１、裂根萝卜肉质根开裂，主要是生长过程中土壤水分供应不均匀所导致。苗期遇到高温干旱供水不足时，肉质根周皮层组织硬化，生长中后期温度适宜水分充足时，木质部薄壁细胞再度膨大，且膨大速度远远超过外层细胞，而周皮层及韧皮部的细胞不能相应生长，于是就发生开裂现象。?
1, split root radish fleshy root cracking, mainly due to uneven supply of soil moisture during growth. In the seedling stage, when the water supply of high temperature and drought was insufficient, the cortical tissue of the fleshy root cortex hardened, and when the temperature was suitable for the middle and late growing stage, the parenchyma cells of the xylem re-dilated and inflated more rapidly than the outer layer cells, while the cells of the periplasm and phloem Can not grow accordingly, so cracking occurs. ?
