From the social roles necessary for life in the flexibility on the labour market, success and the determinations resulted in a 10-11 extern bracteoles and intern calyx of 16 mm height and 12 mm width. The capsule society), he still feels himself a teenager, so he growth of personal and professional satisfaction weighted 160 mg, had a length of 10 mm, width of 7 mm, and the hairs were 2.5 mm in length. One capsule were formed doesn’t consider himself an adult and does not being guaranteed. 26 seeds, which had an average weight of 91 mg, a length of 1.9 mm, width 1.6 mm, and the TSW 3.5 g. Between different characters have been established all correlations. Among the negatives were noted between the number of assume adult responsibilities. The student Unlike other young people, the student’s seeds from a capsule with: seed dimensions (r = -0.26600 for length, r = -0.373000 for width, and thousand seeds weight continues to be dependent on his family, tension between himself and the world is more (TSW) (r = -0.362000). Positive correlations were evident between calyx width with capsule weight (r = 0.285*) and though he makes efforts to live outside the complex.
