|Title of the thesis:||Assessment of achenes germination of chosen weed species for Asteraceae family|
|Summary:||The aim of bachelor work was to find how different locality influence achenes germination of Taraxacum officinale a Tussilago farfara. Collection of achenes of chosen weeds was carried out in different locations. Taraxacum officinale was assessed in locality Lidečko -- orchard, Lačnov -- orchard and Valašská Senice -- orchard. Tussilago farfara was evaluated in locality Lidečko kříž, Lidečko -- garden and Lidečko Račné. The germination of achenes was done in different light conditions. Analyses of variance and method of least square differences (LSD) were used for data assessment. The average of weight of hundert achenes was 0.0731 g by Taraxacum officinale a 0.0462 g by u Tussilago farfara, where the weight differed with locality. The germination of achenes was 74 % by Taraxacum officinale and 40 % by Tussilago farfara. The germination of Tussilago farfara achenes was influenced by achenes maturity. Achenes by both species had higher germination in conditions of day light in comparison with night. This is in correlation with positive fotoblastic reaction of plants. Low germination showed that generative reproduction is important only in localities with favourable conditions for growth and development.|
