IX root development, cell divisions at the root tip are predominantly localized in the first few millimeters of the typical dicot seedling root. These divisions give rise to the cells which form the mature root structure. By differential enlargement and maturation processes these cells form the distinctive mature tissue systems of the primary root: the epidermis, cortex, endodermis, pericycle, ...

Calamus is a climbing palm marked by considerable internodal extension and limited stem-thickening growth, but with a surprisingly discontinuous axial vascular system. Stem bundles end blindly in a basipetal direction and are connected to each other only by narrow and late-developing transverse commissures. Vascular connection via leaf traces between stem and leaf is made over about nine plasto...

The biological effect of white fluorescent light exposure (emitted from an ordinary 30 Watt, 220V fluorescent bare lamp) on the anatomical architecture of Phaseolus vulgaris L.plants obtained from pre-treated seeds was obtained . Both soaked and dry seed lots were separately exposed to light source for 1, 2, 3 & 4 discontinuous periods of one hour with a break time of a complete hr. between eac...

BACKGROUND AND AIMS The capacity of a plant to absorb and transport water and nutrients depends on anatomical structures within the roots and their co-ordination. However, most descriptions of root anatomical structure are limited to 2-D cross-sections, providing little information on 3-D spatial relationships and hardly anything on their temporal evolution. Three-dimensional reconstruction and...

The role of morpho-physiological attributes along with the antioxidant potential Stipagrostis plumosa L. populations collected from arid regions in adaptability to aridity was evaluated. Root shoot length, chlorophyll, carotenoids, and organic osmolytes (total free amino acids, total soluble proteins, glycinebetaine, proline) increased more activities enzymes (APX, CAT, POD, SOD). fresh:dry wei...
