In the tetraploid Tulipa sylvestris we found larger and heavier seeds that germinated around 28 days earlier than those of the diploid ancestor Tulipa pumila. The faster germination of the tetraploid species is linked to the faster growth of embryos, which reached their final length much earlier than the embryos of the diploid species. In conclusion, we argue a cautionary approach when dealing with comparative studies on ploidy level and germination to avoid misinterpretation of results when set against the natural conditions.

具有不同倍性水平的两种密切相关的郁金香物种显示出不同的发芽率

在四倍体郁金香我们发现比二倍体祖先早约 28 天发芽的更大更重的种子郁金香. 四倍体物种的更快发芽与胚胎的更快生长有关，胚胎的最终长度比二倍体物种的胚胎早得多。总之，我们在处理倍性水平和发芽的比较研究时提出了一种谨慎的方法，以避免在针对自然条件时对结果的误解。
