Tomato growth cycle

The growth cycle of tomato is 110-170 days. Development period: generally 7-9 days; seedlings generally need about 50 days at suitable temperature, 60-80 days in cold season and 40 days in high temperature season; flowering and fruiting period: this period takes 15-30 days, early ripening or high-temperature cultivation takes a short time, and vice versa; tomato fruit begins to expand 3-4 days after flowering and pollination, the fastest is 7-20 days, it expands to the limit after 30 days, and begins to color in 40-50 days to reach maturity.

The period from seed sowing, germination to seed ripening of the first ear is the growth and development cycle. It can be divided into four stages: germination stage, seedling stage, flowering and fruiting stage.

I. germination period

The period from seed germination to the emergence of the first true leaf from two cotyledons is the development period, usually 7-9 days.

II. Seedling stage

The period from the appearance of the first true leaf to the appearance of large buds is the seedling stage. it generally takes about 50 days for seedlings at suitable temperature, 80 days in cold season and 40 days in high temperature season.

3. Flowering and fruiting period

During this period, it takes 30 days for 15 murmurs, and it takes a short time for precocious or high temperature cultivation, and vice versa.

IV. Fruiting period

The fruit of tomato began to expand 3-4 days after flowering and pollination, the fastest in 7-20 days, reached the limit after 30 days, began to color in 40-50 days, and reached maturity.
