| Description
| - Zkoumali jsme vliv nutričního stresu způsobeného náhlým snížením minerální výživy na kvetení Arabidopsis thaliana. Použili jsme hydroponický kultivační systém, který nám umožnil přesně kontrolovat hladinu živin. Když byly rostliny kultivovány nkolik týdnů na plném živném médiu a poté přeneseny do zředěného roztoku, byl průkazně zkrácen čas od výsevu do objevení poupat. Toto urychlení kvetení bylo výraznější na krátkém dni než na dlouhém a silnější u ekotypu Ler než u Col a Sf-2. Pokud byly 3 týdny staré rostliny Ler přeneseny do 1000x zředěného živného roztoku při délce dne 8 h, bylo objevení poupat urychleno o 10,8 - 12,8 dne. Tento postup může sloužit jako optimalizovaný protokol pro budoucí studium květní indukce nutričním stresem. (cs)
- The time of flowering is regulated by various environmental cues, and in some plant species, it is known to be affected by abiotic stresses. We investigated the effect of nutrient stress caused by an abrupt reduction of mineral nutrition on flowering of Arabidopsis thaliana. We used a hydroponic culture system that enabled us to precisely control nutrient levels. When plants were grown in full-strength nutrient solution for several weeks and then transferred to a diluted medium, the time from sowing to bud appearance was significantly shortened. This acceleration of flowering was more pronounced in short days than in long days, and stronger in the ecotype Landsberg erecta than in Columbia and San Feliu-2. The response was also affected by the age of plants at the beginning of nutrient stress and by the concentration of the diluted medium: earlier treatment and more diluted solutions strengthened the effect. Flowering was affected by nutrient stress, not by a change in the osmotic potential of the m...
