Auxins are the only compounds used in commercial plant propagation to stimulate rooting, although efforts have been made to find other efficient compounds. Another group of rooting promoters could be plant growth retardants (PGRs) which act as inhibitors of gibberellin synthesis. The aim of the experiment was to determine the effect of flurprimidol and naphthalene- 1-acetic acid (NAA) applied by quick-dip method on rooting and development of Fuchsia hybrida ‘Swingtime’ cuttings and their subsequent growth. Anatomical analysis of the rooting process was also done. Flurprimidol and NAA did not influence the percentage of rooted fuchsia cuttings but increased the number of adventitious roots. Both compounds were involved in earlier formation of root primordia. Flurprimidol and NAA, used simultaneously or separately, increased the number and length of axillary shoots of fuchsia cuttings. The effect of flurprimidol on the number of roots and shoots was stronger than that of NAA, but diminished after transplanting the rooted cuttings. The influence of flurprimidol on axillary shoot length was weaker as its concentration increased.

Auksyny to jedyna grupa związków stosowanych w produkcji roślin w celu stymulowania ukorzeniania, chociaż podejmowane są wysiłki w celu znalezienia innych skutecznych preparatów. Inną grupą stymulatorów ukorzeniania mogą być retardanty wzrostu roślin, których działanie polega na hamowaniu syntezy giberelin. Celem doświadczenia była ocena wpływu fluropirimidolu i kwasu naftylooctowego podawanych metodą quick-dip na ukorzenianie i rozwój sadzonek fuksji ogrodowej ‘Swingtime’ oraz ich wzrost następczy. Przeprowadzono także analizę anatomiczną procesu ukorzeniania. Fluropirimidol i NAA nie wpłynęły na procent ukorzenienia sadzonek fuksji, zwiększyły natomiast liczbę korzeni przybyszowych na sadzonkach. Obydwa związki przyspieszały tworzenie zawiązków korzeni przybyszowych. Fluropirimidol i NAA, zastosowane razem lub osobno, zwiększały liczbę i długość pędów bocznych na sadzonkach. Wpływ fluropirimidolu na liczbę korzeni i pędów bocznych był silniejszy niż NAA, ale zanikał po przesadzeniu ukorzenionych sadzonek. Wpływ fluropirimidolu na długość pędów bocznych słabł wraz z jego wzrastającym stężeniem.
