The responses of Viola grayi seedlings to complete sand burial were experimentally assessed in this study. Approximately 10-month-old seedlings were buried in sand to a depth of 0, 1, 5, or 15 cm. The re-emerged seedlings were counted for 5 months, and the dry weights were compared. The results showed that shallow burial promoted the shoot development and total growth of seedlings. The dry weights of stems and leaves and the total dry weight of seedlings were higher in plants buried at depths of 1 and 5 cm than in unburied plants. The dry weight of roots did not differ among them. No seedlings buried at a 15-cm depth re-emerged. Most seedlings buried at 1- and 5-cm depths produced adventitious roots from below-ground stems. The tolerance and adaptive responses of V. grayi seedlings to sand accretion may contribute to their establishment in sand-accumulating habitats.

沙埋对沿海沙丘植物堇菜幼苗生长的影响：对沙积的耐受性和适应性反应
本研究通过实验评估了紫花地丁幼苗对完全沙埋的反应。将大约 10 个月大的幼苗埋入沙中，深度为 0、1、5 或 15 厘米。5个月后对重新出苗的幼苗进行计数，并比较干重。结果表明，浅埋促进了幼苗的地上部发育和总生长。埋深1、5 cm的植株茎叶干重和幼苗总干重均高于未埋深的植株。它们之间的根干重没有差异。埋深15厘米的幼苗没有再出现。大多数埋在 1 厘米和 5 厘米深的幼苗从地下茎中产生不定根。V. Grayi的耐受性和适应性反应幼苗积沙可能有助于它们在积沙生境中建立。
