昆蟲不育 的英文怎麼說
中文拼音 [kūnchóngbùyù]
昆蟲不育
英文
insect sterile-
The degradation of chitin by chitinase was vital step in the life cycle of insects because insects undergo periodic ecdysis and metamorphosis
幾丁質代謝隨昆蟲不同生長發育階段而變化並保持相對的穩定,對昆蟲的正常的生長發育是至關重要的。This paper firstly focused on and evaluated the pollination characteristics of c. praecox, in half - natural habitat of nanjing. we investigated flowering phenology, flowering patten, pollen viability, stigma receptibility, species of visitors, visiting rate of visitors and their foraging behavior. and we also investigated its breeding system, including pollen - ovule ratio ( p / 0 ), out - crossing index ( oci ), pollen grains deposited in stigmas, pollen germination rate and seed set rate with different treatments, from 2002 to 2004
試驗分別在2002 - 2003年和2003 - 2004年冬季進行,研究內容包括:花期物候觀察、花部形態觀察和統計、雌雄配子體功能測定、訪問昆蟲種類、訪問行為、訪花頻率和效率;同時對蠟梅繁育系統進行了檢測,檢測內容包括花粉胚珠比( p / 0 ) 、雜交指數( oci )及不同處理花粉萌發率及結實率檢測等等,同時還進行了蠟梅與亮葉蠟梅傳粉過程比較。For example, the larval body length and morphological characteristics of most necrophagous flies is difficult to be discerned as larvae are at the post - feeding stage, easily resulting in the determination of pmi
但這些指標有時難以真實反映昆蟲所處的生長發育階段,如蠅類離食期幼蟲的體長和形態變化均不明顯,易造成推斷誤差。The results not only provide evidences for the study of early embryonic development mechanism in silkworm, but also give clues for the study of insects diversity
這一結果不但可以為家蠶胚胎發育調控機制的分子水平研究提供重要參考,也可為昆蟲分化多樣性的分了機制研究提供線索。分享友人
