How to plant gypsophila

Gypsophila gypsophila can be cultivated by cutting, grafting and tissue culture methods.

In its cut flower production, tissue culture is mainly used for propagation, which can be carried out year-round. The method is to rinse the picked stem tips with clean water several times and then carry out routine disinfection for later use. The culture medium is MS culture medium with 30 g/L of sucrose and 6 g/L of agar added, and the pH adjusted to 5, 7-6, 0. The culture temperature is (25±2)℃; the light is 12 hours a day; the illumination is 1 to 2 thousand lux. On the culture medium, clustered buds will form after about 4 weeks. Cut them and transfer them to the culture medium for subculture. When adventitious buds grow in large numbers, rooting induction can be carried out. Cut off the tender stems about 2 cm high formed during the subculture process and transfer them to the culture medium to induce rooting. After 4 weeks, most of them will grow new roots about 2 to 3 cm long. When the test tube seedlings are about 3 cm tall and have 4 to 6 new roots about 1 cm long, they are transplanted. The substrate used is vermiculite. When the seedlings grow 3 pairs of new leaves, they can be transplanted. Propagation by cuttings can be carried out every year. Generally, auxin substances are used for treatment. Choose a healthy, disease-free plant with strong growth potential as the mother plant, so the stem tips with 4 to 5 nodes are usually used as cuttings. The cutting substrate used is perlite. The treated cuttings should be soaked in water for 2 hours, then the base of the cuttings should be dipped in 0.1% indolebutyric acid powder for treatment, and then cut at an appropriate distance until the prepared cuttings are ready. On the seedbed, seal the surrounding area with colorless plastic film and do not water during the first week. In the future, spray frequently to moisturize, avoid direct sunlight, and the shading rate should be about 40%. It is best to control the ambient temperature around 20℃.
