Age estimation from dental radiographs is a non-destructive method to obtain information. The purpose of this investigation was to evaluate the possibility of age estimation from root diameter and root canal diameter of maxillary central incisors radiographs. 420 cone-beam computed tomography images of maxillary central incisors (210 males and 210 females) aged 15 to 84 years were chosen and cl...

to determine the most important traits affecting root yield and sugar content in monogerm germplasm of sugar beet, 75 monogerm f1 hybrids were evaluated in three separate experments conducted in randomized complete block desing (rcb) with four replications at abdo–al–rasoul research farm, karaj in 2004. root yield, root length, root diameter, crown height, crown diameter, sugar content, α–amino...

BACKGROUND AND AIMS Root diameter, especially apical diameter, plays an important role in root development and function. The variation in diameter between roots, and along roots, affects root structure and thus the root system's overall foraging performance. However, the effect of diameter variation on root elongation, branching and topological connections has not been examined systematically i...

Root diameter, a critical indicator of root physiological function, varies greatly among tree species, but the underlying mechanism of this high variability is unclear. Here, we sampled 50 tree species across tropical and temperate zones in China, and measured root morphological and anatomical traits along the first five branch orders in each species. Our objectives were (i) to reveal the relat...

Fine root respiration is a significant component of carbon cycling in forest ecosystems. Although fine roots differ functionally from coarse roots, these root types have been distinguished based on arbitrary diameter cut-offs (e.g., 2 or 5 mm). Fine root morphology is directly related to physiological function, but few attempts have been made to understand the relationships between morphology a...
