THE EFFECT OF INDOL-3-ACETIT ACID ON PRODUCTIVE CHARACTERISTICS OF BULBOUS CORM FLOWER SPECIES

Abstract

In order to obtain the best quality of flowers, contemporary flower production is increasingly relying on the use of phytohormones and biostimulators. Thanks to the widespread application, in recent years, their use in production of bulbous corm flower species has been increasingly examined, especially phytohormones. The justification of the use of indole-3- acetic acid in the production of bulbous corm flower species is reflected in the possibility of improving productive characteristics. In this paper was examined the effect of the application of indole-3-acetic acid as a microbiological fertilizer - commercial name Slavol - on the productive characteristics of two species of the genus Gladiolus sp. and Lilium sp. During the research, the bulbs and corm was soaking in two different time intervals (1 h and 24 h) and in two different concentrations of Slavol (100 ml and 150 ml). The obtained results showed the positive effect of the application of indole-3-acetic acid on the examine productive characteristics: plant height, overhead mass, number of leaves, number of flower buds, length of the flower and weight of bulbs. Studies have also shown that for species of the genus Lilum sp., a greater impact on productive characteristics has the concentration of indol-3-acetic acid in relation to the duration of treatment, while for species of the genus Galdiolus sp. a greater impact has shown the duration of the treatment.
