## 4 Discussion  
The observed data showed concurring results of AGE on the growth and physiology of pepper and eggplants seedlings. Application of ASA also influenced the growth and development of the treated plants with statistical difference. These findings matched our previous results on the bioactivity of AGE in the growth of subject plants [28; 37]. Based on current results, plant growth parameters such as plant height, leaf area, and shoot and root weights, as well as root length, were significantly altered. The growth improvement in the plants can be established by the fact that garlic extracts contain various growth-promoting compounds such as starch and vitamins, and organosulfur compounds such as allicin and diallyl disulfide, etc. [38; 39; 40]. Growth-promoting effects of aqueous garlic extracts have been reported previously in tomato. However, in current findings, there seems to be strong correlation between the morphological indices and the developmental aspects such as chlorophyll or carotenoid contents. These findings are in corroboration with previous results. Application of AGE-Improved Photosynthetic Pigments, Soluble Sugars Accumulation, and Incremented Root Development, Promoting Plant Growth  
Improvements in the growth of pepper and eggplant corroborate our previous reports about the inductive bioactivity of AGE towards receiver plants. Prime morphological characters such as leaf area, plant height fresh weight, etc., were influenced by AGE and ASA treatments. Garlic contains significant products such as vitamins, proteins, and starch, and the increased growth in the treated plants seems to be the outcome of these important ingredients that are present in the garlic extracts [41; 42; 43]. Furthermore, ASA also enhanced the growth parameters of the treated plants. Exogenous application of ASA has been reported to have improved the growth and performance of maize plants under saline conditions [44], supporting our findings. As previously reported, AGE's foliar applications accelerate growth of receiver plants through stimulation of photosynthetic pigments and soluble sugar contents [45]. Our findings on the stimulation of soluble sugar contents and photosynthetic pigments in the eggplant and pepper are therefore in strong agreement with these results. A stimulated photosynthesis system reflects an enhanced food factory [46; 47], which may have influenced the

Interestingly, root length was significantly influenced due to the aqueous garlic extracts application. This increase in root length was further investigated with the root activity in the eggplant and pepper seedlings, and it was observed that the root activity of both plants species was significant compared to those of the control plants. Enhanced root activity has been earlier reported to have been influenced by promoted root growth [34]. Promoted root growth further facilitates the uptake of nutrients from the rhizosphere, thus enabling the plants to accumulate incremented dose of water and soluble nutrients, subsequently improving the plants' growth [48; 49]. We observed incremental responses in the soluble sugars, chlorophyll a, and total chlorophyll content of the treated plants. Chlorophyll being a photosynthetic pigment, is believed to be a source of ensured energy supply [50; 51]. Furthermore, the carotenoid contents of the eggplant and pepper showed significant variation compared to those of control plants. Carotenoids are considered to play a vital role in plant development, particularly under stress conditions [52; 53].
