Effect of Seed Treatment on Hydration-Dehydration Respiration Sprouts Sorghum

Abstract

The limiting factor affecting sorghum production in Indonesia is the rapid decline of sorghum seeds, it is necessary to do invigorate one way to hydration-dehydration. The purpose of this study was to know that invigorates with the hydration-dehydration method can increase the respiration rate of sprouts sorghum. This experiment using a completely randomized design (CRD) with 3 treatments and 4 replicates in order to obtain 12 units of trials conducted at the Laboratory of Seed Science and Technology, the University of Andalas from January to March 2019, The treatment in this trial are: A = low-quality seeds, B = Hydration for 1 hour and dehydration for 6 hours at a temperature of 400C, C = high -quality seeds. The data were analyzed by the F test significance level of 5%. If they are real continued by Honestly Significant Difference (HSD) at 5% level. The results showed that hydration-dehydration can increase the respiration rate of sorghum seedlings which have been in decline, from respiration rate 67,434mgCO2 be 82,412mgCO2.
