| 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... |

| Stevia rebaudiana Bert. es una planta selvática subtropical nativa de Paraguay, que posee un potente edulcorante de hasta 300 veces más dulce que la sacarosa y no tiene calorías. Las moléculas responsables de esta característica son glucósidos de diterpeno, presentes en hojas y sintetizados, al menos en los estados iniciales, usando la misma ruta de síntesis del ácido giberélico, en la que el ácido shiquímico, da origen a muchos compuestos aromáticos. El acetato es el precursor de los terpenos o isoprenoides por la ruta del acetato-mevalonato, donde se encuentran los esteviósidos, aunque en este artículo se discute una ruta alternativa. La presente actualización pretende aportar algunas herramientas para el entendimiento de las principales rutas de... |

| Fruit growth is stimulated by different weather conditions. The aim of this study was to determine the influence of weather conditions on the physicochemical properties of pineapple guava fruit growth. Twenty trees were marked in two production areas located at different altitudes (1,800 and 2,580 m.a.s.l.), and measurements were performed every 7 days from 99 and 141 days post-anthesis to harvest at altitudes of 1,800 and 2,580 m.a.s.l., respectively. The results indicate that altitude and weather conditions greatly influence the growth and development of pineapple guava fruit, and these effects are primarily manifested in the physical characteristics of the fruit. The weight and size of the fruit at harvest are directly related to the altitude of the... |
