Propagation methods of Strawberry

Strawberry is a perennial herb with strong adaptability, short growth cycle, early fruit, quick effect and extensive cultivation. The main ways of reproduction are stolon propagation, ramet propagation, tissue culture propagation and seed propagation. Let's take a look at it.

Strawberry seed propagation

The production efficiency of strawberry seed propagation is low, generally not used, if the family potted growth can try.

Strawberry ramet breeding method

The split propagation of strawberry is also called old plant propagation. This method of propagation is suitable for strawberry nurseries that need to be replaced, or strawberry varieties that are not prone to stolons. The method is to propagate by using the new stem branches produced on the mother plant. During the growing period, the new stem of strawberry can produce not only a large number of stolons, but also several new stem branches, and adventitious roots can occur at the base of the strawberry. After fruit harvest, when the strawberry new stem branches are broken off together with the root system, a complete seedling can be obtained when there are 5 compound leaves and more fibrous roots.

Strawberry stolon propagation

Stolon propagation is the most commonly used method in strawberry production. The seedling from the stolon is called stolon seedling after being separated from the mother plant, which belongs to asexual reproduction, and its propagation method has four advantages.

1. The reproduction coefficient is high. A mother plant can produce 150,290 stolon seedlings, of which root seedlings account for 50% and 80%. Each hectare of strawberries can produce 225000 and 375000 high-quality stolon seedlings a year.

2. It is easy to maintain variety characteristics and fruit quality.

3. It is convenient to collect materials, so we can use the production field to collect seedlings, and we can also set up a mother garden to collect seedlings.

4. the seedlings have strong vitality and bear fruit early. They are planted in autumn of that year and can bear fruit in spring and summer of the following year.

Tissue culture and propagation of strawberry

Strawberry seedlings propagated by traditional methods have some disadvantages, such as slow growth, large land occupation, easy to be attacked by virus, easy to cause degradation, affect yield and fruit quality, and so on. Tissue culture can solve these shortcomings.

1. Fast reproduction: thousands to hundreds of thousands of seedlings can be obtained from a meristem in a year, which has great potential for development.

2. the market variety can be updated quickly: according to the needs of the market, the variety can be updated once in 2-3 years, while it takes 4-5 years for conventional production.

3. Production flexibility: as long as the tissue culture operation workshop is established, that is, the culture laboratory is expanded, it can be produced throughout the year, and the plants can be kept in the cold storage until autumn or the next spring.

4. The proportion of healthy plants is large, and the effect of increasing yield is obvious: the meristem in the stem tip tissue is not poisonous, and the whole operation is carried out in aseptic environment. Compared with the general non-virus-free seedlings, the cultured virus-free seedlings grow faster, the fruit setting rate is higher, the fruiting period is prolonged, the fruit weight is significantly increased, and the average yield can be increased by 30% to 50%.
