Studies on the function of root traits and the genetic variation in these traits are often conducted under controlled conditions using individual potted plants. Little is known about root growth under field conditions and how root traits are affected by agronomic practices in particular sowing density. We hypothesized that with increasing sowing density, root length density (root length per soi...

OBJECTIVE To construct an adjusted nomogram for the echocardiographic screening of aortic root diameter in children with possible Marfan disease. DESIGN In 91 children (42 boys, 49 girls, age range 3.2 to 18.4 years) undergoing Marfan screening from 1983 until 1996, the diagnosis Marfan syndrome and any other aortic pathology was definitely ruled out. These served as a control population to s...

Root caries is not exclusive to older individuals. Any caries-prone patient having gum recession can develop root caries. However, the elderly are usually more vulnerable to root caries because of several conditions. First, older patients are more likely to experience gum recession. Gum recession exposes the root of the tooth, which is softer than the enamel-covered crown of the tooth. Conseque...

Root caries was once considered a disease for which the elderly population had their teeth extracted and replaced with removable prosthesis. [1] Approximately 38% of patients between the ages of 55 and 64 years have root caries , and 47% of those between 65 and 74 years have experienced root caries. [2] At present ,root caries is becoming a new area of focused research in dentistry ,as more peo...

Echocardiographic measurements of the left ventricular dimensions and wall thicknesses at end diastole and end systole, aortic root and left atrial dimensions, mitral valve E-F slope, left ventricular ejection fraction, percent fractional shortening of the left ventricular internal dimension, estimated left ventricular mass and percentage systolic thickening of the ventricular septum and left v...

Physiological traits associated with drought tolerance are useful as surrogate traits for drought tolerance. Information on the association of root traits and water use efficiency (WUE) and plant growth in sugarcane is rather limited. The objective of this study was to evaluate genotypic variation for root traits, WUE and growth characters of above ground parts of sugarcane. A 2 × 10 factorial ...

Scientists are currently debating the effects of mixing tree species for the complementary resource acquisition in forest ecosystems. In four unmanaged old-growth spruce-beech forests in strict nature reserves in southern Sweden and northern Germany we assessed forest structure and fine rooting profiles and traits (≤2 mm) by fine root sampling and the analysis of fine root morphology and biomas...
