Bashkirova, K.A. | Bobkov, S.V.
Study of photosynthetic pigments content and activity of antioxidant system in stipules of asiaticum accession pea k-1974 and variety Salamanka (ssp. sativum) at the beginning of seed filling were conducted. There were no statistically significant differences between accession k- 1974 and variety Salamanka on content of pigments and the activity of antioxidant enzymes were not revealed. In the stipules of accession k-1974 ratio of chlorophylls to carotenoids was 0,77 units significantly higher (p≤0,001) than in ones of cultivated pea. In variety Salamanka, ratio of chlorophyll a to chlorophyll b was 0,22 units significantly higher (p≤0,05) than in the accession k- 1974. In stipules of accession k-1974 there was strong positive relationship between activity of catalase and content of chlorophylls and carotenoids at the beginning of seed filling. In Salamanka there was significant strong and moderate positive correlation between content of photosynthetic pigments and activity of catalase, and consequently, activity of peroxidase.
