RESULTS AND DISCUSSION
The effects of SA on root growth and production of
oxyprotostemonine, stemocurtisine and stemocurtisinol:
A comparison was made between cultures treated with SA
and controlled cultures of the root growth and
oxyprotostemonine, stemocurtisine and stemocurtisinol
production. SA was added on the first day of the culture
period and the effects were observed at 16th week (4
months). Figure 1 shows the effects of SA on root growth.
In this experiment, salicylic acid had a negative effect on
root growth. All concentration of SA slightly decreased
root growth compared to the control (Table 1) and
stimulation root browning.
