17. The method according to claim 1, wherein the treatment comprises contacting the Cannabis plant or the part thereof with the dinitoaniline compound. (1) (0)

19. The method according to claim 1, further comprising obtaining a plantlet by culturing the treated Cannabis plant or the treated part thereof in a shoot elongation media for a time sufficient to induce rooting. (0)

20. The method according to claim 1, wherein the treated Cannabis plant or the treated part thereof is placed to a rooting hormone comprising medium for a time sufficient to induce rooting. (0)

21. The method according to claim 1, wherein the polyploidy is tetraploid. (0)

22. A polyploid Cannabis plant or part thereof obtained by the method as defined in claim 1. (0)

23. A Cannabis plant cell obtained by the method as defined in claim 1, wherein the Cannabis cell is polyploid. (0)
