| description | The genus Ocimum with over 150 species is characterized by high morphological variability and Chemotypes of great value in the industries of perfumery, cosmetics, food and pharmaceutical features. In order to evaluate the physiological quality of the seeds, in the Experimental Center and the Laboratory of Plant Physiology at the National University of Colombia at Palmira, germination and viability tests were performed with 2,3,5 triphenyl tetrazolium, TTZ. In trials, using a factorial design with five varieties of seeds, three treatments and three replications, the effect of imbibing the seeds for five minutes in Potassium nitrate 0.2% KNO3 and gibberellic acid GA3 250 ppm and 500 ppm respectively as first irrigation and a control (water) was evaluated. The results showed that the seeds from the species O. selloi had the highest percentage (90%) of viability in TTZ and germination (46.2%). The seeds soaked in 0.2% KNO3 showed the highest values of seed germination in three of the five varieties tested. The best responses were obtained with germination seeds O.selloi species (70%) and O. micranthum (58%), followed by Ocimum sp. (26%). The results showed the presence of varying levels of latency, which was partially overcome by the application of potassium nitrate (KNO 3) 0.2%. |
