite, the effect on the number of new plant was perlite﹥peat﹥vermiculite﹥rice husk charcoal, the effect on the number of leaves were peat﹥rice husk charcoal﹥perlite﹥vermiculite, the optimal combination of cutting substrate was peat, perlite, vermiculite, rice husk charcoal volume ratio of 6:2:2:1.
