| Abstract | ||||
| The present investigation was carried out during three successive ears (2000- 2002), in order to study the effect of Murashige and Skoog (1962) medium (MS) supplemented with various concentrations of plant growth regulators on in vitro propagation from shoot tip explants of three grape cultivars namely, Early Superior, Flame seedless and Thompson seedless. The main results of the three lested grape cvs. can be summarized in the following points: 1- The MS medium containing 1.0 mg1·' SA + 0.01 mg1·' NAA produced the hiqhest shoot proliferation percentage, average number of proliferated shoots per shoot tip explant and average length of proliferated shoot from shoot tip cultures. 2· The MS medium containing 1.0 mgr' SA + 0.5 mg1·' zeatin produced the highest shoot multiplication percentage, average number of new proliferated shoots per original shoot and average length of new proliferated shoot from shoot cultures. 3- The 1/2 MS medium containing 0.2 mg1·' ISA produced the highest rooting percentage, average number of roots per shoot and average root length per shoot in shoot cultures. 4· Flame seedless cv. was the super to produce the highest shoot proliferation from shoot tip explant, shoot multiplication from original shoot and rhizogenesis values, followed by Early Superior cv., while Thompson seedless one was the lowest in that respect. | ||||
