COLORADO, Fernando; MONTANEZ, Imelda; BOLANOS, Catalina  e  REY, Jorge. GROWTH AND DEVELOPMENT OF BASIL (Ocimum basilicum L.) UNDER COVER IN THE SABANA OF BOGOTÁ. rev.udcaactual.divulg.cient. [online]. 2013, vol.16, n.1, pp.121-129. ISSN 0123-4226.

The development of basil can be established and quantified by obtaining growth parameters and the characterization of the developmental phases, useful information for its commercial and agricultural management. In this paper it was sought to obtain the TCR, the IAF and the TAN of the species, planted under cover, also to determine their stages of development. The research was conducted in the U.D.C.A between 2010 and 2011 in an area of 70m² with the species Ocimum basilicum L. A population density of 12 plants per m² was used. Height, number of leaves, leaf area and dry weight was measured. The counts were made every four days. The trial was carried up to the start of flowering: 61ddt. Growth parameters were determined using the functional approach of the logistic model with the SAS statistical package. From the analyzed information the physiological efficiency was determined. The development phases were characterized in the same period and were estimated by counting the days elapsed between plant physiological events or observable changes in the variables and determining the physiological efficiency per phase. Three phases of development were identified and growth rates were specified, obtaining maximum TCR values of 0.1082g g^-1 d^-1 at 5ddt; TAN of 0.0083g cm² d^-1 at the end of the 14ddt and IAF of 0.047 at 31ddt.
