The effect of mechanically-induced stress on Calendula officinalis, Tagetes patula and Tagetes erecta transplants
The aim of this work was to investigate the effect of mechanically-induced stress on morphological characteristics and flowering time of Calendula officinalis L., Tagetes patula L. and T. erecta L. transplants. The plants were subjected to daily brushing treatment with a cotton cloth. At the time of anthesis, the plant height was not statistically significantly different between treated and untreated group, in none of the investigated species. In T. patula, the treatment also did not influence other measured morphological parameters. However, in T. erecta, treated transplants had slightly higher stem diameter and also higher numbers of lateral branches and leaves than untreated ones, while in C. officinalis, the treatment resulted in more erect stems. Besides, treated plants in both species had a higher number of inflorescence buds. Although the treatment slightly shifted the date of flowering onset in T. erecta, the number of days to 50 % flowering was not affected by brushing in the investigated species. The results of this study show that mechanically-induced stress may improve some of the commercially important characteristics of C. officinalis and T. erecta. However, brushing also caused damage on some leaves, especially in C. officinalis. For these species, further research is needed to find out the effectiveness of other methods of applying mechanical stress, in particular those in which physical contact with plants is reduced or avoided.
