Peroxidase, polyphenol oxidase and acid phosphatase activities in the stigma-style tissue of Camellia sinensis (L) O. Kuntze following compatible and incompatible pollination

Abstract

Changes in the activities of peroxidase, acid phosphatase and polyphenol oxidase in the stigma-style tissues of three clones of Camellia sinensis (L) O. Kuntze were investigated following legitimate and illegitimate pollina-tion. The activity of polyphenol oxidase and peroxidase increases significantly while that of acid phosphatase and the amount of protein decrease after cross-pollination in all the clones studied when compared to self-pollination. The amount of increase or decrease in the activity of enzymes is clone-specific. The possible role of these en-zymes in self-incompatibility mechanism in tea has been discussed. Keywords: Camellia sinensis, compatible and incompatible pollination,limitation on its performance at high collector current density. Keywords: SiGe DHBT, Si BJT, quasi-saturation, power dissipation, valenceformer averaging 18.02% and the latter 22.26%. Adults of P. hector utilized nearly 24 floral species as nectar sources, whose sugar concentrations (1258%) corresponded with 1550% in psychophilic flowers. They displayed a hovering habit while harvesting nectar, and frequently contacted the essential organs with probosics and head, thus promoting cross-pollination.
