Abstract
Post-infectional changes in sugars, ascorbic acid, protein, phenols, chlorophyll and carotene of two Cymbopogons viz., Cymbopogon martinii and Cymbopogon citratus due to leaf rust caused by Puccinia nakanishikii (Diet) were investigated. All the biochemical constituents decreased in plants infected by the fungal pathogen.
Highlights
Cymbopogon martinii (Roxb) Wats (Palmarosa) and Cymbopogon citratus (DC) Stapf. (Lemongrass) are essential oil bearing aromatic plants belonging to the genus Cymbopogon
Post-infectional changes in sugars, ascorbic acid, protein, phenols, chlorophyll and carotene of two Cymbopogons viz., Cymbopogon martinii and Cymbopogon citratus due to leaf rust caused by Puccinia nakanishikii (Diet) were investigated
The present investigation was undertaken to study the changes in sugars, ascorbic acid, protein, phenols, chlorophyll, carotene, respiration and transpiration during pathogenesis in Cymbopogon martinii and Cymbopogon citratus
Summary
Cymbopogon martinii (Roxb) Wats (Palmarosa) and Cymbopogon citratus (DC) Stapf. (Lemongrass) are essential oil bearing aromatic plants belonging to the genus Cymbopogon. The oil Cymbopogon martini is used as the base for fine perfumery and is valued because of its geraniol contents. Cymbopogon citratus is one of the sources of citral, an important monoterpene aldehyde, large quantity of which are being utilized for production of ionones, vitamin A and geraniol besides the use in perfumery soaps and cosmetics. C. citratus and C. martinii are two economically important essential oil yielding grasses, due to the infection by rust fungus, these two species of Cymbopogons show serious losses in terms of herb yield, oil content and its quality. Boruah and Bordoli [1] reported the pathogen associated with rust disease of Cymbopogons as Puccinia nakanishikii (Diet). The present investigation was undertaken to study the changes in sugars, ascorbic acid, protein, phenols, chlorophyll, carotene, respiration and transpiration during pathogenesis in Cymbopogon martinii and Cymbopogon citratus
