严禁灌水，很重要很重要的翻译，要求懂有农学、植物学学、遗传育种学基础等的高手来翻译，多谢。 水稻休眠芽具有发育成完整水稻植株的潜能，是水稻再生繁殖的基础。【目的】本研究为探索构建一种快速获得大量水稻再生植株的无性繁殖技术体系。【方法】在成熟收获后，截取特殊水稻材料(如雌性不育FS、雄性不育MS、多倍体和自交不亲和等)以及常规稻、杂交稻(杂种F1)等植株茎节(含倒1～倒3节点休眠芽)，经筛选出配比适宜的外源激素组合溶液浸泡处理后散播于育苗床上覆土培养，最终获水稻再生植株。比较通过激素处理、无激素处理、直接移栽稻桩以及种子萌发所获植株的各性状及生理指标差异。【结果】不论是否通过激素处理,带有节点休眠芽离体稻杆的再生效率都极显著优于模拟再生稻而直接移栽的稻桩，其出苗率及再生植株的叶绿素含量、叶面积、穗长、单穗谷粒数等都大幅度提高，差异极显著。通过激素处理离体稻杆所获植株的各性状略好于无激素处理的再生植株，但与种子萌发的正常植株差异不显著。【结论】该研究初步建立了一套水稻休眠芽无性繁殖技术体系，能基本解决特殊材料的繁育以及杂交制种繁杂和成本高等难题，为丰富水稻无性繁殖技术提供了新思路。 The dormant buds of rice is the basis of the rice regeneration breeding, and it has the potential to develop into a complete plants.【Objective】The objective of this study was to explore and build a asexual reproduction technology system to quick access to a large number of regenerated rice plants.【Method】After mature harvest, we can the intercept the rice stems in vitro, including invertedto pour 3 nodes dormant buds,as materials which come from the special rice,such as female infertility FS, male sterility MS, polyploid and self-incompatibility, etc ,as well as conventional rice, hybrid rice (F1) .By the screened suitable ratio of exogenous hormone combination solution soaking,then spread in nursery bed , overburden nurture, and ultimately by the regeneration rice.【Result】The regeneration efficiency of the rice stems in vitro, Whether through the exogenous plant hormone treatment, was significantly better than directly transplanting rice pile which imitate ratooning rice, and the germination rate , chlorophyll content, leaf area, panicle length, single spike grain number of the regeneration plants are greatly improved, and the difference was very significant. Various traits of plants obtained by hormone treatment the rice stems in vitro was slightly better than non-hormone treated regenerated plants, but similar with the plants of seed germination.【Conclusion】This study initially established a rice asexual reproduction technology system.It can basically solve the problems like the breeding of some special materials, the complexity and high cost of hybrid seed production, and provides a new idea for the rich rice asexual propagation techniques. |

| The rice dormant bud is the basis for rice reproduction and regeneration, and it has the potential to develop into a complete plant.【Objective】The study aimed to explore and establish an asexual reproduction technology system to rapidly obtain a large number of regenerated rice plants.【Method】After harvest, we intercepted rice stems including dormant buds of the last three internodes from particular rice lines such as female infertility (FS), male sterility (MS), polyploid and self-incompatibility lines, as well as inbred rice and hybrid rice (F1). After soaking in solution with suitable hormone combination, spreading in nursery bed and overburden nurturing, regenerated rice plants were eventually obtained. The difference in various traits and physiological parameters were compared between hormone treatment, non-hormone treatment, directly transplanted rice stubble and seedlings. 【Result】Rice stems with dormant buds, regardless of hormone treatment, had significantly higher regeneration efficiency than directly transplanted rice stubbles which imitate ratooning rice. They also showed significantly higher germination rate, chlorophyll content, leaf area, panicle length and grains per panicle. Hormone treatment slightly improved the performance of the plants obtained from rice stems in vitro than non-hormone treated control, but similar with the plants from seed germination.【Conclusion】This study established a preliminary rice asexual reproduction technology system. It basically solves the difficult problems such as reproduction of some special materials, complexity and high cost in seed production of hybrid rice, and provides a new alternative to increase rice asexual propagation techniques. |
