EFFECT OF TEMPERATURE, SCALE POSITION, AND GROWTH REGULATORS ON THE BULBLET FORMATION AND GROWTH DURING SCALE PROPAGATION OF LILIUM
This experiment was carried out to investigate the effect of temperature during scaling, scale position and growth regulators on the bulblet formation and growth when Lilium species and hybrids are scale propagated. The number of bulblets from L. speciosum, 'Stargazer' was the highest when propagated at 25°C, while other hybrids or species was at 20°C. After three of scaling propagation of 'Stargazer', 1.1–2.9 bulblets were formed, and the number was increased to 6.5 after 5 months. Scales obtained from the outer and middle scales of the bulb tended to produce the most number of bulblets, which can be correlated with the total carbohydrate content in those scales. Bulblet formation and growth was the best when 'Stargazer', L. longiflorum, 'Gelria' and L. lancifolium scales were treated at 300 ppm, 100 ppm naphthyl acetic acid (NAA) and 100 ppm indole butyric acid (IBA), respectively. After 6 weeks of 5°C, dormancy was broken in all lilies as judged by the scale leaf emergence.
