DEVELOPMENT VEGETATIVE, PRODUCTIVITY AND GAS EXCHANGE OF SOLANUM SESSILIFLORUM DUNAL GROWN IN PROTECTED ENVIRONMENT AND THE FIELD

Abstract

Growing cubiu (Solanum sessiliflorum Dunal) is still very limited, mainly due to lack of technical information about the culture, creating a necessity to obtain knowledge about the adaptation and phenology, thus, improve the technological management. In the context of this information, the present study aimed to assess gas exchange and vegetative growth parameters and productivity cubiu in greenhouse and field. To run the experiment cultured cubiu in the external environment (field) and in a protected environment (en-vegetation), evaluating parameters of vegetative (stem diameter, plant height, and canopy volume), productivity (number of commercial and non-commercial fruits, and total production of commercial and non-commercial) fruit, gas exchange and SPAD index. Through the results it was found that performing the cultivation of cubiu the field are obtained better photosynthetic performance and water use efficiency (USA) and greater vegetative development and production of marketable fruits
