Abstract
The experiment was carried out in research station of crop department in College of Agriculture and forestry/Mosul University in the year of 2008 and 2009. The Plant Growth Regulators (PGR) was applied and which consist Gibberellic acid (GA3) and Kinetin (Kin) at (100 ppm ) concentration in each of them. The Plants was spread after one and two week from cutting at each of Tillering and Jointing stage. The results of study show the cutting treatments cause a decrease in characters study while the treatment with Gibberellin (GA3) and Kinetin reduce of this effect .The two Plant Growth Regulators cause significantly increase in most of characters studies specially in tiller number. The plant treated with Kinetin given ten foliage shoots, eight shoots of them fruited compared with eight foliage shoots in untreatments plants which 3.6 was fruited only (controle treatments). Also the biological yield increase by adding GA3 or Kin of the cutting plants compared with untreatmented cutting plants. The interaction between (Kin) and (GA3) show a similar effect in increase vegetative growth characters and in yield and weight of seed specially in early stage at tillering stage. The GA3 alone super passed in number of seeds and their weight, while the Kin was super passed in seeds plant yield significantly,which reached to 142.1 gm in tillering stage compared with 70.68 gm in untreatmented cutting plants at same stage.
