In present study, significant effects of polluted environment were recorded in Hibiscus plants as far as stem metaxylem
area was concerned.

The number of metaxylem
vessel elements showed significant interaction between weeks of collection and dosages of thiamethoxam (Table 3).
epidermis cell area, sclerenchyma area, sclerenchyma bundle area cortical cell area, endodermis area, phloem area, pith area and metaxylem
area were measured with the help of calibrated ocular micromerter under a compound microscope to compare the different root structures of all 9 cultivars, named as Akhrot, Begum Jhangi, Champa Kali, Chohara, Daanda, Daglut Noor, Dakki, Halawi-1 and Halawi-2 (Table I).
Inner wall of epidermic cells are thin; parenchyma composed of polyhedral cells; collateral bundles with a set of sclerenchyma fibers are located at the periphery, each collateral bundle includes two lateral strands of phloem, a central bundle composed of small strands of phloem surrounded with phloematic fibers, a large vessel of metaxylem
, several small vessels of protoxylem and xylematic parenchyma.
The vascular bundles have large metaxylem
vessels with diameters from 189.7 to 238.5 [micro]m.
