Cutting Propagation of Pelargonium

Family cutting propagation of geranium, because of its dry stem fleshy, contains more water, so there is often the phenomenon of decay, affecting survival. For this reason, the author makes some improvements in practice combined with re-cutting after flowering, so that when the cuttings are cut, the survival rate will be significantly improved. The specific practices are as follows:

Select sturdy branches, every 4 to 6 leaves from the stem tip down, or measure about 7 cm to 10 cm in length until the height of the plant is routinely re-cut after flowering, and several cuttings are designed in advance. Then, 0.5 cm below the stem node, carefully cut or peel off the cortex with scissors, ranging from 0.2 cm to 0.4 cm wide, so that the branches can still stand upright as usual. If such a branch is not separated from the plant, it can form 2 to 4 living cuttings to be cut. After that, according to the routine management for 2 to 3 weeks, the annular wound was naturally dried and healed, then the cuttings were cut off, and then the cuttings were placed in a cool and ventilated place to dry for several hours. when the cuttings section dried conjunctiva, the cuttings were inserted into the basin where the culture soil was prepared beforehand. Pour enough water after insertion, it will be dry and wet later, and it can take root after 3 weeks.

The author believes that the annular cutting and peeling layer in vitro directly reduces the wound area of the cutting section on the one hand, and the most important thing on the other hand is to block the flow of photosynthates in the leaves, resulting in the accumulation of nutrients on the plant at the base of the cuttings. these nutrient accumulation plays an important role in avoiding wound infection and promoting the formation of healthy callus and rapid rooting.
