Bound character meaning "to cultivate/nurture", central to 培养 (péiyǎng) - to develop or foster (talent, habits, people): 培养兴趣 (péiyǎng xìngqù) - to cultivate an interest.
培训 (péixùn) refers to professional/skills training, and doubles as a noun: 培训班 (péixùnbān) - training class.
培育 (péiyù) and 栽培 (zāipéi) both extend the "cultivate" sense to plants, and figuratively to mentoring people.
培 rarely appears as a standalone verb - it needs one of these companions.
