  12. The study on the characteristics of development and seed setting of different spikelet and floret positions was important for the realization of big - spike - cultural - goal with more spikelets and grains. with both the winter type ( wv ) and spring type ( sv ) varieties sown at different dates, it was found that the greater seed setting capacity of spikelets resulted in more grain number of spike. the trend of differences in grain weight per spikelet between the different sowing dates and varieties was similar to that of grain number. the correlation between the average grain weight of middle spikelets and lower spikelets and the grain weight per spike was highly significant. the environmental changes resulted from different sowing dates mainly effected the middle spikelets development, even though the differences between wv and sv were represented in every spikelet positions. the grain weight on the second floret position was most sensitive to the development status of wheat plant and environmental changes, and could represent the yielid potential of the whole spikelet. the results showed that the enhancement of seed setting of the middle spikelets ( from 5th to 15th ) and the grain development from the first to third floret positions was a key to realize big - spike and grain

  13. Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants

    文摘:生物入侵是不均衡世界的一個永恆話題,尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的,但另外一些則有著嚴重的後果,會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式,概述了它們對遺傳多樣和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣式樣來推斷入侵途徑,來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法行了總結,這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變(瓶頸效應及種群擴張) .最後,我們以歐洲櫟癭蜂(膜翅目,癭蜂科,癭蜂族)一系列入侵的數據為例對一些方法行了說明.從500 10000年的時間尺度上,多態的等位酶位點上等位基因頻率的數據表明: 1 )遺傳多樣沿入侵路線呈不斷下降的勢,支持了冰河期避難所作為遺傳多樣中心的作用; 2 )入侵地區的種群與該物種原產地的種群相比,遺傳上的分更為強烈.這種種群結構在空間上的變可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變的反映
