The adaptability potential of Lycium barbarum L., a species with significant health-promoting properties, in Bucharest’s area hasn’t been studied until now. This paper aims to present the evolution of the elements belonging to the juvenile plant’s architecture (number and length of shoots) and the stages of fructification (first floral buds and flowering sightings, number of flowers on shoots, fructification period, fruit quality) during the first two years from planting (2011-2012). Two phenotypes (V1 and V2) were planted and observed in the research field at U...A.M.V.’s Campus in Bucharest. At the end of 2011, newly-grown shoots per plant were between 10 and 40 for V1 and between 18 and 33 for V2. Their maximum number was 69 for V1 and 81 for V2. 2012’s values are 20 to 60 for V1, and 20 to 70 for V2. The maximum value for V1 is 108 and 85 for V2. At the end of 2011, the average length of the shoots was 10 to 50 cm for V1, with a maximum of 62 cm. For V2, these values were 20-80 cm, with a maximum of 99 cm. In 2012, V1’s new sprouts are 5 to 30 cm and V2’s are 9-40 cm long. In 2011, for V1, flower buds first appeared at the middle of June and flowering occurred at the end of the same month. V2 plants flowered in august, and bore far less flowers. Both phenotypes flowered until late November. The average number of flowers per shoot was between 5 and 40. Fruits set in at the end of June, less than a year’s time from cultivation. Production peaked in August and September. Fructification continued, for both phenotypes, until the end of November. V2 shrubs had fewer but bigger fruit, fructification started later and was less frequent. The average results at the quality tests were 16-20% dry substance per berry. The minimum value was 11%, the maximum 24%. Quality was slightly better for V2 fruit. In 2012, the first floral buds appeared on a V2 plant at the beginning of May and in a few days they were also seen on V1 plants. Days later, the first flowers appeared and in a week’s time, fruits also set in although they had not ripened yet. The average number of flowers and buds, per branch, is 5 to 50, with a maximum of 70. The significance of these results is that the studied phenotypes belonging to the Lycium barbarum L. species have shown a strong adaptability potential in Bucharest’s area.
