The paper explains that in all the regions of the world where the growing of mango trees has been developed according to climatology and to grown varieties, some problems linked to flowering and consequently to production have been observed. It recognizes that at this times, there are not yet universal wonder-products in the flowering induction treatment on mango trees. Each country develops its own techniques which are characterized by climatic varietal, technical and commercial constraints and it considers that research and development's organisations must carry out the realisation of this work.
