In normal greenhouse condition, coda - transgenic wheat lines ( to ) had the same plant morphorlogy and pollen i2 - ki staining rate as untransformed control plant. after treating with 300 mm of 5 - fc, however, changes in configurations of spikelet, floret and anther have been observed in the transgenic lines but not in the control, and 50 % gus - positive lines displayed outside - opened glume, abnormal stamen, smaller and thinner anther, shorter filament, and failure of selfing. in parts of 5 - fc - treated transgenic lines, the pollen staining rate by i2 - ki was much lower than that of untransformed control
溫室栽培的轉基因小麥苗( t _ 0 )未噴5 - fc處理時植株外部形態和花粉碘-碘化鉀染色的著色率與未轉基因的對照沒有差異;用300mm的5 - fc處理后,發現有50 gus陽性株系與對照有明顯的區別,表現為小穗穎殼外張,花絲短縮,花藥發育不良,較小、黃白色且花粉粒少,自花不授粉,無外來花粉授粉則不結實。Abstract : the main characters and seed set of bc1 , bc2 , bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields
文摘:研究了雜交稻花粉對母本不育系回交後代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現,分析了不育系中出現大量自交結實株的原因,討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響,指出「同質恢」對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。Studies on dynamics of boron and magnesium nutrients during fruit development of parthenocarpy and self - pollinated citrus cultivars
單性結實和自花授粉結實柑橘果實發育中硼鎂營養動態的研究Changes in concentrations of boron ( b ) and magnesium ( mg ) in the ovary ( fruitlet ), rind and pulp of fruit were investigated throughout fruit development of parthenocarpic kamei satsuma mandarin ( citrus unshiu marc. ) and self - pollinated egan 1 tangerine ( c. reticulata blanco ). the results showed as follows : 1 ) b concentrations in the ovary of kamei were at high levels before flowering and at full bloom, and decreased after flowering, whereas that of egan 1 was relatively low at full bloom, thereafter significantly increased. no significant differences were observed in mg changes in the ovary ( fruitlet ) between the two cultivars, which presented decreasing trends after flowering. 2 ) minor changes of b concentrations in the rind of the two cultivars were detected, remarkable changes were found for b in the pulp, which came to the peak values during the stage of fruit enlargement. mg concentrations were relatively high in the rind and pulp of the two cultivars during early fruit development, and presented obviously declining trends during the middle and late stage of fruit development
以單性結實的龜井溫州蜜柑和自花授粉結實的鄂柑1號橘為試材,對整個果實發育期的子房(幼果) 、果皮和果肉的硼鎂含量變化進行了測定.結果表明: 1 )龜井花前至花期子房硼含量就已較高,花後下降;而鄂柑1號花期子房硼含量相對較低,花後有一顯著上升;兩品種子房(幼果)鎂含量變化無明顯差異,花后均趨下降. 2 )兩品種果皮硼含量變幅較小,而果肉硼含量變幅相對較大,且均在果實膨大期出現明顯的上升高峰;兩品種果皮和果肉鎂含量在果實發育前期均相對較高,在果實發育的中後期則趨明顯下降( 3 ) the value of p / 0 of c. praecox is 2847. 3 + 1125. 0, and the total value of oci is 3. with the above results, pollen germination rate and seed set rate, all shows that breeding system of c. praecox is facultative hybridization. the breeding system of c. nitens is similar to c. praecox, but it is higher in proportion of self - pollination than that of c. praecox
( 3 )蠟梅p / 0值為2847 . 3 1125 . 0 、 oci累計分值等於3 ,與不同處理的花粉萌發率和結實率的結果一樣,都顯示蠟梅繁育系統為兼性異交類型;亮葉蠟梅繁育系統同蠟梅相似,但亮葉蠟梅的自交比例相對較高The topography and the nano - mechanical property of the sample before and after self - assembly was characterized by afm, and the factor attributed to the change was analyzed. based on the above conclusion, the nano - mechanical property of the sample fabricated with the technology based on the scratch of afm microprobe combining traditional self - assembly method was analyzed. it was proved that this method could carry out controllable self - assembly on silicon surface ; finally, the nano - mechanical property of the sample fabricated with the technology based on the cutting of diamond tool was measured, and this method was proved to be a quick and convenient mean that could carry out controllable self - assembly on silicon surface according to the nano - mechanical property of the samples fabricated by the two method before
之後利用原子力顯微鏡對組裝前後的樣品進行了表面形貌和納米機械性能的表徵,分析了可能導致其變化的原因;藉助所得的結論,對基於原子力顯微鏡微探針的刻劃與傳統自組裝方法相結合的自組裝加工技術所制備的樣品進行了納米機械性能的分析,證明這種方法能夠實現硅基底上的可控自組裝;最後,對基於金剛石刀具切削的自組裝加工技術所制備樣品的納米機械性能進行了檢測,通過和前兩種方法制備的自組裝結構的納米機械性能進行對照,證明這種方法可以方便快捷的實現硅基底上的可控自組裝,從而實現「割草種花」的構想。4. according to the especial properties and function requirement of edm and order system of moving controller, relative function modules are developed in dll form. the self - design language transfer module of motion controller realizes tow dimension cutter compensation and three dimension globular - cutter compensation and completes iso code program to satisfy the requirement of edm
4 、依據電火花加工的特殊性和功能需要,結合運動控制器的指令系統,以dll的方式,開發出相應的功能模塊,並通過自行設計的運動控制卡語言轉換模塊,實現了二維c刀補和三維球形刀補,很好地完成了利用iso代碼編程以實現電火花加工的要求。Studies on dynamics of calcium and potassium during fruit development of parthenocarpic and self - pollinated citrus varieties
