Eficácia da germinação de sementes de tomate em soluções de cenoura, maçã e pepino

Abstract

INTRODUCTION: Plants such as carrots, apples and cucumbers contain allelopathic compounds that can affect the development of other plants, influencing competition for resources and agricultural management. Studies on allelopathy often use tomato seeds as bioindicators due to their sensitivity to these compounds. OBJECTIVE: to investigate the effectiveness of germinating tomato seeds using aqueous solutions obtained from carrots, apples and cucumbers. METHODOLOGY: The study was continuous with aqueous extracts prepared from carrots, apples and cucumbers. The extracts were applied to tomato seeds at a concentration of 100%. Evaluations of germination and initial growth of seedlings were carried out under laboratory conditions. RESULTS: The aqueous carrot extract showed the best results, with a higher percentage of germination (89%) and vigor index (IV= 12.73%) in tomato seeds. Apple and cucumber extracts also positively influenced germination. CONCLUSION: The use of aqueous carrot extract showed promise for stimulating the germination of tomato seeds. However, more research is needed to better understand the mechanisms involved and their application in agriculture.
