Solenostemon rotundifolius is a tuberous plant with great food and economic potential in Burkina Faso. One of the major problems in its production is the loss of seedlings during storage, resulting in a shortage of raw materials at planting time. The aim of this study was to assess the effectiveness of methods for preserving S. rotundifolius seedlings. A randomized block design with three (03) replicates was used. Twelve (12) preservation methods were tested. Measurements were made on the rate of budded seedlings, budding time, bud length and seedling loss rate. The results showed that six (6) conservation methods produced seedlings with a budding rate of over 80% and low seedling loss rates, ranging from 2.38% to 6.19%. These are: conservation in “Bitatoré” with millet husks as additive (BITA+G) with a seedling budding rate of 89.05 ± 2.27%, canaries with sand as additive (CAN+S) with a budding rate of 87.62 ± 2.17%, “Bitatoré” without additive (BITA) with a budding rate of 86,19 ± 2.33%, Storage in Sand and Sprouting (Tri S) with a budding rate of 85.71 ± 2.72%, canaries with wood shavings as additive (CAN+CB) with a budding rate of 85.24 ± 2.35% and canaries without additive (CAN) with a budding rate of 85.24 ± 2.54%. In addition, the seedlings produced by these methods had respective seed loss rates of 2.86%, 2.86%, 6.19%, 2.38%, 3.81% and 5.71%. The results also showed that seedling budding time varied from 51 ± 4 to 70 ± 3 days, depending on the storage method.
