Sprouting of the rhizome of Kohleria sp

The Kohleria sp species belongs to the Gesneriaceae family and produce subterranean organs. This organ is a stem, and it is enclosed by modified leaves which protect their buds. These modified leaves present great amount of starch. Small section of this organ sproutted without necessity of the whole organ. Sections of this organ with six modified leaves were submitted to different treatments: temperatures of 15, 20, 25, 30 and 35 ºC, in a condition with and without light and in reduced (1 mL) or high (12 mL) water level in the substract. The sprounting of the sections was influenced by these factors and rhizome sections presented very high resistence to drought since in this condition each section developed a new plant.
