    Seasonal Changes in Cambial Activity in Rosa Canina
    (International Society for Horticultural Science, 2005) Türker, M.; Yörük, I.; Battal, P.; Kazankaya, A.; Tileklioǧlu, B.
    In the present study, cambial activity and the differentiation of phloem and xylem was studied in plants of Rosa canina L. growing in the Van province, Turkey. This species belongs to the dogroses, which are frequently harvested for their fruits (rose hips). The cambial zone was up to three cells wide. Cambial activity started in the third week of April. Summer wood formation was observed toward the end of May. The mean length and width of cambium cells during spring wood formation was 15.06 μm and 2.70 μm, respectively. During the summer wood formation, length and width was 14.16 μm and 3.16 μm, respectively. In spring wood, the lumen diameter of the biggest vessel was 54.41 μm, whereas the smallest one was 9.58 μm. The equivalent measurements in summer wood yielded 44.16 μm and 9.58 μm, respectively. The mean cell wall thickness of vessels and tracheids in spring wood was 1.87 μm and 3.33 μm, respectively, and 2.08 μm and 5.41 μm in summer wood. Cambial activity ceased toward the end of July. © ISHS 2005.

    Seasonal Changes of Endogenous Plant Hormones in Rosa Canina
    (International Society for Horticultural Science, 2005) Yörük, I.; Türker, M.; Battal, P.; Kazankaya, A.; Tileklioǧlu, B.
    Seasonal changes of gibberellins (GAs), the cytokinin trans-zeatin (t-Z), the auxin indole-3-acetic acid (IAA) and abscisic acid (ABA) in Rosa canina L. were analyzed by high performance liquid chromatography (HPLC). The concentration of GAs increased during the period of rapid growth in April and May, and coincided with the time of the increase in t-Z concentration. The concentration of IAA decreased slightly from January until March, increased strongly in April and then decreased again after the cessation of rapid growth. The concentration of ABA decreased steadily from January to May, followed by a slight increase which became most notable during the fruiting period, reaching a peak in January. © ISHS 2005.
