An Evaluation of Thiourea Application in Breaking Dormancy of black Nightshade (Solanum Nigrum L)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2019, Vol 9, Issue 3
Abstract
Black nightshade (Solanum nigrum L.) is a medicinal plant which belongs to Solanaceae family and grows widely in the temperate and tropical regions. Seeds of this species possess primary dormancy which restricts germination. The main aim of this study is to break the dormancy present in seeds and to enhance the germination under favourable condition. Hence, various dormancy breaking treatments were imposed on seeds for different durations viz., 6, 12 and 24 hin various solutions viz., water, GA3, Potassium Nitrate, Thiourea,. Dry seeds served as control. The results revealed that seed treatment with thiourea 1% for 6 h recorded the highest germination (85%) than control (23%). The growth of seeds was accompanied with the vigour attributing characters viz., speed of germination (5.9), root length (2.3 cm), shoot length (3.3 cm), vigour index (487).
