Abstract
Marjoram seeds were soaked in Gibrescol solution (GA3), matriconditioned with MicroCel-E (MCE), and osmoconditioned in polyethylene glycol solution (PEG). The treated seeds and control ones were either dressed with fungicide or sown without it.
In order to investigate the effect of the applied treatments on the marjoram herb yield, content and composition of essential oil and oil yield, field experiments were conducted in two regions of Poland (Warsaw and Krakow). Transplants were grown in the greenhouse.
Each tested method of presowing treatment increased the seed vigour and the highest improvement was noted with MCE and followed by PEG and GA3, respectively.
Fungicide application did not cause positive effects.
That was also confirmed with the results of field experiments where fungicide applying either showed no significant differences (Krakow) or even decreased the yield of marjoram herb and oil (Warsaw). The advantageous effect of presowing seed conditioning and treating with GA3 on the marjoram yield was observed in both experimental locations, eventhough its degree was different.
Tested methods of seed treatment did not change marjoram oil composition considerably.
