Abstract

The storability of seeds is influenced by environmental and genetic factors. This experiment aimed to determine the effect of seed physical and chemical characteristics of various sorghum genotypes on their storability under ± 18 ᴼC temperatures. Seeds from 34 sorghum genotypes harvested at the maturity level 41 days after flowering were treated with an indoor storage temperature of ± 18 ᴼC. Seed germination was periodically observed at post storage of 0, 4, ..., 24 months. The relationship between germination capasity as Y and storage length as X was made by sigmoid or linear regression. Storage capacity (SC) was determined as the storage length (X) when the germination capacity (Y) was 75%. Variables of the physical and chemical characteristics of the seeds of 34 sorghum genotypes were measured. Multiple linear analysis resulted an equation of SC= 63.11 - 2.17L - 2.04P - 0.38C + 1.56T - 18.94P + 1.90SH - 0.51WTG + 0.22SV + 7.26D - 0.04TP with a coefficient of determination, R2 = 0.63 ** and very real (P <0.01), with L = lipid, P = protein, C = carbohydrate, T = tannin, P= Phytin, SH = seed hardness, WTG = weight of one thousand grains, SV = seed volume, D = density, and PT = pericarp thickness. Keywords: lipid, phytin, protein, seed hardness, tannin
