Contents of polyamines during vernalization in wheat and the effect of zearalenone

Original language description

The contents of endogenous free and conjugated polyamines, putrescine (Put) and spermidine (Spd), were determined during vernalization in winter wheat seedlings cultivated without (MS0) and with 2 mg dm-3 zearalenone (MSZEN). At the 4th week of chillingtreatment the marked increase in free and conjugated forms of Put and free Spd were observed. About 20 % of plants treated with ZEN flowered already after 2 weeks and 40 % after 3 weeks of chilling. Significantly higher content of free Put was determinedin roots grown on MSZEN compared with MS0 during the first 5 weeks of vernalization with maximum at the 4th week. After germination, a marked decrease in free Spd content was observed both in plants grown on MS0 and MSZEN. Application of ZEN slowed downthe Spd decline in leaves and roots during the first and second week of vernalization. The content of Spd and its conjugates decreased in vernalized plants after 1 week of cultivation at 20°C.
