Evaluation of uva camarona (Macleania rupestris Kunth A.C. Smith) propagation with air layering
Uva camarona (Macleania rupestris Kunth A.C. Smith) belongs to the Ericaceae family and grows in páramo and subpáramo areas in Colombia, between 2,200 and 3,500 m a.s.l. This plant presents edible berries that serve as a source of food and small income for local communities. The absence of a propaga...

This study aimed to evaluate the effectiveness of asexual propagation of M. rupestris with air layering, using indole-butyric acid (IBA) as a rooting hormone at different concentrations: 0, 500, 1,000, and 2,000 mg L-1. The results showed that an exogenous application of IBA accelerated the rooting process in the layered zone, with a notable emission of first adventitious roots at 60 days from the start of the experiment. The treatments of 500 and 1,000 mg L-1 IBA had the highest number of roots per layer, being two to three times higher than those presented in the control. No significant differences were seen in root length between treatments. The treatments of 500 and 1,000 mg L-1 IBA showed a high production for the dry weights of the roots and callus, with a higher weight of callus compared to root weight. Air layering negatively affected the longitudinal growth of the branches, since their average growth rate was 1.49 cm per month, while the growth of intact branches was 2.78 cm per month. The results suggest that the best concentration for rooting was 1.200 mg L-1 IBA because it had the largest number and dry weight of roots in air-layered M. rupestrishttp://www.scielo.org.co/scielo.php?script=sci_arttext&pid=S0120-99652013000100003&lng=en&tlng=enEricaceaeácido indolbutíricopropagación vegetativaraícescallo |
