Five factors affecting the expansion of strawberry fruit

Strawberry is one of our favorite fruits. It tastes sour and sweet, has high nutritional value and is planted in a wide range. Many farmers find that their strawberries expand slowly or even cannot expand. The following small series brings you five factors that affect strawberry fruit expansion. Let's take a look together.

1. Seeds

Seed plays an important role in the growth and development of strawberry fruit. It is the basis of fruit setting and normal fruit development. Fruit growth depends on the regulation of auxin. Auxin exists in pollen. Auxin required 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 seed parts cannot continue to grow, while other parts grow normally, then abnormal fruits will appear.

2. Plant nutrition status

When the plant grows healthy, it ensures the fruit size and yield. In the early flowering stage of strawberry, if sufficient assimilation area cannot be formed, the nutrition in the plant will be insufficient, which will lead to poor development of strawberry flower organ, short style and low pollen germination rate, which will affect pollination and fertilization, resulting in low fruit setting rate and abnormal fruit formation. During fruit expansion, the fruit will consume a large amount of nutrients, plant growth is inhibited, assimilation ability is reduced, synthetic nutrients watering will also affect fruit expansion, resulting in small fruit, low yield.

3. Temperature

Temperature and fruit growth and maturity are closely related, strawberry growth and development of the appropriate temperature for 18-25 degrees. The lowest temperature is 12 degrees. Buds are most susceptible to low and high temperatures, allowing only pollination and fertilization if the temperature is below zero or above 40 degrees. For the same variety, in the suitable temperature range, the higher the daily average temperature, the shorter the actual time required from flowering to fruit maturity, and the smaller the fruit; the lower the temperature, the longer the actual time required, and the larger the fruit.

4. Light

Strawberry fruit development needs sufficient light, sufficient light, good plant growth, strong photosynthesis, high assimilation efficiency, more carbohydrates than fruit trees, rapid fruit expansion, high sugar content, good quality. The more sunny days the fruit ripeness, the better. If the fruit ripeness meets rainy days, the sugar content and vitamin C content of the fruit will also decrease significantly.

5. Water

Strawberry water content of more than 90%, fruit development period water absorption gradually pick, fruit a large number of mature, the demand for water sharply, so the amount of soil moisture on fruit growth and development has a very important impact. Water is sufficient, fruit expands quickly, fruit surface is smooth, there is light, fruit is soft and juicy; when soil moisture is insufficient, fruit is small, fruit surface shrivels, pericarp shrinks.
