Abstract

Tanaman padi (Oryza sativa L.) merupakan salah satu tanaman pangan utama yang memiliki peran penting dalam memenuhi kebutuhan pangan masyarakat. Namun produktivitas padi dapat menurun akibat cekaman salinitas yang menghambat proses perkecambahan dan pertumbuhan awal tanaman. Salah satu upaya untuk mengurangi dampak negatif salinitas adalah melalui pemberian nanopartikel silikon (SiNPS). Penelitian ini bertujuan untuk menganalisis pengaruh cekaman salinitas terhadap daya perkecambahan dan pertumbuhan awal tanaman padi, serta pengaruh pemberian SiNPS pada kondisi cekaman
salinitas. Penelitian ini menggunakan 17 varietas padi, antara lain IR64, Jeliteng, Mantap, Pamerah, Situ Bagendit, Pamelen, Situ Patenggang, IR29, Inpari 35, Bahbutong, Badui C, Badui D, Jambi 2, PM 1, PM 2, PM 4, dan PM 5. Perlakuan yang diberikan terdiri atas kontrol (aquades), NaCl 100 mM, NaCl 200 mM, NaCl 100 mM + SiNPS 50 µM, dan NaCl 200 mM + SiNPS 50 µM. Proses perkecambahan dilakukan pada media cawan petri yang dilapisi kertas saring selama 9 hari dengan tiga kali pengulangan. Parameter yang diamati meliputi daya perkecambahan, panjang akar dan berat tanaman yang diamati setiap tiga hari. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi NaCl cenderung menurunkan daya perkecambahan dan menghambat pertumbuhan awal tanaman padi. Sebaliknya, pemberian SiNPS pada kondisi salinitas terbukti mampu meningkatkan daya perkecambahan serta memperbaiki pertumbuhan awal tanaman dibandingkan perlakuan salinitas tanpa SiNPS. Selain itu, setiap varietas menunjukkan respons yang berbeda terhadap cekaman salinitas maupun pemberian SiNPS yang mengindikasikan adanya variasi tingkat toleransi antar varietas. Dengan demikian, pemberian SiNPS berpotensi membantu mengurangi dampak buruk cekaman salinitas pada fase perkecambahan dan pertumbuhan awal tanaman padi.

Rice (Oryza sativa L.) is a major food crop that plays a vital role in meeting public dietary needs. However, rice productivity can decline due to salinity stress, which inhibits seed germination and early plant growth. One effort to mitigate the negative impacts of salinity is through the application of silicon nanoparticles (SiNPs). This study aimed to analyze the effects of salinity stress on the germination and early growth of rice, as well as the impact of SiNPs application under saline conditions. The experiment utilized 17 rice varieties, including IR64, Jeliteng, Mantap, Pamerah, Situ Bagendit, Pamelen, Situ Patenggang, IR29, Inpari 35, Bahbutong, Badui C, Badui D, Jambi 2, PM 1, PM 2, PM 4, and PM 5. The treatments consisted of a control (distilled water), NaCl 100 mM, NaCl 200 mM, NaCl 100 mM + SiNPs 50 μM, and NaCl 200 mM + SiNPs 50 μM. Germination was conducted in petri dishes lined with filter paper for 9 days with three replications. Observed parameters included germination percentage, root length, and plant weight, which were recorded every three days. The results showed that increasing NaCl concentrations tended to decrease germination percentage and suppress the early growth of rice plants. Conversely, the application of SiNPs under saline conditions was proven to enhance germination and improve early growth compared to salinity treatments without SiNPs. Additionally, each variety displayed a distinct response to both salinity stress and SiNPs application, indicating variations in tolerance levels among the varieties. Therefore, SiNPs application has the potential to help reduce the adverse effects of salinity stress during the germination and early growth stages of rice.
