The indication for use of native species in the landscape has become increasingly more frequent, but find them on the market still is not easy. One reason for this is the difficulty in production, which begins in the processes of propagation. Effective methods of spreading Aspilia montevidensis are not yet known. Thus the objective of this study was to vegetative propagation by cuttings of the rhizome of Aspilia montevidensis in different seasons. Two treatments were tested in each season: T1 – section of the tip of the rhizome and T2– section of the base of the rhizome, with three repetitions each of nine sections in the spring and summer and three replicates of ten sections each fal and winter. The variables were: percentage of rooted cuttings, dead and living, number of roots per cutting, number and length of shoots in each stake. Statistical analysis was performed by the SNK test at 95% probability. There were significant differences between treatments for the percentage of live cuttings in summer and during autumn for the percentage of rooted cuttings (T1= 30.7 % and T2= 0 %), living and the number of roots. In the other treatments and stations there were no statistical differences, although the highest rate of rooting was found in summer (T1 = 73.6 % and T2 = 38.15 %). We conclude that the season is a factor that influences the propagation by cuttings of rhizomes of Aspilia montevidensis.Downloads
