Abstract

This study was carried out in Erbaa/Tokat in a producer greenhouse in 2017. In this study, observations and measurements were made in order to determine the effects of GA3 treatment at different doses ( 0, 150, 300, 450 and 600 ppm) on Gerbera sp. regarding the length and thickness of the pedicle, flower diameter, cut flower weight, yield, vase life, and tillering count. The study was based on a randomized plots test pattern on three consecutive plots. The study was conducted in May, and the growth regulator was applied once each month for three months (June-July-August) by spraying it to the leaves. The results indicate that the GA3 treatment had positive effects in terms of both the yield and the quality, compared to the control group. Evaluation of the effects of various doses applied on the cultivars reveals that the Yeliz cultivar achieved the highest yield with 300 ppm GA3 treatment with 14.66 units per parcel. Similarly, the longest pedicle length was also achieved by the Yeliz cultivar (71.47 cm) with 150 ppm GA3 treatment. The highest flower diameter was achieved by the Ulaş cultivar (133.05 mm) with 150 ppm GA3 treatment, the thickest pedicle was achieved by the Yeliz cultivar (6.40 mm) at 150 ppm GA3 treatment, and the highest cut flower weight was achieved by the Yeliz cultivar (35.935 gr/unit) at 150 ppm GA3 treatment. The longest vase life was achieved by the Ulaş cultivar (16.33 days) flowers treated with 450 ppm GA3.
