Fine root morphological traits regulate the belowground resource acquisition strategies of trees. Therefore, investigating genotypic variations isolated from environmental variations within tree species helps in understanding how genotypic backgrounds affect intragenerational tree acclimation to the growing environment. Thus, this study aimed to cl...
Aims
Fine root morphological traits regulate the belowground resource acquisition strategies of trees. However, genotypic variations isolated from environmental variations within tree species remain unclear. Thus, this study aimed to clarify the effects of genotypic variations on the fine root morphology of three types of Japanese cedar (Cryptomeri...
To elucidate the physiological and morphological factors underlying intraspecific variation in growth rate, we examined the variation in leaf and whole‐tree traits for three geographical variations of ca. 45‐year‐old Japanese cedar ( Cryptomeria japonica D. Don) with contrasting heights and radial growth in a common garden. Traits that reflect leaf...
Fine root phenology is controlled by complex mechanisms associated with aboveground phenological events and environmental conditions, and therefore, elucidating fine root responses to changing environments remains difficult without considering the dynamics within and among years. This study evaluated the response of fine root growth at variable tim...
Masting, a large interannual variation of reproductive investment spatially synchronized within perennial plants, is an important factor for understanding the use and storage of carbon and nutrient resources in various forest ecosystems. Fine roots play essential roles in water and nutrient uptake but also consume a large amount of net primary prod...

Key Message
Fine roots with thick diameter preferentially elongated into disturbed soil space, indicating positive invasion of pioneer roots that recolonize distal root systems.
Abstract
Fine roots and their morphological traits are related to below-ground resource dynamics at physiological and ecological levels. Established approaches for investi...
AimsFine root production in ecosystems has been estimated mainly by excavation methods that cause soil disturbance. In this study, patterns of fine root dynamics following soil disturbance were monitored for multiple years and were analyzed quantitatively by applying a root scanner method that allows continuous observations. Methods
Eleven scanners...
