In vitro regeneration and growth response of Kielmeyera coriacea shoots when affected by salts and sucrose concentrations. Cienc. Rural [online]. 1996, vol.26, n.1, pp. 57-61.

Trials were carried out to test sucrose and salt concentrations added to growth medium on regeneration and growth response of Kielmeyera coriacea shoots. The reduction and increase of sucrose of 30 and 45g/l, rerspectively, caused a decrease in total number of shoots. A higher shoots percentage of with more than 1.0cm, occurred on media with 30g/L of sucrose. The use of total force (1/1) and half strength (1/2) of MS salt proportioned a higher shoot ratio and growth.
