Effect of Warm Medium, Light Intensity, BA, and Parent Leaf on Propagation of Golden Pothos

Year: 1987

Type: article

Abstract: Photosynthetic photon flux (PPF) at 290 μmol·s -1 ·m -2 and warm propagation medium (28°C) enhanced both shoot and root growth of golden pothos ( Epipremnum aureum ) from single-node leaf-bud cuttings compared to PPF at 60 μmol·s -1 ·m -2 and unheated medium (10° to 16°). Heated cuttings accumulated much more dry matter in new growth, but parent leaves had smaller area leaf weight than unheated cuttings. Soaking cuttings in 500 or 750 ppm BA before planting caused slower initial growth of the axillary shoot, and stem length was reduced to 75% of the control. Leaf number and total leaf area was unaffected by BA. Leaf-bud cuttings needed 10 more days to unfold the first leaf compared to stem cuttings without parent leaves. Shoots developed from leaf-bud cuttings had longer stems, more leaves and total leaf area, and heavier dry weight than shoots from stem cuttings. Chemical name used: N -(phenylmethyl)-1 H -purin-6-amine (BA).
