• The Effects of Growth Regulators and Apical Bud Removal on Growth, Flowering, and Corms Production of Two Gladiolus Varieties 

      Khalafalla, M. M.; Hegazi, M. A.; Eltarawy, A. M.; Magouz, M. R.; Elzaim, H. H.; Yndgaard, Flemming; Solberg, Svein Øivind (Peer reviewed; Journal article, 2022)
      Gladiolus is commonly propagated from corms. The multiplication rate of corms is low and to increase the propagation rate, we examined a combination of apical bud removal and the application of growth regulators. The ...
