The electrical potentials of Chara vulgaris
, 1936 An electric polarity corresponding to the morphological axis has been established in Obelia and other hydroids (3, 8), the Douglas fir (14), the onion root (10), the frog skin (12), the oat coleoptile (4, Wilks, loc. cit.) the bean plant (27) and other polar structures.

Determination of GA3 in Chara vulgaris by capillary electrophoresis system
Acta Physiologiae Plantarum, 1999Method for simultaneous measurement of gibberellic acid was applied using capillary zone electrophoresis. Gibberellic acid was identified in extracts of apical part of thallus of Chara vulgaris L. The amount of gibberellins measured on the basis of activity determined by the micro-drop bioassay (59.8 mg·kg−1; with gibberellic acid as a standard) was ...

Study on the phenology of Chara vulgaris in Xin’an Spring, north China
Frontiers of Biology in China: Selected Publications From Chinese Universities, 2009The phenology of Chara vulgaris was studied. The specimens were collected four times from April 2004 to January 2005 (one sampling per season). The water temperature, pH, dissolved oxygen, specific conductance, maximum width and maximum depth were monitored at every sampling time.

Farm pond restoration using Chara vulgaris vegetation
Hydrobiologia, 1979Four aged Madison County, New York farm ponds were selected to see if various treatments could be used to restore the water quality. One pond was untreated and used as a control; another pond was partially drained and exposed to the drying and oxidizing effects of the air over the fall and winter; the other two ponds were drained and the accumulated ...

Changes in ultrastructure of plasmodesmata during spermatogenesis in Chara vulgaris L.
Planta, 1985Two types of plasmodesmata are found within an antheridium of Chara vulgaris: open plasmodesmata filled with electron-transparent cytoplasm, and plugged plasmodesmata, filled with an osmiophilic dense substance. Open plasmodesmata occur only between cells synchronized completely in respect of their advancement in cell-cycle progression or ...

Inhibition of Chara vulgaris oospore germination by sulfidic sediments
Aquatic Botany, 2009Abstract The germinability of Chara vulgaris oospores collected from the sediments of four Ontario lakes varies considerably, ranging in germination percentage from 7% to 54%. Chemical analysis of the interstitial water of the sediments indicated that oospores with low germination occurred in lakes which have high acid volatile sulfides (H 2 S, FeS,
