Abstract
The root system of M. deliciosa is composed of 3 types: aerial, aerial-subterranean and lateral subterranean. The 3 roots types differ in the longitudinal and transverse distribution of trichosclereids and raphide crystal idioblasts. The longitudinal distribution of both idioblasts was related to the length of the elongation zone in each root type. The greatest number of intact raphide cells was distal to the elongation zone; the greatest number of mature trichosclereids was proximal to the elongation zone. In cross sections, trichosclereids were found primarily in the middle regions of the cortex. However, the majority of raphide crystal cells were in the outer cortex. Subterranean roots had a higher percentage of raphide crystal cells in the outer cortex than did aerial roots. Functional, intact raphide cells and mature trichosclereids were intermixed only slightly in either their longitudinal or transverse distribution.
