Abstract: The laboratory experiment was conducted during 2018-19 having 19 treatments with 4 replications planned with CRD design. Freshly harvested cucumber variety Swarna Sheetal seeds were exposed to various physico-chemical dormancy breaking methods. For physical methods seeds were exposed to a different treatments and duration. For chemical treatments, soaking duration was 24 h. Results revealed that exposure of cucumber seeds to a hot dry air treatment at 70 ℃ for 3 days (T11) showed significantly highest (90.25%) normal seedling per cent, shoot length (14.42 cm), root length (21.07 cm), seedling dry weight (725.00 mg), seedling vigour index-I (3202), seedling vigour index-II (65432) and dehydrogenase enzyme activity (0.051 OD value) compared to other treatments and control and it was found on par with thiourea @ 0.5% (T16). However, significantly highest (0.634 dSm-1) electrical conductivity recorded in control (T1) and lowest (0.227 dSm-1) in hot dry air treatment at 70 ℃ for 3 days (T11). For duration of seed dormancy results showed that cucumber variety “Swarna Sheetal†exists up to 35 to 40 days after harvest with germination per cent of 61.25 to 63.50% respectively.
