Comparative study on the effect of chemical mutagens of sodium azideand di-ethyl sulfate on improving morphological traits and yield components of Borgo officinalis L, plant

Borage seeds were soaked in different doses of sodium azide (SA) and di-ethyl sulphate (DES), at 0.1,0.2,0.3 0.4% for 6 hrs., M2 harvested from M1 plants.In MG1 it was found that most SA increased plant height stem thickness. 0.3% & 0.4%, the ramification main branches enhanced leaves formation, leaf area, FW DW leaves, /FW ratios root length. more effective than 0.2% number. Whereas, MG2, 0.3 % significantly morphological traits, but thickness responded well to 0.1% No. with 0.4 %. A great improvement formation obtained 0.3%.The DW/FW ratios, showed a positive response 0.1 Concerning DES effects 2, results MG1revealed all diameter produced tallest highest gave thickest stems . Applying greatly improved largest area recorded 2000 ppm DES.
