Abstract
In the present work, two maize cultivars in which root meristem responded differently to root tip excision were used: in Interkras-375 MW, meristem opening was observed due to the activation of cell divisions in the quiescent center (QC); in Krasnodar-194 MW, the meristem remained closed. Excised root tips of Interkras MB-375 were shown to produce much more ethylene than excised root tips of Krasnodar-194 MW. The inhibitor of ethylene biosynthesis L-α-(2-amino-ethoxyvinyl)glycine-HCl (AVG) and inhibitors of ethylene action AgNO3 and 1-methyl-cyclopropene (MCP) prevented meristem opening in excised root tips of Intekras-375 MW. The obtained results allow us to conclude that ethylene plays an important role in the activation of cell divisions in the QC of excised root tips.
