MARTIN-MEX, Rodolfo et al. Salicylic acid stimulates flowering in micropopagated gloxinia plants. Rev. fitotec. mex [online]. 2015, vol.38, n.2, pp.115-118. ISSN 0187-7380.

Micropropagated gloxinia (Sinningia speciosa Benth.) seedlings transferred to greenhouse conditions, were treated with salicylic acid (SA) to test its effect on flowering. Concentrations of 1.0 to 0.0001 μM of SA were sprayed on the shoots on three occasions. Results showed that all SA concentrations tested increased the total number of flowers per plant by 25 to 37 %. Flower length increased 11 % by SA at 1.0 μM. All SA treated plants flowered 6 d earlier and had higher leaf area compared to control plants.

Palabras llave : Sinningia speciosa; salicylic acid; flowering; plant growth regulator.
