Different root growth patterns in tomato seedlings grown hydroponically under an electric field [PDF]

open access: yes, 2013
Electric fields can determine changes at morphological and physiological levels in plants. In this study, seedlings of Solanum lycopersicum L., grown hydroponically in a floating system, were exposed to a DC 12.0 V m–1 electric field (EF).

Studies on root surface areas of the extracted teeth with periodontal problems.

open access: yesNihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 1987
骨吸収と歯根表面積との関係について調べる目的で今回の実験を行った。歯周疾患によって抜去した上下顎前歯部60本を用いて, 線維性付着部分と付着していない部分とに分け, 各々の歯根表面積と総歯根表面積を区分求積法により求めた。また, ポケットの深さと付着喪失面についても検索を行った。総表面積は, 上顎中切歯176.0 mm2, 側切歯172.8mm2, 犬歯218.5mm2, 下顎中切歯134.8mm2, 側切歯178.3mm2, 犬歯211.6mm2であった。付着部の割合は, 上顎中切歯24.0%, 側切歯24.9%, 犬歯6.9%, 下顎中切歯27.2%, 側切歯18.8%, 犬歯18.2%であった。ポケットは近遠心で深く, 付着喪失は唇舌側で多かった。上顎犬歯を除いて, 約80 ...

Varietal responses of root characteristics to low nitrogen application explain the differing nitrogen uptake and grain yield in two rice varieties

open access: yesFrontiers in Plant Science, 2023
Rice root characteristics are tightly associated with high-efficient nitrogen uptake. To understand the relationship of root plastic responses with nitrogen uptake when reducing nitrogen application for green rice production, a hydroponic experiment and

Estimating Surface Area of Soybean Root Systems [PDF]

open access: yes, 1969
A procedure for estimating the total root length, root surface, and root hair surface is described for greenhouse-grown soybeans. Data are presented on the extent of the root systems of 3-week and 14-week old soybeans. The possibility of correlating data
