KADAR AIR DAN KARBOHIDRAT BERPERAN PENTING DALAM MEMPERTAHANKAN KUALITAS BENIH KARET
ABSTRACT: Determination of the
main variables of seed quality is very important that the control variables can
be done to the fullest. This issue has been addressed through a trial that aims
to determine the main variables that affect the quality of the rubber seeds in
storage. Experiment was conducted from April to August 2012 at the Basic
Laboratory, The Batanghari University, Jambi and Center for Post Harvest
Research and Development, The Ministry of Agriculture, Bogor. The experimental
design used was completely randomized design. The treatment were storage time
as follows: S0 = control, 0 days of storage, S1 = 3 days of storage, S2 = 6
days of storage, S3 = 9 days of storage, and S4 = 12 days of storage, S5 = 15
days of storage, and S6 = 18 days of storage. Each treatment was repeated three
times so that there are 21 experimental plots. In this study, experimental
plots considered a seed lot. Each lot contained 60 of rubber seed. The results
showed that 80% germination can only be maintained until day 9 with indicators
respiration rate of 3.68 ml CO2 hr-1, water content of 40.25%, protein 23.45%,
carbohydrate 23.15%, fat 24.76 %, and electric conductivity 80 µS cm-1 g-1. The
main variables that maintain seed quality in storage is the water content and carbohydrate.
Efforts to maintain the water content remains high should be done at a temperature
of about 20oC due to low temperature will reduce the rate of respiration.
