开花物候和林下草本植物的高度的测量的观察是在凉爽的温带落叶林，在那里的光的可用性是相对较低的，并通过一年中的波动显着，它是太冷，许多植物在冬季生长。4月至10月期间记录了91种。开花物种的数量作为日期的函数呈双峰分布。春季开花的植物和夏末秋初开花的植物各占40%左右。在春天开花的植物比在这个季节晚些时候开花的植物要小。春季开花的植物会在前一个生长季节产生花蕾，因为从地上部分出现到开花的时间是短暂的。有些种类在春季完成了主要的生活史事件，成为春季短命虫。这些种的小尺寸可能是由于前8个季节的芽形成和/或生长期短。相比之下，在夏末秋初开花的植物则很大。这些植物应该有相对较长的营养生长期，并在生长季节结束时使用当年生产的物质开花。较长的营养生长期往往会使植物变硬和/或变大。冷温带落叶林的气候和环境限制，将开花物候分为两个时期。[出版物摘要]
Observations of the flowering phenology and measurements of the heights of understory herbaceous plants were made in a cool temperate deciduous forest, where light availability is relatively low and fluctuates markedly through the year, and it is too cold for many plants to grow in winter. Ninety-one species were recorded between April and October. The number of flowering species as a function of date showed a bimodal distribution. The plants flowering in spring and those flowering from late summer to early autumn each accounted for about 40% of the number of species. The plants that flowered in spring were smaller than those that flowered later in the season. The spring-flowering plants would produce flower buds in the previous growing season, as the time from the appearance of the aerial part to flowering was transient. Some species completed their main life history events during the spring as spring ephemerals. The small sizes in these species may result from bud formation in the previous 8eason and/or the short period of growth. The plants that flowered in late summer and early autumn, by contrast, were large. These plants should have relatively long periods of vegetative growth and flower at the end of the growing season using matter produced in that year. A long vegetative growth period would tend to make plants firm and/or large. It was suggested that flowering phenology was separated into two periods by the climatic and environmental constraints of a cool temperate deciduous forest.[PUBLICATION ABSTRACT]
