The effect of different ratios of coco peat and expanded clay on rooting and growth of pothos (Epipremnum aureum) stem cuttings

The esthetic and psychological enhancement of interior environments and purification of the indoor air have become catalysts in promoting foliage plant production and increasing their wholesale value. Pothos is one of these popular indoor plants which it has beautiful leaves and stems. The propagation method is by stem cuttings and the composition of the culture medium will affect the rooting and growth of the cuttings. Therefore, this study was performed in a completely randomized design with 5 treatments (different ratios of coco peat and expanded clay) to compare rooting and growth of the pothos stem cuttings. The compositions of these five potted mixtures were by volume: 1. 100% peat, 2. 100% expanded clay, 3. 50% coco peat +50% expanded clay, 4.75% expanded clay +25% coco peat and 5. 75% coco peat +25% expanded clay. The results showed that the highest root and leaf fresh and dry weight, leaf number, root volume and the longest root length related to 50% coco peat +50%expanded clay. Therefore, this pot mixture can be recommended for the propagation of this plant by stem cuttings.
