The growth and development process of radish can be divided into: vegetative growth stage, seedling stage, fleshy root growth stage and reproductive growth stage.

1. Vegetative growth period: The germination period is from the germination of the seed to the expansion of the two cotyledons. It relies on the nutrients stored inside the seed to cause it to germinate. The cotyledons are unearthed, which requires sufficient water and suitable temperature.

2. Seedling stage: The first true leaf of the seedling unfolds into the seedling stage, which requires higher temperature and stronger light for the seedling to fully develop.

3. The fleshy root growth period: From the time when the fleshy roots are broken to the time of harvest, the fleshy roots are in the growth period. During this period, the fleshy roots undergo secondary growth, and the intercellular spaces are also continuously increasing, forming lateral growth, so the fleshy roots are The roots gradually become thicker from the slender shape in the seedling stage, showing the characteristics of the variety.

4. Reproductive growth period: Radish is a biennial vegetable. It passes through the vernalization stage under low temperature conditions in winter and the light stage under long daylight conditions in the following spring. After the plant develops through the stages, the flower buds differentiate and bolt. , budding, flowering and fruiting, completing its growth cycle.
