| Abstract | ||
| The aim of this study was to evaluate the effect of water stress and herbicide application on seedlings growth of Raphanus rapnanistrum and Hordeum jubatum, Three levels of water stress were applied 2 days , 4 days, and 6 days and control (non stress) treatment with Chevaller herbicide applied to seedling weeds and without herbicide spraying. The result showed the deprive periods increased Proline amino acid content the Raphanus rapnanistrum had high proline amino acid at the 6 days deprive 14.905(µmul/g) compared with non deprive seedling such as for Hordeum jubatum seedling had 6 days deprive high increased proline which 5.953(µmul/g) , the dry whight of seedling Raphanus rapnanistrum decreased at 6 days deprive (0.0027g) and non significantly with 4 days deprive the dry weight radical and rootlets of Hordeum jubatum decreased at 6 days deprive had 0.0037 and 0.0021g respectively. The dry weight of Raphanus rapnanistrum seedling which sprayed with Chevaller herbicide (0.0028g) significantly decreased the radical length compairing without spraying (0.0034g) and non significantly for seedling adjectives Hordeum jubatum. | ||
