Abstract:

In order to study the asexual reproduction method of lavender in subtropical regions intensively and to verify the feasibility of establishing lavender breeding bases in southern regions, the effects of different substrates, different parts of the branch, different concentration of IBA hormone and different treating time on the cutting of L. dentata, L. heterophylla and L. pinnata were studied in Nanning. It showed that the cutting effects of L. heterophylla was obviously better than that of L. dentata and L. pinnata. Sand and perlite could be used as the cutting substrate. The middle branch was more suitable for cuttings. The effects of IBA concentration and treatment time on different lavender varieties were different. Integrated analysis implied that the optimum cutting conditions for L. heterophylla, L. dentata and L. pinnata were as follows respectively: middle cuttings + sand + 1000 mg/L IBA 60 s, middle cuttings + perlite +1000 mg/L IBA 30 s, base cuttings + sand + 500 mg/L IBA 15 s. The experiment indicated that raising lavender seedlings of the three varieties was feasible in Nanning.
