Adventitious Bud Production from Mature ,: Rejuvenation Associated with Female Strobili Formationimordia was obtained only when strobili were collected at about the time of meiosis. Adventitious buds arose mainly from the outside edges of strobili discs; some also arose from the cut surface of the ovuliferous scales. The frequency of adventitious bud formation varied from tree to tree, indicating intraspecific variation in bud formation.作者: ICLE 時(shí)間: 2025-3-27 21:25 作者: exceed 時(shí)間: 2025-3-27 23:02 作者: 統(tǒng)治人類 時(shí)間: 2025-3-28 05:35
