Last Updated: 2024/11/05, Carnation can be propagated by sowing and tissue culture: ① sowing and propagation. First of all, the healthy and disease-free plant should be selected as the seed mother plant. When the capsule changes from green to light yellow, it is harvested, dried, and the seeds are scattered out, remove impurities and store them in a dry and ventilated place. In the Yangtze River valley in the south, most of the seeds are sown in March, and after the seeds are germinated and unearthed, the seedlings must be carried out to enlarge the gap between the seedlings in order to ventilate and penetrate the light, so that they can grow healthily; they can also be sowed on the cultivation seedling bed directly according to the row spacing of 20cm × 40cm, for maintenance and management. Sown during this period

Carnation can be propagated by sowing and tissue culture:

1. Sowing and breeding. First of all, healthy plants without diseases should be selected as seed mother plants. When the capsules change from green to light yellow, they should be harvested, dried, and the seeds scattered. After impurities are removed, they should be stored in dry and ventilated places. In the Yangtze River basin in the south, sowing is mostly done in March. After germination and emergence of seeds, seedlings must be thinned, and the gap between seedlings must be increased so as to ventilate and transmit light to make them grow strong; it can also be directly planted on the seedling bed according to the row spacing of 20 cm ×40 cm for maintenance and management. The seeds planted during this period mostly bloom in May to June.

② Tissue culture propagation. Because the seedlings cultivated in test tubes have thin stems and few roots, they must be cultivated in pearlite and other soil seedling beds for a period of time to make them a complete and healthy seedling before they can be planted in the nursery. Although this method requires large investment and high technical requirements, the seedling quality is better.
