Změny obsahu kyseliny abscisové a produkce etylénu v průběhu tvorby hlíz brambor (Solanum tuberosum) in vitro

Original language description

The objective of this study was to determine the relationships between the level of abscisic acid, ethylen and CO2 production and potato microtuber formation in vitro. Stem nodal segments of potato plants were cultivated in vitro 8 weeks on Murashige-Skoog medium containing modified level of inorganic nitrogen (10-12 microM or 65 -70 microM), 80 g/1 sucrose and 10 mg/l benzylaminopurine. Cultures with low nitrogen level in induction medium showed higher frequency of tuber formation. During induction oftuber formation (first two weeks of cultivation) nodal segments produced ethylene. Later ethylene production inhibited the growth of stolons and tuber formation. Higher level of abscisic acid was determined in leaves, later in stolons and tubers on nodalsegments cultivated on induction medium with low level of nitrogen.
