Karonda seeds are very hard and have low germination per cent but it is propagated through seeds. There are various constraints of low seed germination. Considering this a trial under the title Effect of various pre sowing chemicals on seed germination and vigour in Karonda (Carissa carandas Linn.) was carried out at the nursery of Horticulture Department, Khalsa College, Amritsar, Punjab during 2019-2020. The experiment was laid out in a Randomized Block Design with three replications, consisting of eleven treatments replicated thrice. The results of present investigation revealed that the karonda seeds treated with KNO3 1% Soaking (2hr) (T3) recorded minimum number of days required for germination and maximum germination percentage was observed when karonda seeds soaked in water for 12 hour (T10).The treatment Thiourea2% soaking (2hr) (T9) maintained its superiority in producing maximum, shoot diameter, shoot fresh weight and dry weight whereas length of seedling, dry weight of root, Vigour index-I and vigour index-II reported maximum in T4 KNO3 2% soaking (1hr). However, maximum survival percentage was observed inThiourea2% soaking (2hr) (T9).
