外来花粉 meaning in Chinese
foreign pollen
Examples
- 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
温室栽培的转基因小麦苗( t _ 0 )未喷5 - fc处理时植株外部形态和花粉碘-碘化钾染色的着色率与未转基因的对照没有差异；用300mm的5 - fc处理后，发现有50 gus阳性株系与对照有明显的区别，表现为小穗颖壳外张，花丝短缩，花药发育不良，较小、黄白色且花粉粒少，自花不授粉，无外来花粉授粉则不结实。
