Influence of the orientation of uterine bulbs during planting on the seed yield of winter onion variety Ellan in a two-yield direct crop

The article presents the results on the use of paracuneal bulbs for re-harvesting seeds in a direct crop. The influence of the orientation of uterine bulbs during planting on the formation of paracuneal bulbs and seed productivity in the second year of vegetation was determined. The paracuneal bulbs were developing at the base of the flower shoots maintaining the same orientation as in the uterine bulbs when planted. Winter hardiness of paracuneal bulbs depended on orientation, just as with standard technology. Losses during the winter period ranged from 48% to 82%, increasing with an increase in the angle of deviation from the vertical position. The most vulnerable bulbs were the upside down. Paracuneal bulbs can be used to re-harvest seeds in a two-yield crop.
