This study   was carried out  in private  Farm at  Al- kanatier Al-khairyia region during  tow successive  seasons (2008/2009- 2009/2010) to evaluate response of   stem  cuttings of  Bougainvillea glabra plant to rooting  by  auxins and ascorbic acid . The results clearly showed  that, IBA 5000 ppm + ascorbic acid 50 ppm   recorded the highest values in rooting percentage /plant (77 and 80 %) in the first and the second season respectively .Concerning  number of roots / plant, the highest significant values were recorded in both seasons with  IBA 4000 ppm individually , IBA 4000 ppm + ascorbic acid 50ppm and IBA 6000 ppm + ascorbic acid 100 ppm .Measuring of  root length cm/plant ,the highest significant values were recorded with high levels of IBA and NAA individually or combined with different levels of  ascorbic acid .Regarding  shoot length cm /plant   ,the highest significant values were recorded with high levels of IBA and NAA individually  or combined with ascorbic acid in 1^st season , while in 2^nd  season the highest significant values were recorded with high levels of  IBA and NAA individually .
