Effect of Cupric Hydroxide-treated Containers on Bougainvillea Propagation and Growth after Transplanting
Cupric hydroxide (100g Cu(OH)2/liter; 13.3 oz/gal) in a latex paint was sprayed to the interior of propagation cups to evaluate the effects on rooting of Bougainvillea glabra Choisy ‘Sanderiana’ cuttings and their growth after transplanting. Forty-two-day-old rooted cuttings propagated in Cu(OH)2-treated cups had a compact rootball with no root circling and tended to have more primary roots. From 91 to 144 days after transplanting 42-day-old rooted cuttings into non-treated 3.8 liter (1 gal) containers, transplants from the Cu(OH)2-treated cups had a greater growth index, principally due to increased height, than transplants from non-treated cups. However, the CU(OH)2 treatment did not significantly affect shoot or root fresh and dry weights 144 days after transplanting.Abstract
