rescences were measured. The latter ones were recorded only from 1998. The fruits were counted three weeks after the flowering time. The inflorescences which were not able to develop in consequence of the drought were not taken into consideration, because they could not be found only by chance. The damaged inflorescences and spikes without any flowers bitten off by caterpillar were also neglected.

The data of reproductive characteristics (height of flowering plant, number of flowers and fruits) were evaluated in the whole investigation period (17 years), but the lengths of inflorescences were measured over 11 years. The Q-Q plot and if this method gave ambiguous results Kolmogorov-Smimov test were applied to test the normality of data. The majority of the reproductive characteristics studied (except the fruit number) show normal distribution. Duncan test was used for comparing reproductive traits to detect inter-annual fluctuations. In the case of the fruit number due to the lack of normality non-parametric tests (Mann-Whitney and Kruskal-Wallis H test) were used for the same purpose. Linear correlation was calculated to detect the relationship between reproductive characteristics. All statistical analysis were carried out using the software package SPSS 13.1.

Results

The number of flowering individuals varied considerably between years (between 10 and 73 individuals) (Fig. 2). Richest years in inflorescences were 1995, 1996 and 2005, while the poorest were 1993 and 1994 and the beginning of 2000’s (2000, 2001,2003), respectively.

The average height of flowering plants was 51.0 cm, while the lowest value was 18 cm, the highest was 97 cm (Fig. 3). There was a significant relationship between the number of flowering individuals and the average height of flowering individuals (r=

0.654, p<0.05, df=16).
