How to propagate Anthurium? A detailed guide to common propagation methods
Anthurium propagation includes division, seed sowing, tissue culture and so on. At present, seeds are mainly obtained through sexual hybridization to cultivate superior plants, but since Anthurium is a cross-pollinated plant, the progeny of highly heterozygous hybrid seeds will show extensive trait segregation and great variation. Let's take a look below!
Seed propagation of Anthurium
In breeding, sowing seeds is the main way to obtain new Anthurium varieties. The Anthurium fruit is a berry, and it must be sown immediately after harvesting. Before sowing, remove the fruit skin and wash off the flesh to avoid the skin and flesh rotting and becoming moldy, which would affect the seed germination rate. The sowing method can use the pure sand germination method: sow the seeds individually in clean river sand at a sowing depth of 0.5-0.8 cm, maintain a certain humidity, and generally they will germinate in about 15 days, with new leaves soon growing out. When they grow to 5-6 leaves, they can be transplanted into a substrate of pure perlite mixed with peat soil or coconut coir at a ratio of 1:2 for temporary planting cultivation.
Division propagation of Anthurium
For division propagation, it is best to choose the cool spring and autumn. When dividing, be careful not to damage the mother plant. Side shoots that are too large are not divided, side shoots that are too close together are not divided, and side shoots that are too weak and small are also not divided. Choose side shoots that are relatively easy to separate from the mother plant and relatively robust, with at least 2 or more main root systems.
Cutting propagation of Anthurium
Cutting propagation of Anthurium involves cutting off old branches, removing the leaves, and taking every 1-2 nodes as a cutting, then inserting them into a cutting bed at 25-35°C; after a few weeks they can sprout and take root.
Tissue culture of Anthurium
Tissue culture is the process of placing Anthurium callus tissue and leaves into a culture medium for cultivation. Generally, leaf tissue culture is used, as leaves are easy to disinfect and the operation is relatively convenient. During the bottle seedling stage, tissue-cultured seedlings complete their growth process under various optimal growth conditions provided artificially. Therefore, tissue-cultured seedlings must undergo a process of adapting to the external environment.
