Abstract
The objective of this study was to analyze the use of different doses of indolebutyric acid (IBA) and its influence on reducing sugar contents and the relationship of root and leaf development of mulberry cuttings, using commercial substrates and sand. The experimental design was a completely randomized design, with 3 replicates per plot and 5 cuttings per replicate, in a 3 × 3 factorial scheme, consisting of three IBA doses and three substrates: commercial substrate, sand and 50% substrate with 50% of sand. The cuttings planted on substrate presented a higher percentage of rooting in the treatments with 0 and 1000 mg L-1, differing from the other substrates, which represented increases of 16.68 and 44.45% in relation to the substrate of sand and sand + substrate, respectively. In the control treatment, estimates of the reducing sugar content of the leaves showed interaction between the substrates and doses of IBA, presenting an increasing quadratic effect for the treatment. It is concluded that the use of commercial substrate provides greater development of primary leaves and root length; the concentration of 1000 mg L-1 of IBA was higher among the analyzed doses. The reducing sugar content of the cuttings influenced the growth of the shoots. Key words: Reducing sugars, fit regulator, multiplication, Rubus, substrates.
