Agronomic Performance of Sweet Corn Yield and Quality Due to Colchicine Application

This study aimed to determine the agronomic performance of sweet corn plants due to the administration of colchicine to seeds that had germinated and were soaked in colchicine with different soaking durations. The study used a Randomized Group Design with treatments consisting of sprouts not soaked in colchicine (control), soaked for 5, 10, 15, 20, and 25 hours. Each treatment was repeated 3 times with a total observation sample of 5 plants/plots. The variables evaluated included the number of cobs/plant, cob length, cob diameter, cob fresh weight with clobber, cob fresh weight without clobber, number of seeds/row, number of seeds/circle, seed hardness, total soluble solids, stomatal length, width, and area, and stomatal density. The results showed that soaking the sprouts in 600 ppm colchicine for 20 hours gave larger sweet corn cobs and larger stomata. The longer soaking resulted in the highest seed hardness but low total soluble solids.
