一种兰花种子的保存及育苗方法

本发明公开了一种兰花种子的保存及育苗 方法。本发明通过采收发育基本成熟而未开裂的 兰花蒴果，消毒，无菌条件下将蒴果内的种子转 移至灭菌的离心管内，盖上离心管盖并用透气膜 密封，于4-6℃条件下保存；待需要育苗时，将保 存的种子取出，室温下放置至离心管内达到室温 后，用无菌水将种子制作成种子悬浮液，然后取 种子悬浮液均匀接种于一次成苗培养基上，一次 培养成苗。本发明将兰花种子在4-6℃条件下贮 存5年后，仍然保持较高的萌发率(75 .6％)，而且 要求的设施条件简单、廉价、无污染且保存容量 巨大；经本方法存放的种子不需再经表面消毒处 理，采用非共生萌发技术进行无菌播种，可一次 培养成苗。This invention discloses a method for preservation and seedling cultivation of orchid seeds. The present invention harvests orchid capsules that have basically matured but have not yet dehisced, disinfects them, transfers the seeds inside the capsules to sterilized centrifuge tubes under aseptic conditions, covers the tube caps and seals them with gas-permeable membranes, and stores them at 4–6 °C. When seedling cultivation is required, retrieve the stored seeds, allow them to equilibrate to room temperature within the centrifuge tubes, prepare a seed suspension using sterile water, then uniformly inoculate the seed suspension onto a one-step seedling-forming medium, and culture to obtain fully developed seedlings in a single step. After 5 years of storage at 4–6 °C, the orchid seeds of this invention still retain a high germination rate (75.6%). Additionally, this method demands simple, low-cost, pollution-free facilities and offers a large storage capacity. Seeds stored via this method do not require additional surface disinfection; aseptic sowing using asymbiotic germination technology allows for one-step seedling formation through culture.
