The latest five factors affecting the expansion of strawberry fruit

Strawberry is one of our favorite fruits, which tastes sour and sweet, has high nutritional value and has a wide range of planting, while many farmers find that their strawberries expand slowly, even unable to expand. The following editor brings you five major factors that affect the expansion of strawberry fruit. Let's take a look.

1. Seeds

Seed plays an important role in the growth and development of strawberry fruit, it is the basis of fruit setting and normal development, fruit growth depends on the regulation of auxin, there is auxin in pollen, auxin needed for fruit growth after pollination, is produced by developing seeds. Therefore, seeds are extremely important for the growth and development of fruits. On the same fruit, some parts of seeds can not continue to grow, while other parts grow normally, then deformed fruits will appear.

2. Nutritional status of plants.

The basis of ensuring fruit size and yield when the plant grows healthily. In the early stage of strawberry flowering, if sufficient assimilation area is not formed, the plant will be undernourished, which will lead to strawberry floral organ dysplasia, short style and low pollen germination rate, affecting pollination and fertilization, resulting in low fruit setting rate and abnormal fruit formation. When the fruit expands, the fruit consumes a lot of nutrients, the vegetative growth of the plant is inhibited, the assimilation ability is reduced, and the synthetic nutrients are watered, which will also affect the fruit expansion, resulting in small fruit and low yield.

3. Temperature

Temperature is closely related to fruit growth and ripening, and the optimum temperature for strawberry growth and development is 18-25 degrees. The lowest temperature is 12 degrees. Buds are most vulnerable to low and high temperatures, and if the temperature is below 0 degrees or higher than 40 degrees, it will only be allowed for pollination and fertilization. For the same variety, in the suitable temperature range, when the daily average temperature is higher, the actual need from flowering to fruit ripening is shorter, the fruit is smaller; the temperature is lower, the actual need is longer, the fruit is larger.

4. Lighting

Strawberry fruit development needs sufficient light, sufficient light, good plant growth, strong photosynthesis, high assimilation efficiency, more carbohydrates transported to fruit trees, rapid fruit expansion, high sugar content and good quality. The more sunny days during the fruit ripening period, the better. If the fruit ripening period meets cloudy and rainy days, then the sugar content and vitamin C content of the fruit will be significantly reduced.

5. Moisture

The water content of strawberry is more than 90%, the water absorption of fruit is picked gradually during fruit development, and the demand for water increases sharply when the fruit is ripe, so the amount of soil moisture has a very important effect on fruit growth and development. The water is sufficient, the fruit expands quickly, the fruit surface is smooth, there is light, the fruit is soft and juicy; when the soil moisture is insufficient, the fruit is small, the fruit surface is withered, and the pericarp is shrunk.
