Can strawberries be grown in the tropics? What is the temperature requirement?

Strawberry has strong adaptability to temperature and likes warm climate, but it is not resistant to high temperature and has certain cold tolerance. In early spring, when the local temperature reached 2℃, the roots began to move, and new roots appeared at 10℃. The optimum temperature for root growth is 15 ~ 20℃. When the soil temperature drops to -8℃ in winter, the root system will be damaged. When the temperature is 5℃, the aboveground parts begin to grow. When the temperature drops to-1℃, plants will be frozen. In case of flowering, the pistil will be frozen and the flower heart will turn black. The optimum temperature of strawberry seedling growth is 18 ~ 23℃, and the optimum temperature of photosynthesis is 15 ~ 25℃, and the growth is inhibited when the temperature exceeds 30℃ in summer. The optimum temperature for pollen germination is 25 ~ 27℃. When the flowering period is lower than 0℃ or higher than 40℃, it will hinder pollination, affect seed development and lead to deformed fruit. Daytime temperature 18 ~ 20℃ is the optimum temperature for fruit expansion. During the day, the temperature is higher to promote the fruit coloring and ripening, but the fruit is small and the harvest time is early. In the range of 17 ~ 30℃, the accumulated temperature reaches about 600℃, and the color can be matured. It takes 30 days to mature at an average temperature of 20℃ and only 20 days at 30℃. The cold resistance of strawberry seedlings is greatly improved after late autumn frost and low temperature exercise, and the buds can withstand the low temperature of-10 ~- 15℃.
