Effect of Different Priming Methods on Seed Quality of China Aster

A laboratory experiment was conducted at College of Horticulture, Dr. Y. S. R. Horticulture University, Rajendranagar, Hyderabad during the year 2011-12. The experiment was laid in factorial completely randomised block design comprising two factors viz., age of the seed and then other as priming method. Entire treatments were replicated four times. Seed samples were primed and kept in polyethythelene bag and stored for six months at ambient condition. The treated seeds were used to observe different physiological and biochemical changes in each month upto a period of six months. Storage of the treated seeds up to six months resulted in a gradual decrease in performance of the seed. However, storage of the six months old KNO3 treated seed up to six months was found to be good compared to one year old seed regarding all the quality parametes. Among all KNO3 gave best results
