Variability of some morphological parameters in crocus plants in relation to growing conditions
Keywords:

The study analyzed the variation of some parameters of the crocus plants in relation to the growing conditions. The experimental variants were generated through three growing substrates and three moments of planting the crocus bulbs, and resulted in nine variants. Plant height (PH) was the studied parameter. Moderate variability was recorded within the V2T2 variant (CV = 23.2726), and low variability was recorded within the other variants. Cluster analysis facilitated the grouping of variants based on similarity (Coph.corr. = 0.834). The experimental variants were positioned differently in relation to the calculated mean value. The V3T1 variant presented negative differences, at the p<0.01 level (oo), the V2T2 variant presented positive differences, at the p<0.01 level (**), the V1T3 variant presented positive differences at the p<0.05 level (*), and the V2T3 variant presented negative differences, at the level of p<0.05 (o). In the case of the other variants, the differences did not show statistical safety. The recorded results showed which growth substrate and planting time led to more vigorous plants, with influence for the ornamental appearance in the current crop cycle, as well as for the next crop cycle.
