kn-title=Fasciation in Strawberry Floral Organs and Possible Implications for Floral Transition

kn-abstract=Fasciation in strawberry is characterized by an enlarged and flattened receptacle, clustering of flowers, and altered inflorescence architecture. However, the developmental process of fasciated flowers remains obscure. In this study, the fasciation incidence and developmental process in the primary fruit and inflorescence architecture were evaluated and compared for the non-susceptible cultivars, ‘Nyoho’ and ‘Sagahonoka’ and one of the most susceptible cultivars, ‘Ai-Berry’. The severity and frequency of flower and inflorescence fasciation was clearly greater in the vigorously growing large plants of ‘Ai-Berry’ compared to small plants and large plants of the other two cultivars. In ‘Ai-Berry’, the deformation of the large shoot apical meristem (SAM) into an oval shape was the initial symptom observed before and during floral transition. Such oval-shaped SAMs often differentiated two or more leaf primordia almost at the same time, which then developed into divided multiple vegetative SAMs before floral transition and linearly-fasciated SAMs during floral transition, respectively. The development of fasciation symptoms was observed after downregulation of FaTFL1. Although inflorescence or receptacle fasciation could be controlled when early and rapid floral induction was achieved by intermittent low-temperature treatment, severe fasciation was observed in late-flowered plants which were either not responsive or not subjected to this treatment. These results indicate that fasciation of floral organs may be triggered and develop during floral transition and that temperature fluctuations around boundary values between floral inhibition to induction may cause a half-finished or slowly processed floral transition and finally result in severe fasciation in vigorously growing ‘Ai-Berry’ plants.

kn-abstract=　My research interest is in the physiology and ecology of ornamental plants. Here, I introduce my research subjects on the stabilization of flower color and cut flower longevity. Seasonal color change of dahlia (Dahlia variabilis) is studied as practical study for improving the stable dahlia cut flower production during autumn and winter. The results obtained from pigment analysis and clone selection are presented. Research on cut flower longevity is presented from two aspects. Firstly, study on the structure of conductive tissues that contribute to water transport is presented. Secondly, study on the floral organs that contribute to transpiration from cut flowers is presented.
