| Abstract | ||
| A field experiment was conducted during the summer growth season of 2012. The experiment aimed to study the effect of roots extract of Glycyrrhiza glabra with 50 and 100% concentration and effect of gibberellin with 100 and 200 ppm on some of morphological and physiological characteristic of Helianthus annuus. The results showed that the two concentration of roots extract of glycyrrhiz increased plant height by 119.86%, 194.24%, leaves number 26.86%, 73.18%, leaf area 53.54%, 215.15%, respectively, dry weight increased 58.80%, weight of 100 grain 85.76%, percentage of protein in grain 26.91% with 50% concentration, the percentage of oil in grain increased 13.62%, 20.80% in 100% , 50% concentration. The GA3 increased plant height 109.94%, 126.46% with 100, 200 ppm respectively, dry weight increased 25.55%, 100 seeds weight 17.50%, percentage of protein in seeds 31.71% and percentage of oil in seeds 10.38% with 200 ppm concentration compared with control plants. | ||
