Studies Upon the Phonology of Rosie De Aries Onion Plants from the First Year of the Seeds Production Process and the Main Characteristics of the Parent Plants from 2007 until 2009 Year

The research was carried out in the period of 2007-2009 year, in the environmental conditions of SCDL Iernut. This spanned the duration of vegetation phases of plans from the experimental variants, since Ist year-parent plant phase, in three eras of sowing. The vegetation period of the parent plants (emergence- bulb maturity) was, as average on this three years of study, of: 125 days in the Ist age (1751 degrees C), 110 days in the IInd age (1821 degrees C) and 106 days in the IIIrd age (2130 degrees C). The studied characteristics were: weight of the bulb, the longitudinal diameter, the transversal diameter, the shape index and the height of the plant.
