观察了糖枫（Acer saccharum Marsh.）站在三个地下植物，Claytonia caroliniana，Erythronium americanum，Trillium erectum，对太阳辐射和温度的物候反应。这三个物种在地面部分被雪覆盖时开始发育。盛叶期和开花期的高峰期发生在枫树冠层发育之前。两个geophytes，Claytonia和Erythronium，完成了他们的生命周期之前，在树冠叶发育。生命周期似乎受到温度和太阳辐射的强烈影响。全文见JSTOR
Observations were made in a sugar maple (Acer saccharum Marsh.) stand on the phenological response of three geophytes, Claytonia caroliniana, Erythronium americanum, and Trillium erectum, to solar radiation and temperature. The three species started development when the ground was partly covered with snow. The peak of the leafing and flowering stages occurred prior to the lead development of the maple canopy. Two of the geophytes, Claytonia and Erythronium, completed their life cycle prior to leaf development in the canopy. The life cycles appear to be strongly influenced by temperature and solar radiation. See full-text article at JSTOR
