| Abstract:
The contractile roots of Crocus sativus are formed from meristematization of parenchyma cells at the base of terminal, lateral buds and corm. When the contractile roots are 1-1.5 cm long, cortex cells are changed and grow horizontally and then collapse. In the end of this process, the contractile parenchymal cells grow more horizontally and cell walls remain, which causes the root to shrink. In the contraction process the central cylinder cells and vessels remain intact. | |
