In boreal ecosystems, phenological events display seasonal patterns. These patterns allow for the development of tissues during the short time window available for growth in cold climates. Primary and secondary growth, two expensive processes for plants, are supposedly modulated in time to optimize allocation of carbon to bud and woody tissues. We aimed to assess the phenology of primary and secondary meristems, testing their relationship over the closed black spruce stands of the commercially exploited forest region in Quebec, Canada.

区域范围内碳分配的时间梯度允许北方黑云杉的枝条生长和晚材形成

在北方生态系统中，物候事件显示出季节性模式。这些模式允许在寒冷气候下生长的短时间内组织发育。据推测，初级和次级生长是植物的两个昂贵过程，可以及时调节以优化碳对芽和木本组织的分配。我们旨在评估初级和次级分生组织的物候，测试它们在加拿大魁北克商业开发林区的封闭黑云杉林分上的关系。
