چکیده
|
Damask rose is one of the aromatic and medicinal plants belonging to the rosacea family whose essential oil has nutritional and economic value. the purpose of this research was to determine the location of the hormones effects in organ tissues for the formation of calluses, buds and roots. for this, we have studied hormone effects on the callus, shoot, root formation, and anatomical alternate. we found iaa and 2, 4-d with bap were affected by callus, shoot, and root production from damask shoot explants. regeneration organs were undifferentiated to callus after two weeks. to avoid this problem, we suggest that it is better to subculture explants in a new medium with fewer hormones. the site of callus, shoot, and root formation was the node on the explant. this explant node had a lateral meristem. the anatomical study of explants showed that the origin of callus, shoot, and root formation is cambium parenchymal cells.
