The present paper deals with the effect of various pretreatments on seed germination behaviour of Grewia villosa, an important medicinal plant of the Indian Thar desert. Data on various parameters such as germination, seedling growth, vigour index, etc. as influenced by different pretreatments like acid and mechanical scarifications, nitrate salt solutions, etc. were recorded. The results revealed that maximum values for germination percentage and germination value (GV) in fresh and one-year-old decoated seeds were recorded when pretreated with mechanical scarification (MS). The highest values for vigour index (VI) in fresh (536.64) and oneyear-old seeds (584.08) were also reported in this pretreatment.
