Description
| - Byly analyzovány rozdíly mezi dvěma inbredními a dvěma hybridními liniemi kukuřice (Zea mays L.) v odpovědi na chlad různého trvání (1, 2, 3, nebo 4 týdny) a následný návrat do optimální teploty měřením aktivit fotosystému 1 a 2, obsahu fotosyntetických pigmentů a aktivit antioxidačních enzymů. Aktivita PS 2 a obsah chlorofylu klesl v rostlinách pěstovaných 3 nebo 4 týdny v chladu, ale ne při kratším období (1 nebo 2 týdny). Tento pokles byl výraznější u inbredních linií. Aktivita superoxiddismutasy nezávisela na době trvání stresu (1.2,3,4 týdny) u inbrednich, ale poklesala u hybridních linií. Aktivita glutathionreduktasy vzrůstala u obou druhů genotypů, ale do větší míry v inbredních liniích. Naproti tomu změny askorbátperoxidasy a katalasy nevykazovaly specifickou tendenci ke vztahu rodiče-hybridi. Aktivita fotosystému 1 a obsah karotenoidů nebyly téměř ovlivněny. (cs)
- The differences between two maize (Zea mays L.) inbred lines and their F1 hybrids in their response to chilling periods of various duration (1, 2, 3 or 4 weeks) and subsequent return to optimum temperatures were analysed by the measurement of the photosystem (PS) 1 and 2 activity, the photosynthetic pigments’ content and the activity of antioxidant enzymes. The PS2 activity and the chlorophyll content decreased in plants subjected to 3 or 4 weeks of chilling, but not in those subjected to 1 or 2 weeks of chilling. This decrease was more pronounced in inbreds compared to their hybrids. The activity of superoxide dismutase did not much change with the increasing length of chilling period in the inbreds but decreased in the hybrids, the glutathione reductase activity increased in both types of genotypes but more in the inbred lines, while for ascorbate peroxidase and catalase the changes in parentshybrids relationship did not show any specific trend. The PS1 activity and the carotenoids’ content was...
