“…In tulip bulbs there were isolated and characterized 5lipoxygenase (Reddanna et al, 1988) and 9-lipoxygenase (Grechkin et al, 2000). Many studies concerning metabolic processes and changes in levels of some substances possibly associated with cooled tulip bulbs have been published, including changes in polyamine contents (Kollöffel et al, 1992), redistribution of organic nitrogen and carbon (Ohyama et al, 1988;Lambrechts et al, 1992), changes in the content of amino acids in anthers from tulip bulbs (Lukaszewska et al, 1989;Tonecki and Gorin, 1990), starch content and αamylase activity (Gorin and Heidema, 1985;Heidema et al, 1986), chalcones content (Franssen and Kersten, 1992), carbohydrate content (Lambrechts et al, 1994) and invertase activity (Lambrechts and Kollöffel, 1993). Physiological role of lipid metabolism in dormancy and dormancy release in tulip bulbs is unknown.…”

Lipid peroxides and their conversion products are active in various physiological processes in growth and development. Physiological role of lipid metabolism in dormancy and dormancy release in tulip bulbs is unknown. We found in tulip leaves high level of free and bound C18:3 and C18:2 acids and small amounts of C18:1, C18:0, C16:1, C16:0, C14:0, C12:0 acids. In our studies the level of lipid peroxides was determined in leaves, anthers and basal plate of uncooled and cooled tulip bulbs 'Apeldoorn' as a concentration of MDA, using a modified thiobarbituric acid-malondialdehyde (TBA-MDA) assay. The MDA level was lower in anthers than in leaves and basal plate. During 8 weeks of bulbs storage no changes in lipid peroxidation levels were found, with the exception of 3 rd leaf at which a decrease was noted. After 8 weeks of bulbs storage, lipid peroxidation increased in all samples. However, there were no differences in MDA levels between samples from uncooled and cooled bulbs. It seems that in tulip bulbs lipid peroxidation was independent to temperature of bulbs storage. These results indicated that lipid peroxidation is probable not involved in dormancy and dormancy release in tulip bulbs.

“…An assay to determine if a tulip cultivar has received a proper cold treatment would be desirable. Previous studies have been conducted on physiological changes occurring in carbohydrate and amino acid metabolism (Gorin et al, 1990;Gorin and Heidema, 1985;Heidema et al, 1985;Lambrechts et al, 1992;Lukaszewska et al, 1989;Tonecki and Gorin, 1990) and chalcone content (Franssen and Kersten, 1992). None of these has provided a satisfactory assay.…”

To find a suitable indicator for properly cold-treated tulip bulbs (Tulipa gesneriana L. cv. Apeldoorn), the content of the endogenous free gibberellins (GAs) GA1, GA4, GA9, GA24, and GA34 was investigated. GA levels were measured in the shoots and basal plates at the start and at the end of a complete cold treatment of 12 weeks at 5 °C by combined gas chromatography–mass spectrometry using deuterated internal standards. Bulbs stored at 17 °C for 12 weeks served as controls and the experiment was repeated three times. Before the cold treatment, GA1 and GA4 were the major occurring GAs in the shoots. After 12 weeks, GA4 was the main GA component and the levels of GA1 were low in precooled and nonprecooled bulb shoots. The levels of GA4, GA9, GA24, and GA34 in precooled and nonprecooled bulb shoots and basal plates were similar. Hence, no direct correlation between cold-stimulated growth and a change in the endogenous GA status in shoots or basal plates was determined during the cold treatment. The free GA content in shoots or basal plates at the end of bulb storage cannot be used as a marker in a test for properly cold-treated `Apeldoorn' tulip bulbs.

“…The growth of these developing storage organs is also crucial to the flowering capacity of plants (Khodorova and Boitel-Conti, 2013). However, varying concentrations of sucrose and precooling applications can be very useful in the development of a plant or microbulblets from bulb explants of hyacinthus, tulips, lilium and glodiole (Takayama and Misawa, 1980;Halmer and Bewley, 1982;Heidema et al, 1985;Lian et al, 2003;Kizil et al, 2016).…”

In this study the effects of different sucrose concentrations, and the combinations of jasmonic acid (JA) with auxins (IAA or NAA) or with cytokinin (2iP) on the bulb induction and rooting of in vitro plantlets of Hyacinthus orientalis subsp. chionophyllus Wendelbo, which is endemic in Turkey, were investigated. The effect of four different sucrose concentrations (30, 45, 60 and 90 g L-1) on bulb formation in tissue culture was investigated. These plantlets were cultured on MS medium supplemented with several concentrations and combinations of JA (0.0, 1.0, 2.0 mg L-1) and 2iP (0.0, 0.25 and 0.50 mg L-1), IAA or NAA (0.5, 1.0 mg L-1). In JA- 2iP treatment, the highest number of bulblets (13.7 number/explant) was obtained by the combinations of JA 1.0 mg L-1 + 2iP 0.25 mg L-1. Also, the largest bulblets with the mean diameter of 7.9 mm were found on MS medium supplemented with JA 2.0 mg L-1. In JA – Auxin treatment, the mean root number per bulblet was highest (17.9 number/explant) and root formation rate was maximum (81.14%) on MS medium supplemented with IAA 1.0 mg L-1 + JA 2.0 mg L-1.
