Biochemical Test of Rice Seeds (Oryza sativa L.) that have been Invigored

Abstract

Storage of seeds will affect the age of the seeds, so the storage of seeds must be done properly and correctly. During storage, the seeds will experience deterioration. Deterioration can not be avoided but can be slowed as long as the condition of storing the seeds is well maintained. Deterioration the quality of rice seed greatly affect the growth and yield of rice in the field, to the need to find a solution with the method invigorasi such as the treatment of priming and hydration-dehydration. The purpose from Research of this is to know the biochemistry of seeds already in invigoration. This research has been carried out at LLDIKTI Laboratory Region X West Sumatra, Riau, Jambi and Riau Islands from September to October 2019. Experiment is this use Design Randomized Complete (RAL) with a two-factor factorial pattern. The first factor are varieties of rice (Batang Piaman, PB42, and IPB3S) and the second factor are methods invigorasi ( priming and hydration-dehydration). Variables measured either be a the seed moisture content, seed germination, soil emergent test, the content of ash, fat content, and respiration rate. The observational data were analyzed with F test of 5% significance level. If it is significantly different, it is continued with further testing of BNJ at the 5% level. The results showed that invigoration could be increase seed moisture content, seed germination, and soil emergent test. Treatment of seeds with invigoration can activate the biochemical processes in the seed, there are by increasing fat content, and respiration rate but decreasing ash content.
