Abstract

Tomato is widely cultivated and important nutritious vegetable in the world. It deteriorates rapidly after harvesting. High reactive oxygen species (ROS) level has negative effect on growth and development through oxidative stress by affecting physiological and molecular processes. Oxidative stress can be recovered by the scavenging system which consists of enzymatic as well as nonenzymatic antioxidants. So, ROS balance and antioxidant are necessary for better growth and prolong shelf life. As an antioxidant ascorbic acid was applied several times which played key role for plant growth and stress management. This study evaluated the role of ascorbic acid on physical and physiological changes of tomato. A marked variation was observed on some parameters regarding leaf length, panicle length, flower cluster and fruits per plant, chlorophyll content, MDA content, fruit yield per plant etc. Application of ascorbic acid increased leaf length, chlorophyll content, dry matter and decreased MDA content. Flower cluster per plant as well as panicle length was maximum at 45 DAT. Number of fruits and fruit yield/plant was fluctuated slightly with the application of ascorbic acid. Thus antioxidant has played a pivotal role on growth and development of plant.
