Seed germination of some flower species under influence of different light conditions
Investigation was conducted in the laboratory for vegetables, floriculture, medical and aromatic herbs on Faculty of Agriculture in Osijek during the year 2015. Seeds of Zinnia elegans Jacq., Dianthus caryophyllus L. and Callistephus chinensis (L.) Nees that were used in the research were purchased in local store. In preparation for germination, petri dishes were sterilized with 96 % ethanol and seeds of every flower species were counted. Experiment was set up in three replicates for each light treatment and each flower species. Counted seeds were placed in petri dish on filter paper that was moistened with 5 mL of distilled water. Prepared petri dishes with seeds were then placed in growth chamber under artificial white and blue light under 12hL/12hD photoperiod. Temperature during the research was constant (23 ± 1 °C). During the first week, number of germinated seeds was recorded daily, and on the seventh and the fourteenth day germination energy and total germination were determined respectively. Seedlings length and mass were recorded at the end of experiment. Results of the research showed no significant difference in germination energy and total germination of all investigated flower species in respect of light. Zinnia seedlings were significantly longer on white light, while Dianthus seedlings were longer on blue light. Both, length and mass of Callistephus seedlings were greater on white light. The research suggests that, in the initial stage of germination, Zinnia, Dianthus and Callistephus are not photosensitive and therefore no significant differences in the estimated parameters occurred. The assumption is that, in further stages of development, these differences certainly would have occurred so we can conclude that this research should be continued throughout the growth and all development stages of investigated flower species.
