The primary metabolites, very abundant in nature, are essential for the physiological development of the plant; they are present in large quantities, they are easy to extract, and their exploitation is relatively cheap. In order to establish mathematical expressions that relate the regrowth age with the nitrogen and sugar content (glucose, fructose and sucrose) of the whole plant and its fractions. The experiment was developed, following a randomized block design, with 5 treatments (60, 90, 120, 150 and 180 d). In the first part of this communication the content of Nitrogen (N) in the integral plant, leaves and stems were evaluated. In the second part we studied sugars like Glu, Frut and Suc. Reporting that N, Glu, Frut and Suc decreased with the highest results at 60 days and quadratic and cubic equations with R2 higher than 0.90 were adjusted. The established regression equations explain the close relationship between regrowth age and the contents of precursor metabolites (N, Glu, Frut and Suc), which explains the fluctuations found in sugars influenced by the MDPI

The objective of this research was to carry out a diagnosis of the working conditions in the panela industry in the Pastaza canton, Ecuador to propose a solution on the priority dangers of occupational accident. The population was made up of 208 workers from 7 panela producers in the Pastaza canton of the Tarqui and Puyo parishes, different field visits were carried out for data collection and instruments were applied such as: checklist, identification guide of Hazards and risk assessment in occupational health and safety Colombian Technical Guide ¨GTC¨ 45. In the analysis of the results, it was evidenced that the workers in this sector have a low level of education, most of them are men, with many years in activity routine and with a lack of knowledge of Occupational Safety and Occupational Health regulations and legislation, with long working hours. 40% of workers carry out heavy lifting, 100% repetitive movements, 80% of workers are exposed to psychosocial risk factors, 60% of establishments have adequate lighting, and 100% present greater risks (fire). The working conditions in the paneleras of the Pastaza canton,
