Factors Affecting Seed Dormancy and Germination of Greater Bur-Parsley (Turgenia latifolia)

Abstract

Our knowledge about seed dormancy breaking and environmental factors affecting seed germination of greater bur-parsley (Turgenia latifolia) is restricted. This study has addressed some seed dormancy breaking techniques, including different concentrations of gibberellic acid (GA3) and potassium nitrate (KNO3), leaching duration, physical scarification as well as some environmental factors effective on seed germination such as salt and drought stresses, pH and seed planting depth. Seed germination was promoted with lower concentrations of KNO3 (0.01 to 0.02 g L-1), while higher concentrations reduced germination percentage. Seed dormancy was declined by low concentrations of GA3 up to 100 ppm. Seeds of greater bur-parsley germinated in a range of pH from 3 to 7. With enhancement of drought and salt stresses, seed germination decreased. Also, there was no seed germination in a high level of stresses. Seedling emergence reduced as planting depth increased. Use of GA3, KNO3, leaching and physical scarification had a positive effect on seed dormancy breaking of greater bur-parsley. The information from the study increases our knowledge about seed dormancy breaking techniques, response of germination to drought and salt stresses and also determination of distribution regions of greater bur-parsley in the future.

“…Moreover, this difference can be explained by the dormancy state of the seeds. Dormancy is considered as a temporary suspension of growth of any plant structure containing a meristem (Rezvani et al, 2016). These phenomena can help plants to adapt to a variety of habitats and climates and survive in different ecosystems.…”

“…Optimum temperature, moisture content, oxygen, light and nitrate play a decisive role in seed germination (Rezvani et al . 2018). ‘Seed dormancy’ is one of the factors that may affect germination even under environmental favourable conditions.…”
