Abstract

The present investigation to investigate ameliorative effect of salicylic acid (SA) on waterlogged situation was carried out as pot culture experiment in tomato variety H-86 (Kashi Vishesh) in poly house with nine treatments including control in three replications under short term stress. The response of various morphological and biochemical attributes progressively reduced with the increased duration of waterlogged condition. Seeds treated with SA (50 and 100 ppm) or without SA, and foliar application of SA were given alone or in combination. Treated seeds significantly promoted seedling growth and ameliorated waterlogged stress induced responses as confirmed by the changes in growth pattern and several morphological and biochemical attributes. Among treatments, SA (50 ppm seed treatment combined with 100 ppm foliar spray) produced better results in terms of shoot length, leaf number, chlorophyll a, chlorophyll b, sugar and protein content, number of flower, number of fruits and fruit weight per plant as compared to waterlogging control plant.

Reduced growth of tomato and its productivity under waterlogging stress was observed.

SA is an important signaling plant molecule which ameliorated waterlogging stress induced responses in tomato plants
