VEGETATIVE PROLIFERATIONS IN HERBAGE GRASSES

摘要: S.48 timothy plants were induced to form proliferating inflorescences by exposure 2–4 weeks of long days followed a return short days. Serial micro-dissections showed that the lemma enlarges resemble leaf but glumes, palea and all reproductive organs are also present perfectly farmed. At later stage vegetative shoot bearing several foliage leaves, axillary buds root initials is formed, presumably as continuation rachilla. The production proliferations insufficient photoperiods favourable for flowering discussed. Proliferations may occur spontaneously in many normally seed-setting grasses, number species this growth genetically fixed.
