Enraizamento de estacas, cobertura plástica e densidade de plantio na produção e qualidade das frutas da framboeseira ‘Batum’

Abstract

The objective of this study was to increase the production of raspberry, improve quality and increase the production of seedlings. To achieve the proposed goals were conducted experiments from March 2012 to June 2013. Cuttings of raspberry ' Batum ' were cold-storage (4 ° C) for 10, 20 and 30 days, and the control without storage. Subsequently, the cuttings were treated with IBA ( 0, 1000, 2000 , 3000 and 4000 mg L- 1) and root cuttings with BAP ( 0, 300, 600, 900, 1200 and 1500 mg L- 1) in a completely randomized design. It was concluded that the use of stem cuttings is not viable and root cuttings need not be cold storage and treated with BAP. In the second experiment, the experimental design was randomized blocks, factorial 2 x 2 with 6 blocks and 10 plants per plot. Were assessed the fruit color , total anthocyanins, vitamin C , ash, humidity, soluble solids, sugars, acidity, firmness, rust incidence on fruits and mineral composition (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, manganese, zinc and iron). At the end it was observed that cultivation with 3 x 0.25 m spacing and plastic cover on plants increased the quality of raspberries. Plants arranged in dense spacing (3.0 x 0.25 m ) produced 11.55 t ha - 1, almost 20 % higher productivity than the one presented by the plants in less dense spacing (3.0 x 0.5 m ), which was 9.25 t ha -1. With these results it was concluded that the highest density of planting and planting with plastic cover over the plant canopy result in higher fruit quality and higher productivity.
