Allometry, root/shoot ratio and root architecture in understory saplings of deciduous dicotyledonous trees in central Japan
- Modelling Below- and Above-ground Biomass for Non-woody and Woody Plants. NIKLAS, KARL J. // Annals of Botany;Jan2005, Vol. 95 Issue 2, p315
â€¢ Background and Aims Intraspecific relationships between below- and above-ground biomass (MB and MA, respectively) have been studied extensively to evaluate environmental effects on growth and development at the level of the individual plant. However, no current theoretical model for this...
- branch:. Schlegel, Rolf H. J. // Encyclopedic Dictionary of Plant Breeding & Related Subjects;2003, p63
An encyclopedia entry for the term "branch," which refers to an axillary shoot or root, is presented.
- Root biomass of regenerating aspen (Populus tremuloides) stands of different densities in Alberta. DesRochers, Annie; Lieffers, Victor J. // Canadian Journal of Forest Research;Jun2001, Vol. 31 Issue 6, p1012
Examines the density of root biomass in regenerated aspen Populus tremuloides in Alberta. Proportion of root biomass to stand density and leaf area index; Height of parental root biomass; Ratio of root and shoot growth.
- Establishing Roots. Harris, Roger // American Nurseryman;5/15/2005, Vol. 201 Issue 10, p24
Focuses on the interpretation of the natural process of landscape gardening. Establishment of a tree in a landscape; Processes of wound compartmentalization and new root formation of plants; Development between the root system and emerging shoots. INSET: A compact issue.
- Accumulation of Pb and Cd and its Effect on Ca Distribution in Maize Seedlings (Zea Mays L.). Malkowski, E.; Kurtyka, R.; Kita, A.; Karcz, W. // Polish Journal of Environmental Studies;2005, Vol. 14 Issue 2, p203
In the present study the accumulation of Pb and Cd in maize seedlings (Zea mays L., cv. K33 x F2) and its effect on the content of Ca in their organs were investigated. The influence of both metals on dry weight yield was also studied. Concentrations of Pb, Cd and Ca were measured in 15 mm- long...
- 13Carbon Isotope Discrimination in Roots and Shoots of Major Weed Species of Southern U.S. Rice Fields and Its Potential Use for Analysis of Rice--Weed Root Interactions. Gealy, David R.; Gealy, Glenn S. // Weed Science;Oct-Dec2011, Vol. 59 Issue 4, p587
Assessing belowground plant interference in rice has been difficult in the past because intertwined weed and crop roots cannot be readily separated. A 13C discrimination method has been developed to assess distribution of intermixed roots of barnyardgrass and rice in field soils, but the...
- Relationships between xylem vessel characteristics, calculated axial hydraulic conductance and size-controlling capacity of peach rootstocks. Tombesi, Sergio; Johnson, R. Scott; Day, Kevin R.; DeJong, Theodore M. // Annals of Botany;Feb2010, Vol. 105 Issue 2, p327
Background and Aims: Previous studies indicate that the size-controlling capacity of peach rootstocks is associated with reductions of scion water potential during mid-day that are caused by the reduced hydraulic conductance of the rootstock. Thus, shoot growth appears to be reduced by decreases...
- The effect of light on nitrate uptake by wheat roots. Jinzhi Li; Jianming Gao; Ming Jiang // Acta Societatis Botanicorum Poloniae;2013, Vol. 82 Issue 3, p207
Illuminating shoots stimulates nitrate uptake by wheat (Triticum aestivum L. cv. 'EM18') roots. A method with a high time resolution (minutes), non-invasive technique, has enabled to measure the nitrate uptake time coarsely. The nitrate uptake by wheat roots increases in the light and decreases...
- ALTERNATIVE CLONAL PROPAGATION OF DRYOBALANOPS BECCARII AND D. RAPPA. Jong, L. K.; Sani, H. B. // Journal of Tropical Forest Science;Apr2012, Vol. 24 Issue 2, p275
Application of rooted cuttings derived from epicormic shoots from mature trees of Dryobalanops beccarii and D. rappa in current tree propagation and improvement programmes is suggested and discussed. Development of epicormic shoot indicated partial rejuvenation which was exhibited by...
