| Summary: | Penelitian ini dilakukan untuk mengetahui hubungan konsentrusi eksudat dengan daya hantar air rendaman benih jagging setelah disimpan claim rangka uji mutu benihnya. Rancangan Acak Lengkap digenakan week perlakuan periode penyenpanan 0, I, 2, 3, 4 Wan &dam suhu kamar. Ulangan dilakukan tiga kali. Pengamatan dilakukan terhadap kemsentrasi eksudat anorganik (nitrogen, fosfir, Leine?. kalseum, clan magnesium), data hamar listrik. dava tumbuh benih, serf hobo!' busah clan kering bibit.
Hasil peneleian menunjukkan bahwa dengun semakin lamanya penyimpanan, konsentrasi eksudat anorganik meningkat, daya hamar listrik meningkat, telapi daya tembeh benih don bobot Gibe menurun. Kmisentrusi eksudat mcmiliki ko�elasi posit yang nyata te�hadap daya hantar dan
korelasi negatif yang nyata rerhadop daya tumInth benih dan hobo! bibitnya. Hasil ini memungkinkan peoggwwan daya hamar listrik sebagai indikaior viabilitas benih dan alternatif cora uji daya [umbeh benih jagung.
Kata kunci: elektrolit, eksudat anorganik, daya hamar listrik, viabilitas benih, jagung.
It has been known that deteriorate seeds exudes much ions if soaked in water. This experiment was aimed to assess stored corn seeds viability based on concentration of inorganic exudates and on electrical conductivity (EC) of soaking water of the seeds they generate.
Seeds of zero, one, two, three, and four months in storage were soaked in water. The soaking water then was observed for its nitrogen, phosphorous, potassium, calcium. and magnesium concentration, as well as their respective electrical conductivity. Simultaneously, seeds germination percentage and seedling weight was also observed.
The results indicated that concentration of inorganic exudates and the EC of the soaking water had close and negative relationship with germination percentage and seedling weight along the storage periods examined. Based on this finding, the EC could be used as an alternative method for viability test of corn seeds.
Keywords : electrolite, inorganic exudate, electrical conductivity (EC), seed viability, corn.
