Abstract : Forced [unspecified method] and unforced, etiolated and non-etiolated mango cuttings were kept under mist in 5 rooting media. Rooting and establishment were better in forced than in unforced cuttings in all media, and were further improved by etiolation. Data are tabulated on the chemical composition of the cuttings; forced shoots contained more moisture than unforced shoots and etiolation increased the moisture content and total carbohydrate in both types. The C/N ratio was much higher in unforced shoots. A medium of peat moss and sand (1:1) was better for rooting than either material alone, vermiculite or soil plus leaf mould. Anatomical differences between the 4 types of cutting were also studied; forcing decreased the number of arched bast fibre bundles and resin canals and etiolation decreased the number of parenchymatons bridges between the cambium and the cortex.
