For both the control and the treated containers, the relative root elongation (RRE) was calculated ((root size after AlCl3 - root size before AlCl3 treatment) × 100)/ root size before AlCl3 treatment).
The uptake of nitrogen was described by a first-order equation in which the uptake parameter combined the effects of root size and the uptake per unit root size.
Apart from plant life span, only plant height and seed size were related to root size in the adult plants.
The cooling and heating time was significantly (P < 0.05) affected by high air velocity and sweet potato root size.
The initial test results were positive and indicated that this technique could be used to reliably determine tree root size and depth under pavements with minimal error.
Let us now see how to solve the original problem, in which we would like to have not only minimum root size, but also precisely M keys in the root.
The problem is the following: given a sequence E, and limits (L1,L2), give an efficient algorithm for determining a weak B-tree that has height two, precisely M keys in the root and minimum root size.
Humic substances (HS) have been widely recognized as a plant growth promoter mainly by changes on root architecture and growth dynamics, which result in increased root size, branching and/or greater density of root hair with larger surface area.
There is no evidence of the existence of significant differences (p < 0.05) between treatments and control, according to the values obtained for root size as well as aerial dry weight and root dry matter.
For all seed lots combined, the mean total root length (all root size classes combined) for 1-year-old trees was 10.1 m increasing to 204 m by year 4 (Additional files 8 and 9).
The reasons for resorption were that block Auto-FDT was placed with natural root size and shape into extracted sites without overcorrection and space maintained improperly with or without resorbable membrane.
