Ověřování účinku fytohormonů na diferenciaci kořenů u dřevitých řízků podnoží peckovin
Ambrosová, Lýdie
This diploma thesis deals with the examination of impacts of phytohormones on rooting of hardwood cuttings of rootstocks. The goal of the thesis is an evaluation of chosen stimulators and rootstocks. There are examined 1% stimulators based on NAA, NAA in combination with brassinosteroids, IAA, IBA, IBA as powder and non-treated control in this thesis. The evaluated rootstocks are VVA-1, AP-1, MY-KL-A, Ishtara and PS-1. The best results reach stimulators based on IBA and IAA (57--58 %), generally all examined rootstocks of cuttings treated by stimulators achieves better rooting rates, more than 50 % (only variants with brassinosteroids do not take root at all). Control without any treatment reaches 43 %. The best rooting rates have rootstocks AP-1 (58 %), VVA-1 and MY-KL-A (55--56 %), worse rooting rates have rootstocks PS-1 and Ishtara (both 26 %).
