嚴(yán)禁灌水，很重要很重要的翻譯，要求懂有農(nóng)學(xué)、植物學(xué)學(xué)、遺傳育種學(xué)基礎(chǔ)等的高手來翻譯，多謝。 水稻休眠芽具有發(fā)育成完整水稻植株的潛能，是水稻再生繁殖的基礎(chǔ)。【目的】本研究為探索構(gòu)建一種快速獲得大量水稻再生植株的無性繁殖技術(shù)體系�！痉椒ā吭诔墒焓斋@后，截取特殊水稻材料(如雌性不育FS、雄性不育MS、多倍體和自交不親和等)以及常規(guī)稻、雜交稻(雜種F1)等植株莖節(jié)(含倒1～倒3節(jié)點休眠芽)，經(jīng)篩選出配比適宜的外源激素組合溶液浸泡處理后散播于育苗床上覆土培養(yǎng)，最終獲水稻再生植株。比較通過激素處理、無激素處理、直接移栽稻樁以及種子萌發(fā)所獲植株的各性狀及生理指標(biāo)差異�！窘Y(jié)果】不論是否通過激素處理,帶有節(jié)點休眠芽離體稻桿的再生效率都極顯著優(yōu)于模擬再生稻而直接移栽的稻樁，其出苗率及再生植株的葉綠素含量、葉面積、穗長、單穗谷粒數(shù)等都大幅度提高，差異極顯著。通過激素處理離體稻桿所獲植株的各性狀略好于無激素處理的再生植株，但與種子萌發(fā)的正常植株差異不顯著�！窘Y(jié)論】該研究初步建立了一套水稻休眠芽無性繁殖技術(shù)體系，能基本解決特殊材料的繁育以及雜交制種繁雜和成本高等難題，為豐富水稻無性繁殖技術(shù)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. |
