Water logging remains a significant constraint to crop production across the globe. It affects plant growth, development and cause severe damage to plants from the early stage of growth. Sunflower is an oil seed cash crop favoured all over the world but the crop yield is influenced by water logging. The present study aims to evaluate the tolerance response of a sunflower (Helianthus annuus L.) cultivar NSSH-1084 to water logging stress. Here the effects of five water logging durations (0, 3, 6, 9, 12 days) were assessed during the early vegetative stage. The extent of influence on photosynthetic parameters, biochemical parameters and anti-oxidative enzymes, catalase (CAT) and Guaicol Peroxidase (GPX) were investigated during the water logging period. A decline in chl-a, chl-b and total chlorophyll was perceptible after 3days of treatment. Sequential increase in soluble sugar and protein content was found insignificant for tolerance response above 3 days of treatment. Malondialdehde (MDA) and proline content enhanced for all the durations of water logging. A parallel increase in CAT and GPX activity was observed till 3 days of water logging. The outcome of the investigation indicates remarkable tolerance response of NSSH- 1084 up to duration of 3 days for water logging stress.

Keywords: Water logging stress, NSSH-1084, MDA, proline, CAT, GPX
