The objective of our work is to study the answer of was to study the response offive vine variéties ( Vitis vinefera L.) to the in vitro culture. The design employed counts two basic mediums, MS and NN, complemented with various hormones. Explant response was measured through leaf emission and leaf extension, roots emission and the ability to acclimation. Results showed that MS was globally more efficient as growth medium as far asgenotype response was concerned. Certain varieties exhibited a specific behavior toward a medium or the other for the measured variables. Only one variety, the 140 Rshowed a large adaptation to mediums and hormones used for the initiation of callus, morphogenesis, rhizogenesis and acclamation.Références
