Abstract EN

An experimental land conducted inside a lath house belong to kardirash farm / college of Agriculture / sallahal-ddin university (20/10/2010 to 27/2/2011) with Three factora Cutting places( basal and Middle ) plant hormones using three concentrations of seradax (IBA) (0 , 1000 , 2000 ppm) and three treatments of mechanical treatments (without , wonded cutting , wonded cutting and Ringing cutting ).

CRD used in this experiment with duncansmultiple range test at 5% probability as comparing and the result fellows;- 1- The 3 factors or some of them affect apart of result ant not affected other.

2- The second interactions were significant affected on most parameters and not affected others.

3- The third interaction was significant the basal ring cuttings with 1000 ppm of IBA gave a highest length of roots (19.23 cm) compared with alowest length in unwounded unringed basal cutting with no hormones treatment (0.733 cm).

the basal unringed unwounded cuttings treated with 2000 ppm of IBA gave ahighest number of roots (32.0 root/cutting) compared with alowest number of root in ringed basal and unhormone treated cuttings (1.0 root/cutting) also there are no significant deferences in the root dry weight and vegetative shoot number.

While there are a significant deferencesin the vegetative dry weight by the un wounded cutting, middle cutting treated with 2000 ppm of IBA (0.520 gm) compared with (0.116 gm) in un wounded cutting with no hormone.

Also the un wounded ring middle cutting treated with 2000 ppm of IBA gave ahighest percentage of rooting (53.33%) compared with a lowest percentage in the ring basal cutting treated with 1000 ppm of IBA and the middle wounded and ringed cutting treated with 1000 ppm of IBA (6.67%).
