Light-insensitive lettuce seeds, Lactuca sativa L. cv. Great Lakes, release esterases for a period following radicle protrusion. Very little or no enzymes are released prior to 24 hours or after 48 hours of germination. As compared to intact seeds, half-seeds readily release esterases and the release is not affected by far red irradiation. Bulk of the released esterases are derived from the endosperm tissue and presumably exists in the intact seed as a component of the extraembryonic fluid.
对光不敏感的生菜种子，即 Lactuca sativa L. cv. Great Lakes，在胚根伸出后一段时间内会释放酯酶。在发芽后 24 小时之前或之后 48 小时，几乎没有或没有酶被释放。与完整种子相比，半粒种子很容易释放酯酶，并且这种释放不受远红辐射的影响。释放的大部分酯酶来自胚乳组织，并且可能作为胚外体液的一部分存在于完整种子中。
