| El ensayo se llevó a cabo en la finca El Cortijo (La Vega, Cundinamarca, Colombia [04°55'N y 74°18'W], 2350 m altitud, 17°C temperatura media, 1423 mm precipitación anual, 85% humedad relativa, 1377 horas brillo solar/año). Se utilizaron árboles de feijoa o goiabeira serrana de seis años, Clon 41 ('Quimba'), evaluando fertilizantes foliares KNO3 (Nitrato de Potasio 13-0-46® 1%, 1,5% y 2%) y KH2PO4 (fosfato de potasio; Cosmofoliar 0-32-43®; 0,5%, 0,75% y 1,0%) y la fitohormona ethephon (Ethrel® 48 SL; 100, 150 y 200 mg L-1). Se determinaron el número de botones florales inducidos, flores formadas, además, el porcentaje de flores formadas y nivel de eficacia de los productos inductores. El KH2PO4 al 0,5% obtuvo resultados favorables en cada una de las... |

| The effects of 0, 30 and 60 mM NaCl and substrates (red peat, sand or 3:1:1 [w/w] mixture of peat, sand, or soil) on vegetative growth of lulo, an Andean fruit species, during 12 weeks were studied. The experiment was carried out by using 2000 cm³ of polypropylene plastic pots under greenhouse conditions. Plant height, number of leaves and nodes, leaf area, total plant dry matter (DM), and shoot/root ratio were evaluated. With the increase of salt concentration, the plant height, the number of leaves and nodes, the leaf areas and plant dry mass DM decreased, whereas shoot/root ratio increased. Sand grown lulo plants were most affected by salinity and presented total mortality at 60 mM NaCl. On the other hand, plants held either in peat or in substrate... |
