Sažetak
Traditional flower species used to be one of the most important parts of traditional rural gardens, along with vegetables and aromatic and medicinal herbs. During the 20th century, as the way of life in rural populations began to change, traditional rural gardens and traditional flower species started to die out. Today, amateur gardeners are trying to renew traditional rural gardens, what often results in gardens filled with flower species commonly found in large chain stores, retail stores and markets. Poor seed quality might be the cause of disappearance of traditional flower species. Flower seed isn't produced in Croatia, so the seed supply is based only on the import of seed, whose quality parameters aren't legally determined. 18 samples of ten flower species imported 2011/2012: Ageratum hosutonianum, Calistephu schinensis, Cosmos bipinatus, Dahlia pinata, Impatiens walleriana, Lavandula officinalis, Lobelia erenis, Tagetes patula, Verbrena × hybrida, Zinia elegans have been tested on their seed vigour, germination and seed health by the ISTA international testing methods. Besides the traditional flower species, a few commercial flower species have also been included in the tested sample. Emergence rate in containers, growth in flower pots and inflorescence colour have been tested on eight flower species: Ageratum hosutonianum, Dahlia – mini, Impatiens wallerina, Lavandula officinalis, Lobelia erinus, Tagetes patula, Verbena × hybrida and Zinnia elegans. Germination of the majority of tested flower species was under 50%, and in the commercial flower species it was somewhat higher. The most common seed diseases are: Alternaria alternata, Fusarium spp. and Verticillium sp., and on some samples the infections with these diseases were over 40%. Emergence rate in containers is poor on samples with low seed vigour. Inflorescence colours of the flowers are different than the ones on the seed packages. Bad seed quality, poor emergence rate in containers, and incompatibility of inflorescence colour and plant height with the certified ones are the main causes for the disappearance of the traditional flower species. Amateur gardeners mostly buy their seeds in retail, but due to poor quality they give up on planting and cultivating traditional flower species. With the disappearance of traditional flower species, traditional rural gardens are also dying out.
