The effects o f thidiazuron (TDZ) on adventitious shoot bud formation from leaf and peti­ ole explants excised from in-vitro-grown plantlets o f a begonia were tested by a two-step procedure: a short exposure (5 to 120 min) to 40 pM TDZ in liquid MS medium followed by culture on agar-solidified MS medium without growth regulators. Exposure of explains for five min to TDZ induced bud formation, ...

The polychaete Sabellaria alveolata (Linnaeus, 1767) is an important ecosystem engineer building reef structures which add to the topographic complexity in colonized areas. In Europe, the most extensive reef formation is located in the Bay of Mont-Saint-Michel (France). Since 2006, Sabellaria bio-constructions have developed on hard substrates along the west coast of the Cotentin Peninsula betw...

Exposure to UV light can cause damage DNA strands, but also be used as a disinfectant. This study sought investigate how UV-C affected the growth rate of Begonia dregei and arching. The plants were split into 4 different treatment groups, with each group containing one Each was treated certain amount time using box before they allowed grow under ideal conditions. Once done treatment, grown in i...
