Fungicide Treatment Increases Sprouting Percentage and Sprout Growth for Paulownia tomentosa Root Cuttings
Root cuttings are widely used to propagate paulownia--- Paulownia tomentosa (Thunb.) Steud.— for nursery bed establishment, and they can be used to establish plantations. However, the success of outplanted cuttings may be limited by rot. This study showed that paulownia root cuttings soaked in a general-purpose fungicide solution had higher sprouting success (68.3%) than untreated cuttings (21.2%) when planted in silty clay soils. When planted in silty loam soils, sprouting success was similar for treated and untreated cuttings. But treated cuttings in silty loam soils produced sprouts of greater average height (74.1 cm, or 28.9 in) at midseason than did untreated cuttings (48.6 cm, or 19.0 in).
