    DIFFERENT APPROACHES ON BULBLET FORMATION WITH SCALING IN MADONNA LILY (LILIUM CANDIDUM)
    (Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Akcal, Arda; Kahraman, Ozgur
    The purpose of this study was, to determine the effects of different treatments on bulblet formation with scale propagation in 'Madonna lily' (Lilium candidum). The research was conducted in growth chamber at Eanakkale Onsekiz Mart University, Faculty of Agriculture, Department of Horticulture in 2015-2016. Scales of Lilium candidum bulbs with 22-24 cm circumference, were used as a plant material. Effects of different incubation periods (10,12,14 weeks), incubation temperatures (10-15 degrees C, 20-25 degrees C), auxin (IBA 100 ppm, IBA 200 ppm) doses and scale positions (outer, middle, inner, center) on bulblet formation were investigated. The experiment was established according to randomised plot design with 3 replications. Some parameters like, bulblet formation ratio, bulblet number per scale, weight, diameter and height of bulblet, scale number, root number and root length of bulblet were also determined. As a conclusion, treatments have not any significant effect on bulblet formation ratio, but there were significant differences between the other parameters for some of treatments. In spite of this, incubation period of 14 weeks gives the highest average value for bulblet number per scale (1.467 piece) and bulblet height (19.105 mm). Also, the highest average value of bulblet weight (0.792 g) and bulblet diameter (13.282 mm) were measured in outer scales. While incubation temperature of 10-15 degrees C gives the best result for bulblet scale number (3.511 piece), the highest average value for root number of bulblet (3.900 piece) and root length of bulblet (11.224 cm) were measured in auxin dose of 200 ppm IBA.

    Effect of Sucrose Rates in Propagation of Summer Snowflakes
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2019) Kahraman, Ozgur
    Leucojum aestivum L. is one of the species that is allowed to be exported in natural flower bulbs with quota limitation from production. By the regulation, summer snowflakes with above 7.5 cm bulb circumference are allowed to be exported. Increasing the bulblet circumference of the bulblet obtained from propagation in a short period of time is important for the protection of natural spreading summer snowflakes. This experiment was conducted to determine the effects of different sucrose ratios on bulblet formation and development. Summer snowflakes bulbs with 8.5 cm length were cleaned and divided longitudinally into four parts. The segments were placed in black polyethylene bags filled with 3 liters of perlite and then 2 more liters of perlite was added to the bag. Each bag maintained with 10 segments. The bags were irrigated with tap water (control), 1% sucrose containing and 2% sucrose containing water, respectively, and they were incubated for 12 weeks. After incubation; the effect of different sucrose ratios on the rate of bulblet formation, bulblet length, bulblet diameter, bulblet weight, bulblet number, root number and root diameter were found insignificant. However, the effect on root length was found to be significant with 95% confidence. The bulblet weight varied from 1.07 g to 1.23 g and the bulblet diameter ranged from 8.67 mm to 9.37 mm. The highest root length (30.39 mm) was found in 1% sucrose treatment.

    Enlarging of Grape Hyacinth Bulb at Different Nutrient Solution Ratios in Soilless Culture
    (Taylor & Francis Inc, 2022) Kahraman, Ozgur
    Grape hyacinth bulbs must be of a certain size in order to bloom. It is commercially important to extend the circumference of grape hyacinth bulbs in a short time. This study was conducted to determine the effects of different nutrient solution rates on the bulb enlargement, the bulblet formation and plant growth characteristics in soilless culture. Grape hyacinth bulbs (Muscari armeniacum Leichtlin ex Baker) with a circumference of 3 cm were grown in perlite bag culture at six different nutrient solution rates (25%, 50%, 75%, 100%, 125% and 150% of the final nutrient solution). According to the variance analysis; the effect of nutrient solution ratios on bulb diameter, bulb weight, bulblet number, adventitious root number, adventitious root length, adventitious root weight, leaf length and leaf weight was found to be insignificant. Bulb diameter enlarged between 14.44% and 29.13%. Bulb diameter varied between 10.95 mm and 12.20 mm, bulb weight 0.74-0.90 g, bulblet number 1.00-1.56 piece, leaf length 23.05-27.33 cm. Electrical conductivity (EC) of drainage waters increased with increasing nutrient solution ratio. A positive correlation was determined between leaf number and bulb diameter, nutrient solution ratio and EC. In addition, a positive correlation was determined between bulb weight, leaf number and EC and bulblet number. All these results showed that grape hyacinth bulbs could maintain their normal development at low nutrient solution doses, thus saving on fertilizers.

    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2020) Kahraman, Ozgur
    The research was performed to determine the effect of planting depth on plant development characteristics in grape hyacinth growing ( Muscari armeniacum Leichtlin ex Baker). In the experiment, grape hyacinth bulbs with a circumference of 3.5 cm were used as plant material. Grape hyacinth bulbs were planted in the mixture of perlite + peat + cocopeat (1: 1: 1) at a depth of 1 cm (superficial planting), 4 cm (medium depth planting) and 7 cm (deep planting). After planting, bulbs were irrigated until the leaves formed, and then nutrient solution was applied. The experiment was designed as a randomized plot design with three replications with 10 bulbs each (pot). In the experiment, biometric measurements including emergence number, EC, pH, plant weight, bulb diameter, weight, bulblet number, adventitious root number, length, weight, leaf number, length, width and weight were determined. The data was applied to variance analysis (ANOVA) and Duncan multiple comparison test (p=0.05). According to statistical analysis; at the end of the 2nd week, the highest emergence rate (50%) from bulbs planted in superficial planting, and the highest plant weight (3.79 g) from bulbs planted in medium depth planting were obtained. The effect of planting depth on the other parameters was insignificant. The bulb diameter was 14.37-15.42 mm, the bulb weight was 1.79-2.11 g, the bulblet number was 1.00-1.40, the leaf length was 22.88-24.50 cm, the leaf width was 3.64-3.81 mm and adventitious root length was between 8.56-11.50 mm.

    This study was aimed to determine the possibility of reusing sewage sludge in the cultivation of Taurus snowdrop (Galanthus elwesii Hook. f.). Taurus snowdrop bulbs with a circumference of 4 cm were used as plant material in the experiment. Bulbs were planted in five different growing media, 100% soil, 25% sewage sludge+75% soil, 50% sewage sludge+50% soil, 75% sewage sludge+25% soil, and 100% sewage sludge. The bulb diameter ranged between 16.8 and 18.5 mm, and bulb weight varied between 2.74 g and 6.33 g. The greatest bulblet weight (2.17 g) and leaf thickness (0.90 mm) obtained was in 75% sewage sludge+25% soil mixture. The number of bulblets ranged from 1.0 to 1.33 piece/bulb. Leaf length was between 7.30 and 9.25 cm, and leaf width was 9.7 to 11.6 mm. The effects of growing media on pedicle length, pedicle diameter, and fruit diameter were not found to be significant. Pedicle lengths were between 4.39 and 6.38 cm, pedicle diameters ranged from 1.59 to 1.80 mm, and fruit diameters were between 4.40 and 7.40 mm. It was concluded based on the present findings that 75% sewage sludge+25% soil mixture could reliably be used as a growing media for Taurus snowdrop culture.

    (Univ Agricultural Sciences & Veterinary Medicine Bucharest, 2016) Kahraman, Ozgur; Akcal, Arda
    Leucojum aestivum L. (summer snowflakes) is one of the species permitted to export in a limited number from Turkey. 6-7 million summer snowflakes bulbs with more than 7.5 cm circumference are exported to the Netherlands, Denmark and USA. The bulbs obtained from propagation methods are only permitted to export. This study was conducted to enlarge the circumference of snowflakes bulb by using soilless culture techniques in different substrates such as sawdust, cocopeat and perlite+ peat in a short time in a part of unheated glasshouse which belongs to Eanakkale Onsekiz Mart University, Faculty of Agriculture, Department of Horticulture, 2014-2015. The study was established according to randomised plot design with 3 replications and each plot had 20 bulbs of Leucojum aestivum L. Some parameters like, bulb diameter, bulb height, bulb weight, stem diameter, stem and leaf weight, dry stem and leaf weight, leaf number, leaf length, leaf thickness, leaf width, root length, root weight, dry root weight and emerging ratio were determined. As a result of the study, substrates have a significant effect on bulb diameter, bulb height, bulb weight, stem and leaf weight, dry stem and leaf weight, leaf number, leaf length, leaf thickness, leaf width, root length, root weight, dry root weight and emerging ratio. However, there was no significant difference between substrate treatments for the stem diameter. The highest average value of bulb diameter (24.80 mm), bulb height (35.38 g) and bulb weight (10.29 g) were measured in perlite+ peat. While perlite+ peat gives the best result for leaf length (31.23 cm), the highest average value for root length (22.58 cm) were measured in cocopeat.
