CHARLO, Hamilton César de O; SOUZA, Samuel de C; CASTOLDI, Renata e BRAZ, Leila T. Performance and quality of tomato fruits of Santa Cruz group in greenhouse with different number of stems. Hortic. Bras. [online]. 2009, vol.27, n.2, pp.144-149. ISSN 1806-9991. http://dx.doi.org/10.1590/S0102-05362009000200004.
An experiment in a greenhouse was conducted to evaluate different orientations of growth of tomato plants, and the effect on productivity. The soil was prepared according to technical recommendations for the culture and soil analysis. Plants were spaced 1.0 m between rows and 0.5 m between plants in the line. The experimental design was comprised of a complete randomized block design, with eight treatments and four repetitions, in factorial arrangement of 2x2x2. Each plot consisted of seven plants, where only the central five plants of each plot were evaluated. Two systems of conduction were used (leaving only one stem per plant and leaving two stems per plant); and two systems of pruning (conventional and differentiated); and two numbers of plants per hollow (one plant per hollow and two plants per hollow). In the conventional pruning all the lateral sprouts were removed and, in the differentiated pruning the lateral sprouts were left, and in these one raceme. We evaluated the number of raceme per plant, height of the first raceme, number of fruits per plant, diameter and length of fruits, thickness of pulp, weight of fruits, number of locules per fruit, diameter of locule, commercial and total yield estimated, pH, titratable acidity, soluble solids and vitamin C. The conduction of two plants per hollow, two stems per plant and conventional pruning type are recommended.
