The dynamics of the carbohydrates accumulation in Solanacee leaves cultivated in different technological systems

Abstract

Our research about cultivated plants from protected spaces(greenhouse and solariums) observed the variation
of the carbohydrates parameters in different technological systems(ecologic and conventional). It were studied species
from the Solanaceae Family such as: Lycopersicon esculentum Mill (tomato), Capsicum annum L.(sweet pepper) and
Solanum melongena L. (eggplant). Sugars metabolism was evaluated through analysis of the mono-, di and
polysaccharides at the different phenophases: flowering, ripening and maturity. It was made a comparison between the
sugars accumulation in leaves depending of the fertilizing technology (chemical or organic). The sugar parameters have a
more accelerated dynamics in conventional culture systems than in ecologic one. In this technological system (classic),
carbohydrates have a decreasing dynamics from flowering until ripening, meanwhile the accumulation of the
carbohydrates in leaves of plant from ecologic systems have an increasing curve. Disaccharides were well represented in
studied plant, in all phenophases, indifferent of type of the protected spaces (solarium or greenhouse).
