Invitro-Propagation of Threatened African Sandalwood (Osyris lanceolata Hochst. & Steud.) via Using IBA hormone

Abstract

The African Sandalwood plant (Osyris lanceolata) is a threatened shrub or a small hemi-parasitic tree endemic to East Africa and South African regions, which is being severely affected by fungus, uproot-ing for oil extraction, poor natural regeneration, phenological structures (dioecious), medicinal values, lack of sexual recruitment, habitat loss, anthropogenic and climate factors and life span of its seed is short. It has been found a chllange through application of in situ conservation of natural trees like osyris lanceoleta since rapid human population growth and dramatically change the demands of fuel wood and agriculture investement, the available natural strands of valuable plants of African sandalwood have not been able to meet the demands of the people in world specifically developing countries. How ever, this study via using the advances of plant propagation method it provide new options for conserving and multiplication of Osyris lanceolata species using in vitro culture techniques of using IBA hormone by taking plant material of the targated plant. Propagation of African sandalwood (Osyris lanceolata) by rooting hormone of IBA in non-mist poly-propagator was investigated by taking young stem of osyris lanceoleta from Bazawit Hill and we provide an alternative propagation technique to the use of seeds. This Hill is near to Bahrdar town, Ethiopia.New leaf were initiated on the young stems of the osyris after six weeks of the experment.The influence of IBA as rooting promoter at three concentrations (50, 100 and 150 ppm) were recorded.Un expectedly, from the data collected it was observed that the success 83.3% can be achieved from young stem of un treatead cuting gave a new leaf and 50% were achived in the treatead plant, this propagation technique is a viable alternative to seed. The success may influenced by application orgin of a stem cutting with a type of soil.
