Species of Avena differ markedly in their levels of pre- and post-harvest dormancy. These species offer the opportunity of determining if dormancy is related to the endogenous level of growth inhibitor. Germinability in two species of differing levels of dormancy, common oat Avena sativa L., and wild oat Avena fatua L. was assessed as were the contents of abscisic acid and volatile fatty acids of chain length C(6)-C(10). In A. sativa which did not possess postharvest dormancy there was no correlation between germination and inhibitor levels but in A. fatua the relationship between the content of fatty acid and dormancy was good. The loss of these fatty acids in dry storage by evaporation could explain after ripening.
燕麦属的不同种在收获前和收获后休眠水平上有显著差异。这些种为确定休眠是否与内源生长抑制剂水平有关提供了机会。对休眠水平不同的两种燕麦属种，即普通燕麦 Avena sativa L. 和野生燕麦 Avena fatua L. 的发芽率进行了评估，同时还评估了脱落酸和链长为 C(6)-C(10)的挥发性脂肪酸的含量。在没有收获后休眠的 A. sativa 中，发芽率与抑制剂水平之间没有相关性，但在 A. fatua 中，脂肪酸含量与休眠之间的关系很好。在干燥储存过程中通过蒸发损失这些脂肪酸可以解释后熟作用。
