目的研究三种不同生境土壤理化性质对一水硬石多态一年生植物砂角藻(ceratocarpus arenarius)一水硬石生产跨代可塑性的影响。方法对沙漠中3种蒸发形态的产生和植物的大小进行了评价。在S、盐漠(SD)和荒漠草原(DS)的土壤中,研究了来自土壤表层(a)和植被冠层中部(c)和上部(f)的1株植物的一水硬石产量和植株大小。结果0种植物在S中的散布单元形态数为(f)> c, > > a。这三种形态的植物在大小、质量和质量分配上都有所不同。对于f1植株(与F0相比),a:(c + f)在S(贫瘠土壤)中相同或增加,在DS(肥沃土壤)中降低;c (a + f)在S和DS中增加;S和DS中f:(a + c)降低。在SD中,来自a和c的f1植株的比率与S相同,但来自f的f1植株的比率与S和DS相同。结论土壤物理化学的差异导致一水硬铝石植物的大小、质量、质量分配和形态比例在不同世代间具有一定的灵活性。
AimsWe determined effects of soil from three habitats differing in physiochemical properties on transgenerational plasticity in diaspore production of the diaspore-polymorphic annualCeratocarpus arenarius.MethodsProduction of three disapore morphs and size of F0plants in a sand desert (S) were evaluated. F1plants from morphs at soil surface (a) and middle (c) and upper (f) parts of canopy of F0plants were grown in soil from S, salt desert (SD) and desert steppe (DS) and evaluated for diaspore production and plant size.ResultsNumber of dispersal unit morphs for F0plants in S was (f > c)> > a. Plants from all three morphs varied in size, mass and mass allocation. For F1plants (compared to F0), a:(c + f) was the same or increased in S (poor soil) and decreased in DS (good soil); c:(a + f) increased in S and DS; and f:(a + c) decreased in S and DS. In SD, ratios for F1plants from a and c were the same as those in S, but ratios for F1plants from f were the same as those in S and DS.ConclusionsDifferences in soil physiochemistry caused flexibility in plant size, mass and mass allocation and proportion of diaspore morphs across generations.
