selfing 中文意思是什麼

selfing 解釋
自花授精
  1. 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。
  2. It revealed that these two transformants were heterozygote, and the foreign gene inserted just to on locus in the plant genome. as the observed ratio of progeny of two transformants which on selfing was 3 : 1, it was proved to be heterozygote for two transformants

    其中2棵抗性株自交後代的遺傳分析表明,真空滲入法所得的轉化株為雜合體,且其分離比符合3 : 1的單基因分離規律。
  3. Selfing heterozygotes halves the heterozygosity, and thus outbreeding maintains heterozygosity and produces a more adaptable population

    自交雜合子有一半雜合性,因此遠系繁殖可以產生適應能量更強的種群。
  4. Selfing is inhibited by genetic self incompatibility and also by the fact that within a single flower the stigma is receptive before the anthes are ready to shed pollen.

    由於遺傳上的自交不親和性以及花中柱頭只能在花粉準備撒粉以前接受花粉,因而防止了自交。
  5. Homozygous races do not segregate on selfing.

    自體受精不能分離純合的生理小種。
  6. F2 the second filial generation, obtained by crossing or selfing within the f1 generation

    子二代(雜種二代) : ,通過子一代內部的雜交或自交獲得。
  7. The seed - set by legitimate union is higher than that by illegitimate union. as to pollination effect, the seed - set of p. cicutarrifolia usually depends on pollinator visiting, but selfing will be favored in the stressed environment

    其同型花授粉率高,異型花授粉率低,而毛茛葉報春在正常情況下,以蟲媒授粉為主,當環境受到協迫時,也可進行自花授粉。
  8. On selfing or crossing heterozygotes some double recessives may appear, giving viable offspring

    在自交或雜交產生的雜合子中雙隱性性狀可以表現出來並產生可育後代。
  9. Most seed orchard theory is based on the assumption that panmixis will occur and that selfing will not be a serious problem.

    大多數關于種子園理論,是以假定能發生隨機交配和自花受精而不會成為嚴重問題為依據的。
