Growing of ornamental flowering plants represents an important sector of horticulture. × (garden pansy) is used in garden beds and borders due to their colorful blooming, which occurs in early spring and late autumn. Nowadays, breeders focus on applying different nutrient solutions to improve the quality, flowering, and ornamental properties of plants, yet electrical conductivity (EC) level is an important fact to know. It is known that higher EC levels can inhibit plants' growth. In the present study, pansy seedlings were subjected to different EC nutrient solutions 1 (control), 2, 3.5, 5, and 6.5 mS cm EC to assess the positive or negative effects regarding the plant's growth and development. The results indicated that an appropriate EC level of nutrient solution can have a positive effect on growth parameters, as well as on the flowering of plants. According to the hierarchical clustering, the used EC nutrient solutions significantly influenced the growth, number of shoots and leaves and the inflorescences number. From the present study results, it can be concluded that even though all EC levels increased growth parameters compared with control, the greatest results were obtained in plants under the effect of the 5 mS cm of EC.
观赏花卉植物的种植是园艺学的一个重要领域。三色堇（× ）因其色彩鲜艳的花朵而被用于花坛和花境边缘，其花期在早春和晚秋。如今，育种者专注于应用不同的营养液来提高植物的品质、开花情况和观赏特性，然而电导率（EC）水平是一个需要了解的重要因素。众所周知，较高的EC水平会抑制植物生长。在本研究中，三色堇幼苗被置于不同电导率的营养液中，分别为1（对照）、2、3.5、5和6.5 mS/cm，以评估其对植物生长和发育的正负影响。结果表明，适宜的营养液EC水平对生长参数以及植物开花均有积极影响。根据层次聚类分析，所使用的不同电导率营养液对生长、茎数、叶数和花序数均有显著影响。从本研究结果可以得出结论，尽管与对照相比，所有电导率水平都提高了生长参数，但在5 mS/cm电导率影响下的植物获得了最佳结果。
