Abstract

The present study consists in knowing the techniques of asexual multiplication (woody and herbaceous cuttings) of caper (Capparis Spinosa Inermis) family of the capparidaceae, species with high socio-economic value. Cuttings were incised at the base of their ends and then treated with growth hormones at different concentrations(1000, 2000, 5000ppm AIB), grown on 4 types of substrate (Substrate1 (1/3perlite+1/3 sand+1/3 peat), Substrate 2 (1/4 sand+3/4 peat), Substrate 3 (1/2 sand+1/2 peat), Substrate4 (3/4 sand +1/4 peat). Other cuttings were planted in the absence of hormone, according to their order of branching in relation to the mother plants. The main results showed that there are significant differences (p<0.05) between the two types of cuttings, type of substrate and hormone treatment. In fact woody cuttings of smooth caper gave the best recovery percentages (>80%) in substrate 1 with 2000ppm AIB. It should also be noted that herbaceous cuttings are very sensitive to the chemicals presented by the growth hormone. Indeed, the best recovery percentage was obtained for the untreated ones (66%). Since the number of flower buds, which represents the production of capers, is very limited for both cutting techniques.
