Özet

This experiment was conducted to reveal the effects of PGPR and IBA on rooting characteristics of Ramsey "Salt Creek" (Vitis champini) under the nursery. Hard wood cuttings of Ramsey were subjected to PGPR (EMA1, EMA6, EMA24, EMA MEDIA, EMA CALLUS, EMA QUICK DIP) with dipping times of 1h, 6h, 24 h. IBA concentration was 25, 2000, 4000 ppm with dipping time of 24 h in the case of long-soak method, and of 4 seconds in quick dip method. Data were recorded on specific rooting and shooting characteristic. Results obtained from treatments showed significant differences at p <= 0.01 for specific rooting characteristic, like rooting rate (%), rooting degree (0-4), root length (cm), root fresh and dry weight (g) under the interaction between PGPR and IBA concentration and dipping time. The rooting rate of EMA1 was 56.7%, and was better than in IBA treatments. Rooting degree (0-4) was 3.5 with EMA1 and 3.3 with EMA MEDIA. The highest root lenght (cm) were obtained in IBA25 (37.6) EMA MEDIA (37.2) and EMA1 (34.1). The best result on fresh root weight (g) was determined with EMA1 (9.8) and EMA6 (9.5). As a conclusion, inspected rooting characteristics generally increased with the EMA1 and EMA6 treatments.
