Abstract
The discussion and restrictions over the usage of the chemicals in European crop and ornamental plant production implies the search for novel substitute methods. In the present study, we investigate two alternative strategies to induce compact growth in Kalanchoë. First, we examined the possibility of using ethanol as an alternative plant growth regulator. In parallel, we follow a strategy of generating and investigating transgenic plants. All tested genotypes showed a correlation between the ethanol concentrations and compact growth after ethanol watering. However, high ethanol concentrations (more than 2%) led to leaf damage and delayed flower development in some genotypes. The use of ethanol as a growth regulator for ornamentals has several advantages. Ethanol is a biodegradable molecule that is inexpensive, easy and safe to apply, and non-toxic in the concentrations required. Significant growth retardation was also achieved in transgenic plants of Kalanchoë blossfeldiana with up-regulated Arabidopsis thaliana MKS1 and Nicotiana tabacum GA2ox genes. Both kinds of transgenic lines exhibited approximately 2-fold decrease in the stem length as well as in the length of the internodes. The number of nodes in both cases did not differ from the wild type control or was increased in comparison to the wild type.
