Introduction Meristem-tip culture has been widely used in clonal micro-propagation of higher plants during the last three decades. The most important application ofmeristem culture is in the production of virus-free plants, rapid multiplication and also in the long-term storage of such virus-free clonal germplasm through cryopreservation techniques (QuAK 1977; KARTHA 1981). Although the theoretical aspects of virus eradication from plants by meristem-tip culture is not clear yet, ever since the pioneering work ofLIMASSET and CoRNUET (1949) this technique has been the most efficient method of eliminating viral pathogens from crop plants. Several workers reported that grapevines have been fully freed of certain \'lide-spread viral pathogens such as fan leaf, leaf roll and yellow speckle, either by meristem culture alone or meristem culture in combination v:ith thermotherapy (BARLASS et al. 1982; GRENAN 1984; BLAICH 1985). In the past decade, numerous studies were carried out to explore the reactions of Vitis species to meristem culture for the above-mentioned purposes (FAYRE 1978; BARLASs and SKENE 1980, 1981, 1982; CHEE and PooL 1983, 1985; GRAY and F1sHER 1987; FANIZZA 1987; ALLEWELDTand HARST-LANGENBUCHER 198 7). Materials and methods As the basic plant material, apical meristems that are 0.5 mm in length with two or three leaf primordia, isolated from growing tips of current shoots ofKalecik Karasi ( V. vinifera L.) which is a superior red wine variety, and 41 B M.G. (Chasselas x V. berlandien) which is a difficult-to-root and lime resistant rootstock variety, were used in the experiments which were carried out in three consecutive steps: Experiment I: Effects of various concentrations (4/4 MS, 314 MS, 2/4 MS) ofagar-solidified (0.8 %) standard MuRASHIGE and SKooG (1962) medium supplemented with sucrose (3.0 %) and BAP (2.5 mg/I) (CHEE and PooL 1985) with three combinations ofGa3 at 0.0, 0.1 and 0.5 mg/I on success of the meristem cultures in establishment medium. 456 Section 5 Table 1: Effects of MS concentrations, GA3 and vitamin formulations on success of the cultures in establishment medium Survival rate {f.)

E x p e r i m e n t I I I : Effects of 15 auxin (IBA) x cytokinin (BAP) combinations in the above-mentioned MS medium supplemented with 0.5 mg/I GA3, designed with a predominance ofBAP in shoot proliferation medium and IBA in rooting medium, on shoot and root formation and development of the cultures. Cultures were incubated at constant temperature of 25 °C, 16 h photoperiod (4000 lux) and 70 % relatiYe humidity during establishment (3 weeks), shoot proliferation and rooting subcultures (5 weeks in each stage) (WETHERELL 1982; HARRIS and SrEYE'..'SOK 1982). Results and discussion Experiment I Highest su1Vival rates of the meristem cultures for both Kalecik Karasi (75.0 %) and 41 B M.G. (67.9 %) were obtained from 4/4 MSx 0.5 mg/I GA3• Similarly, the same combination also gave better results in the development of survival meristems for both genotypes (Table 1, Fig. l). Experiment II As shown in Table 1, all meristems ofKalecik Karasi which were cultured in standard MS medium with the combination of the three vitamin fonnulations were still alive. However, survival rates of 41 B meristems were above 90.0 % in MS vitamin and thiamine+ meso-inositol, but 72.5 % in Morel vitamin. The rates of growing meristems are also similar to that su1Vival data. Tissue and cell culture 457 Experiment III For both genotypes, 0.0 mg/I IBA x 1.0 mg/I BAP and 0.5 mg/I IBA x 1.0 mg/I BAP combinations gave better shoot proliferation and development in shoot medium (Table 2, Fig. 2). On the other hand, satisfactory rooting rates (above 50.0 %) were obtained with those combinations in Kalecik Karasi. The combination containing only BAP at 1.0 mg/I also produces entire plants at the rate of 42.9 % in the same genotype. These data are in agreement with the reports of SKENE and BARLASS (1980), HARRIS and STEVENSON (1982), MAsAHIKO et al. (1982). Although the data concerning shoot development in 41 B were generally similar to those ofKalecik Karasi, as a result ofinefficient rooting, an entire plant production rate of18.8 % was only achieved in the combination containing 0.5 mg/I IBA and 0.5 mg/I BAP. Results on rooting and entire plant fonnation in rooting medium were found to be rather different according to the genotypes. Highest root formation was obtained in the combinations of 1.0mg/l IBAx 0.0mg/l BAP (86.7%) and 1.0mg/l IBAx 0.5mg/l BAP (85.7%) for Kalecik Karasi; 5.0mg/l IBAx O.Omg/l BAP (100.0%), followed by 2.5mg/l IBAx 0.0mg/l BAP (90.0%) and 5.0mg/J IBAx 0.5 mg/I BAP (90.0%) for 41 B. In entire plant formation, similar combinations as above gave the best results: 1.0 mg/I IBAx 0.5 mg/I BAP (71.4 %) and 1.0 mg/l IBAx 0.0mg/l BAP (66.7%) for Kalecik Karasi; 5.0mg/l IBAx 0.0mg/l BAP (80.0%) and 5.0mg/l IBAx0.5 mg/I BAP (70.0%) for41 B (Table3, Fig. 3).
