Název v původním jazyce

The consequences of lower nitrogen availability in autumn for internal nitrogen reserves and spring growth of Calamagrostis epigejos

Popis výsledku v původním jazyce

Induced changes in nitrogen availability in the course of two subsequent vegetation seasons were used as a tool for finding i) to what extent high N availability in substrate is important for building N reserves in autumn that support spring regrowth and, ii) if contrasting contents of N storage compounds may result in differences in growth in the next season. Plants in the LN treatment showed significantly lower total N content and also N allocated to mobilizable reserves. External nitrogen availability in autumn is hence highly important for building N reserves in this species. A major portion of the nitrogen stored in HN plants during winter was taken up from growth medium in late autumn, whereas translocation from senescing shoots dominated in LN treatment. Amino acids were identified as the most prominent source of mobilizable N during spring regrowth. Development of leaf area in LN plants was significantly slower in March and April than in HN plants namely due to smaller number o
