Abstract
To explore how manganese affects the antioxidant system and the expression levels of related genes of “Hong yang” seedlings, the leaves of its tissue cultured seedlings were taken as test materials, and single factor treatment was performed by changing the manganese chloride (MnCl2.4H2O) solution concentration when spraying the leaves. The expression levels of Mn-SOD, POD64 and POD27 genes in leaves were quantitatively analyzed by real-time quantitative PCR (qRT-PCR) at different determination times. Meanwhile, the contents of malondialdehyde (MDA), hydrogen peroxide (H2O2), the activities of antioxidant enzymes, including catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD). The results showed… More >
