The cause of radish cracking root and its control method

Radish root is a kind of non-invasive disease caused by imbalance of water, and it will reduce the yield and product quality of radish when it is multiple. Radishes are prone to occur in the middle and late stages of growth, and they are mostly cracked longitudinally along the roots of the fleshy roots. The cracks are deep and vary in length. In severe cases, the crack starts from the root head and runs through the roots. There are also transverse cracks near the petiole or radial cracks at the root. Cracked fleshy roots prone to soft rot, intolerant of storage. The main reason for the cracking of radish roots is the uneven water supply. The outermost part of the fleshy root is the cortex, and inward is the phloem, formation and xylem. The xylem is particularly developed and accounts for the vast majority of fleshy roots and consists of a large number of parenchyma cells. In the early growth period of radish, if there is high temperature and drought, the supply of soil moisture will be insufficient, and the cortical tissue of the fleshy root will be aged. In the middle and late period, if the temperature is appropriate, the water supply is sufficient and the parenchyma cells of the roots of the fleshy roots re-expand. However, because the pericyte cells cannot grow accordingly, the fleshy roots are cracked.

Control methods: Improve irrigation techniques, balance water supply, keep the soil at a certain humidity during root enlargement, and do not get too wet.
