Applied Research in Science and TechnologyApplied Research in Science and TechnologyCelery (Apium graveolens) is a horticultural crop with significant economic and culinary value, particularly in Indonesia. Despite growing interest in hydroponic farming, celery cultivation remains limited due to challenges in seed germination, especially under lowland and hot climate conditions. Celery seeds are known for slow and inconsistent germination due to hard seed coats and naturally occurring germination inhibitors like coumarin. Seed soaking in plant growth regulators (PGRs), including natural alternatives such as red onion (Allium cepa L) extract—rich in gibberellins and auxins—has been proposed to enhance germination and seedling vigor. This study aimed to investigate the effects of different soaking durations (24 and 48 hours) and concentrations (0%, 10%, 20%, and 30%) of red onion extract on the germination performance of celery seeds. The results indicate that a 24-hour soaking duration is the most effective in enhancing celery seed germination. However, soaking seeds in red onion extract at concentrations of 10% to 30% resulted in lower germination parameters compared to the 0% concentration. Analysis of the interaction between soaking duration and extract concentration revealed that control seeds achieved germination performance comparable to the best treatment combination, while the highest vigor index and seedling length were observed in seeds treated with 10% red onion extract for 24 hours.
The optimal soaking duration for celery seeds is 24 hours, as opposed to 48 hours.The concentration of red onion extract should ideally be lower than 10%.Interestingly, control seeds (untreated) showed germination performance comparable to the best treatment combination.These findings suggest that a balanced approach to soaking duration and extract concentration is crucial for optimal celery seed germination and early seedling vigor.
Penelitian lebih lanjut perlu dilakukan untuk mengidentifikasi senyawa spesifik dalam ekstrak bawang merah yang bertanggung jawab atas efek positif pada perkecambahan benih seledri, serta mekanisme molekuler yang mendasarinya. Studi ini dapat dilakukan dengan analisis metabolomik dan proteomik untuk mengungkap jalur-jalur biokimia yang terpengaruh oleh ekstrak bawang merah. Selain itu, penelitian perlu mengeksplorasi kombinasi ekstrak bawang merah dengan perlakuan lain, seperti priming osmotik atau perlakuan fisik, untuk menciptakan sinergi yang meningkatkan perkecambahan dan vigor bibit secara signifikan. Terakhir, penting untuk menguji efektivitas ekstrak bawang merah pada varietas seledri yang berbeda dan dalam berbagai kondisi lingkungan, seperti suhu dan kelembaban yang berbeda, untuk memastikan bahwa hasilnya dapat digeneralisasikan dan diterapkan secara luas dalam praktik pertanian.
