- Opis:
- The objective of this research project were the investigations of apomixis in choosen cultivars and strains of Poa pratensis. The following three Polish cultivars: Alicja, Ani, Nandu as well as three breeding strains: PN/15/R, PN/60/R and PN/162/R were investigated by embryological methods to reveal the reproduction pathway in glasshouse and field conditions. Especially, macrosporogenesis, embryo development and seed formation were analysed. Under over mentioned conditions, also the seeds set after self – and open pollination as well as pollen grain viability were investigated. The obtained data showed that four genotypes i.e. Alicja, Ani, Nandu and PN/60/R seems to be facultative apomicts and two strains (PN/15/R and PN/162/R) have formed seeds only on the apomictic way.
