Effects of Different Growing Medium on Obtaining Bulblets from Bulb Scales in Oriental Lilium 'Siberia' Cultivar

Abstract

This study was carried out to determine the best medium for obtaining bulblets in the Oriental Lilium 'Siberia' plant using bulb scales and different media. In the research, six different growing mediums were used as growing media: soil (control), peat, soil + peat, perlite, perlite + peat, and peat + sand. In the experiment, the number of bulblets, bulblet width, bulblet length, number of healthy and infected bulb scales, and the time it took for the first bulbs to formation were measured. As a result of the study, the highest number of bulblets (110) were obtained from peat + sand. The growing medium with the highest values of bulblet width (11.38 cm) and bulblet length (16.27 cm) was determined to be peat. The highest number of healthy bulb scales (54) was obtained from perlite medium, and the highest number of infected bulb scales (20) was obtained from soil medium. In terms of the formation time of the first bulblets, perlite medium (15 days) was the growing medium where the earliest bulbs were obtained, and the latest bulblets were obtained from control (soil) and soil + peat (40 days). In general, the quality of bulblets obtained from peat medium was better than that from other mediums. In this regard, peat growing medium is recommended to obtain quality bulblets, and peat + sand is recommended if the number of bulblets is desired to be high.
