Bromus Ircutensis Kom Root Growth and Structure
This research investigated the process of Bromus ircutensis Kom’s root growth and development during the seedling age. Three days as time step to sample seedlig roots which grown in greenhouse. Root characteristics of seedlig roots were analysed using EZ-Rhizo software to study the scanned pictures for obtaining roots morphology parameters. Finally, analyzed the data using EXCEL and SAS; The anatomical structures of roots were observed using dyeing and photograph method in the process of microstructure observation. The results showed that development of theBromus ircutensis Kom rootswas mainly represented in the elongation development associated with series of dynamic changing. Bromus ircutensis Kom belonged to monocotyledons, containg roots basic structures: epidermis, cortex and vascular cylinder. The vascular bundles of roots were four and five prototype. The occurrence of lateral root originated in pericycle cells and was endogenous origin.
