Efecto de la aplicación de yodo en la germinación de semilla de tomate de árbol (Solanum betaceum)

Abstract

The tree tomato has its origins in the Andean forests of South America, in Ecuador this crop is of great importance for farmers because it favors their economy. However, obtaining new plants presents limitations such as a low germination percentage, more susceptible to pests and diseases. This makes clear the lack of knowledge of techniques necessary to germinate new plants, therefore the use of iodine for tomato seed germination was proposed in a completely randomized experiment where 9 treatments and a control with 3 replicates were evaluated, each treatment had different concentrations of iodine 1%, 5% and 10% submerged in 6, 12 and 24 hours, 10 samples were taken from each experimental unit, the data evaluated were: germination percentage with a 90. The greatest plant height was obtained in treatments A3B1 (10% iodine, 6 hours of immersion) with an average plant height of 13.18 cm and A2 B1 (5% iodine, 6 hours of immersion) with a height of 12.94 cm. The largest root volume was obtained with the A2B1 (5%, 6 hours of immersion) and A3B1 (10%, 6 hours of immersion) treatment with 0.27 cm3 for the two treatments. The greatest root length presented the A3B1 treatments (10% iodine, 6 hours of immersion) with an average root length of 24.25 cm. Treatment A1B1 (1% iodine and 6 hours of immersion) presented 0.6 ug/g of chlorophyll concentration, these data were obtained from planting.
