“…However, germination tests can be time-con- In this study, the excised embryos of the two Acer species readily grew mold under the highly humid incubation conditions when they were only sterilized according the ISTA protocol (ISTA, 2013). This sterilization method was shown to be suitable for other species, including Sapium sebiferum (Li et al, 2012a) and Fraxinus chinensis (Li et al, 2012b). However, the recommended method yielded seed viabilities significantly lower than seed germination percentage for both A. pictum and A. rubrum, indicating it was inadequate to evaluate seed quality of these two maples.…”

Sapium sebiferum, an ornamental and bioenergetic plant, is propagated by seed. Its seed coat contains germination inhibitors and takes a long time to stratify for germination. In this study, we discovered that the S. sebiferum seed coat (especially the tegmen) and endospermic cap contained high levels of proanthocyanidins. Seed-coat and endospermic cap removal induced seed germination whereas exogenous application with seed-coat extract or proanthocyanidins significantly inhibited this process, suggesting that proanthocyanidins in the seed coat played a major role in regulating seed germination in S. sebiferum. We further investigated how seed-coat extract affected the expression of the seed-germination-related genes. The results showed that treatment with seed-coat extract upregulated the transcription level of the dormancy-related gene, gibberellins suppressing genes, abscisic acid biosynthesis and signalling genes. Seed-coat extract decreased the transcript levels of abscisic acid catabolic genes, gibberellins biosynthesis genes, reactive oxygen species genes and nitrates-signalling genes. Exogenous application of nordihydroguaiaretic acid, gibberellic acid, hydrogen peroxide and potassium nitrate recovered seed germination in seed-coat-extract supplemented medium. In this study, we highlighted the role of proanthocyanidins, and their interactions with the other germination regulators, in the regulation of seed dormancy in S. sebiferum.

“…We investigated the water uptake of intact seed and sulfuric acid scarified seed by (Li et al 2012) method. Our results showed that water uptake gradually increased from untreated (control) 0 to 10 minutes, 20-, 30-, 40-, 50-, and 60 minutes.…”

Sapium sebiferum, a highly ornamental and bioenergy plant, is propagated by seed. Its seed coat contains germination inhibitors and needs long time stratification for germination. In this experiment, we discovered that S. Sebiferum seed coat (especially tegmen) and endospermic cap contained high levels of proanthocyanidins (PAs). Seed coat and endospermic cap removal induced seed germination whereas exogenous application with seed coat extract (SCE) or PAs significantly inhibited this process, suggesting that PAs in the seed coat played a major role in regulating seed germination in S. sebiferum. We further investigated how seed coat extract affected the expression of the seed germination-related genes. The results showed that SCE treatment upregulated the transcription level of the dormancy-related gene, abscisic acid (ABA) biosynthesis and signalling genes and gibberellins (GA) suppressing genes. SCE decreased the transcript levels of ABA catabolic, GA biosynthesis, reactive oxygen species (ROS) and nitrates signalling genes. Exogenous application of nordihydroguaiaretic acid (NDGA), gibberellic acid (GA 3), hydrogen peroxide (H 2 O 2) and potassium nitrate (KNO 3) recovered seed germination in SCE supplemented medium. In this experiment, we highlighted the role of PAs, and its interactions with the other germination regulators, in the regulation of seed dormancy in S. Sebiferum.
