EFFECT OF SALICYLATES ON AFRICAN VIOLET

摘要

Aqueous solutions of 10~(-6) to 10~(-10) M concentrations of salicylic acid were sprayed on ornamental vitroplants of African violet grown under greenhouse conditions to estimate its effect on the bioproductivity of the plant. These solutions were sprayed on the shoots of the plant on three occasions, 21, 28 and 35 days after being potted. Results showed that the best treatment was that of 10~(-10) M where significant results were found in the growth development pattern and in the number of leaves, in which an increase of 19% over the control was detected. Similarly, a 50% increase in the number of flower was recorded. It is of great importance to stress again that low concentrations of salicylic acid have the best effect, as we have reported in recent years.
