The studies on seed viability, germination and seedling growth of karonda seeds were carried out at the nursery of department of Horticulture, Khalsa College Amritsar during the year of 2018-2019. In the trial seeds of karonda were collected and sown according to the seven treatments viz., zero days of extraction, 12 days of extraction, 24 days of extraction, 36 days of extraction, 48 days of extraction, 60 days of extraction and 72 days of extraction with three replications. The investigation was laid out in Randomized Block Design. The results of the study revealed that the seed germination was significantly the highest (63.32%), when fresh seeds were sown. The seedling height , number of leaves, fresh and dry weight of shoots, root number and vigour index varied with the storage period of seeds. The seeds sown at zero days of extraction gave 50 percent germination in 10.33 days and completion of germination in 20.34 days. After 12 days of extraction it took 13.33 days and 26.00 days for 50 percent germination and completion of germination respectively. The seeds sown after 12 days of extraction (12 days stored seeds) upheld good germination and seedling vigour therefore, karonda seeds could be stored for 12 days after extraction from fruits at ambient condition with good seed viability and vigour.
