Seed priming in Tomato

This is a reference book to furnish students and teachers the more valuable information in a precise & consolidated manner at one place, covering tools and techniques, & also describes the importance of Tomato, problems of salinity,abiotic stress & strategies to cope up such environmental stresses through priming techniques. Tomato (Lycopersicon esculentum Mill.) is one of the important remunerative vegetables in our country and in the world. Among environmental stress, salinity is one of the key factors which can limit the distribution and productivity of plants worldwide.Seed priming has been successfully demonstrated to improve germination and emergence in seeds of many crops, particularly seeds of vegetables and small seeded grasses.Polyethylene glycol (PEG) is one of the most prevalent treatment. This treatment does not have any physiological responses to seed and in order to having more molecular weight cannot pass the cell wall and so it be used for water potential adjustment in germination experiments.
