Seeds were sown 8 - 10 cm deep in the first decade of April. Seed germination averaged 85% - 90%. The beginning of vegetation and leaf regrowth in Tashkent is observed in the second decade of April. The flowering phase was observed in the first decade of August and fruiting was noted in the first decade of September. Biometric indicators of the plant during the generative phase were revealed as follows: plant height 2.95 ± 0.22 m, generative shoot length 2.62 ± 0.24 m, number of leaves 46.5 ± 3.59 pcs., leaf length 10.11 ± 0.49 cm, root length 19.85 ± 0.88 cm, number of flowers 42.8 ± 2.37 pcs., flower diameter 4.82 ± 0.28 cm. Potential seed productivity (PSP) of the plant was noted 13.5 ± 0.5 pcs., real seed productivity (RSP) was 10.8 ± 0.44 pcs. And in turn, the seed productivity coefficient (SPC) amounted to 80.0% ± 1.31%. The primary results prove, according to the success of Ipomoea nil introduction, the noted indicators in Tashkent conditions.展开更多

Although there has been an increase in research aimed at promoting and managing the mental health of student-athletes, the mental well-being of coaches remains underexplored. Research indicates that the mental health profiles of coaches are similar to those of elite athletes [1] and should receive comparable attention. The introduction of Name, Image, and Likeness (NIL) legislation, along with the rise of the Transfer Portal in collegiate athletics, has presented student-athletes with new and unexpected options, which also bring novel challenges to coaches and potentially impact elite-level coaches’ mental health. This manuscript will identify three categories of stressors—performance, organizational, and self-related—that affect elite men’s college basketball coaches, highlighting how NIL and the Transfer Portal exacerbate those stressors and their impact on coaches’ mental health.展开更多
