###### Abstract
Previously, the use of Salicylic Acid (SA) has been reported to enhance seed germination and seedling vigor in eggplants by altering various physiological functions [18]. SA is a hormone signaling molecule suggested to induce defense responses of the plants upon pathogen attack [16]. Moreover, methyl jasmonate (MeJA), which is an endogenous plant growth regulator, regulates plants defense responses and alleviates the stress situations on the plants [19]. Exogenously applied MeJA can enhance primary defense responses of the subject plants and may affect plant growth depending on the concentration applied as reported by [PERSON] et al. (2017a,b). MeJA with increased concentrations could inhibit the germination and plant growth of rice as compared to low concentrations [20; 21]. Recent advancements into the use of agricultural bio-stimulants have gradually paved the way for the horticultural community to explore various botanical bio-stimulants to enhance growth, development, and/or the defense system of the subject plants [22]. As the name suggests, a bio-stimulant could be a single biochemical or a formulation of numerous compounds extracted or obtained from organic origin that bear the potential to bring about considerable changes in the physiology of the receiver plant. Based on their activity, they can be further categorized as promotors, inducers, or stimulators [23; 24; 25]. Plant derived secondary metabolites have been proposed by various researchers to induce the defense responses or improve the growth and development of the subject plants [26; 27]. Furthermore, plant allelopathy has also been suggested to induce signals in the receiving plants which alter their physiological and molecular responses and, therefore, influence their growth and development [28; 29]. Garlic among the plant species is been regarded as an allelopathic plant, which influences soil microclimate, enhances biological activities therein, and results in improved plant growth and metabolism. Previously, intercropping with garlic has been suggested to alleviate continuous cropping obstacles [30; 31]. Intercropping with garlic has also been proposed to improve cucumber growth and soil properties [32; 33]. However, intercropping different plant species creates competition for nutrients and space and may affect the producibility. Apart from intercropping, numerous studies reported the direct influence of garlic extracts and garlic derived allelochemicals on the growth and physiology of various vegetables [34; 35; 36; 37; 38]. The presence of organosulfur compounds such as allicin and Diallyl disulfide (DADS) or Diallyl trisulfide (DATS) allows speculation on the bioactivity of garlic extracts in the physiology of receiving plants [34; 35; 39]. The concentrations of garlic biochemicals may influence the resulting growth of the plants [36], additionally, the method of application also affect the bioactivity of these biochemicals [40; 41; 42]. Nevertheless, these studies mostly involve the application of garlic compounds either as a foliar spray or root fertigation upon the seedlings. The question therefore exists that whether or not garlic allelochemicals bear the potential as a seed-priming bio-stimulant to enhance seed germination, which not only may improve the resulting plant growth but also, if possible, alleviate the environmental stresses ensuring the utility of space, water and nutrients by the treated plants. The present study demonstrates garlic extracts as plant bio-stimulant to induce priming effects on the biological activities of the eggplant seeds during seed germination and early seedling development. Our study encompasses germination potential and indices, morphological observations (size, weight), and biochemical processes particularly the soluble protein abundance, lipid peroxidation levels (MDA content), antioxidant enzymes activity, and reactive oxygen species modulation, which are often regarded important during early growth establishment in plants.
