Abstract

The aim of the study was to investigate how salinity stress, specifically the addition of NaCl, affects the growth of purple corn plants. The study was conducted between August and November 2020 at the Seed Science Laboratory and Screen house, Faculty of Agriculture, Tadulako University, Palu, and employed a completely randomized design (CRD) with four treatments. The treatments included a control group with no NaCl added (N1), and three experimental groups with increasing levels of NaCl concentration: 1,500 ppm (N2), 3,500 ppm (N3), and 4,500 ppm (N4). Each treatment was replicated five times, making up a total of 20 experimental units. The results of the study indicated that the addition of NaCl had a significant effect on the total dried weight of the purple corn plants. Salinity stress caused poor growth or inhibition of the vegetative organs of the purple corn plants. The study found that the tolerant limit for purple corn to grow in terms of NaCl concentration was 3,500 ppm. Overall, this study provides insights into how salinity stress, specifically through the addition of NaCl, can impact the growth of purple corn plants. The findings suggest that excessive salinity levels can significantly affect plant growth, and that there is a threshold limit for NaCl concentration beyond which the plants become less tolerant.

Abstract

Pengaruh Konsentrasi Asam Sulfat dan Metode Skarifikasi Terhadap Perkecambahan Benih Aren (Arenga pinnata Merr.). Penelitian ini dilaksanakan di Laboratorium Teknologi Benih Fakultas Pertanian Universitas Tadulako, palu, yang dimulai dari bulan Februari hingga April 2020. Tujuan penelitian untuk mengetahui interaksi antara berbagai konsentrasi asam sulfat dan metode skarifikasi. Penelitian ini Menggunakan Rancangan acak kelompok yang terdiri dari dua faktor. Faktor pertama adalah konsentras asam sulfat dengan empat taraf yaitu 0%, 25%, 50%, 75% dan faktor kedua metode skarifikasi dengan tiga macam yaitu pengamplasan, pengikiran dan peretakan. Terdapat 12 kombinasi percobaan setiap kombinasi percobaan diulang 3 kali sehingga diperoleh 36 unit percobaan. Paramater pengamatan daya perkecambahan (%), kecepatan perkecamabahan (%/etmal), panjang radikula (cm), bobot basah dan bobot kering kecambah (g). Hasil penelitian menunjukkan bahwa interaksi antara konsentrasi asam sulfat dan metode skarifikasi berpengaruh nyata terhadap pengamatan daya perkecambahan dan kecepatan perkecambahan kecuali pada pengamatan panjang radikula, bobot basah dan bobot kering kecambah. Kombinasi perlakuan konsentrasi 50% asam sulfat dan skarifikasi peretakan dan pengamplasan memberikan data tertinggi pada pengamatan daya berkecambah dan kecepatan berkecambah, yaitu (8,25 % dan 5,75%), (2,28 dan 2,12%/etmal).
