ABSTRACT
The self-seeding of the seeds on plantations causes irreversible quantitative losses. Thus the knowledge of the variability of this unfavourable plant feature may contribute to decreasing the losses through the appropriate planning of harvest technology. For the evaluation of the carrot umbel susceptibility to shattering, a prototype vibration apparatus with the adjustment of the amplitude and frequency of vibrations was used. For investigations the main, first, and second umbels were taken into consideration. The seeds from the main umbels appeared to be most susceptible to self-seeding. To restrain the process of selfseeding during maturation, spraying of umbels with the glue substances was performed. Six different glues were applied to areas of carrot to reduce seed losses through shattering. Application of the BWD type glues increased seed yield by 30% and treatment had significant positive effect on seed germination. On the basis of these results a very favourable effect of that measure on the seeds preservation until harvest was confirmed.
