Bauhinia x blakeana (B. purpurea x B. variegata) is a natural hybrid that has been cultivated in gardens, streets and parks. Due to its sterility, it must be vegetatively propagated. The objective of this work was to evaluate the viability of cuttings and grafting on its propagation. Semi-woody cuttings were collected during four seasons and treated with 0; 1,000; 2,000; and 3,000 mg L-1 of IBA. The experimental design was entirely randomized and the treatments were arranged in a 4x4 factorial scheme (four collecting times x four IBA concentrations) and five replications with 10 cuttings each, per collecting time and per IBA concentration. Characteristics of roots and shoots were evaluated after 90 days. The data means were compared by the Tukey test and submitted to the polynomial regression analysis. For the grafting experiment, B. variegata and B. variegata var. candida plants of six and 12 months were used as rootstocks and the splice graft and T-budding methods were tested. The experimental design was entirely randomized and the treatments were arranged in a 2x2x2 factorial scheme (two rootstock species x two grafting methods x two rootstock ages) and four replications with five plants each, per rootstock species, per grafting method and per rootstock age. Characteristics of shoots were evaluated after 90 days and the data means were compared by the Tukey test. B. x blakeana can be propagated by semi-woody cuttings collected in spring, without IBA application, or in summer, with the application of 3,000 mg L-1 of IBA. The tested grafting methods were not effective.

ABSTRACT: Lychee is one of the most popular exotic fruits in Brazil, and has both in natura and industrial potential. The objective of the present study was to evaluate the influence of the number of leaflets on lychee herbaceous cuttings treated with the indolebutyric acid (1000mg L-1). The experimental design was completely randomized, with 4 replications and 10 cuttings per experimental plot. Treatments consisted of cuttings with zero (0), one (1), two (2), three (3), and four (4) leaflets. After 180 days, the rooting and survival percentages and the number and length of roots were evaluated. The data were subjected to polynomial regression analysis. The increase in the number of leaflets was advantageus for all studied variables, with an increase in the survival, rooting of cuttings, and number and length of roots. The herbaceous cuttings of lychee tree are viable, provided that at least four leaflets remain in the herbaceous cutting.
