A research study titled “Effect of different rooting media and coloured polythene wrappers on root characters of guava cv. Gwalior 27”. Fruit Research Station, Entkhedi, Bhopal (M.P.) during 2017-18 and 2018-19. The details of materials used in experimental they have two factors first one rooting media under 3 levels, wrapping materials they have 3 levels and rooting hormone they have 3 levels and 27 treatment combinations with control, the experiment analysed (Pooled Basis) under Factorial Randomized Block Design (FRBD), with three replications. The treatment details are rooting media M1- Soil, M2- Sphagnum moss and M3- Cocopit, wrapping materials W1- White polythene, W2- Red polythene and W3- Black polythene and rooting hormone G1- o ppm IBA, G2- 2000 ppm IBA and G3- 4000 ppm IBA. The observation was recorded under the experiment (shoot charecters) of air layering of guava such as Callus formation, average number of primary and secondary roots per air-layer and average length of primary and secondary roots. The result revealed that the maximum Callus formation, average number of primary and secondary roots per air-layer and average length of primary and secondary roots were found under the treatments of rooting media M₂ (Sphagnum moss)_, followed by M₃ (Coco-pit), Treatment of wrapping materials W₃ (Black polythene), followed by W₂ (Red polythene) and rooting hormone Treatment G₃ (IBA 4000 PPM) followed by G₂ (IBA 2000 PPM), while the minimum was observed under Control.
