Disruption of preparations of intact etioplasts isolated from wheat (Triticum aestivum L.) leaves in the dark leads to an increase in the level of extractable gibberellin-like (GA-like) activity. Irradiation of disrupted preparations with red light causes an alteration in the Rf of part of the GA-like activity. A study of sub-etioplast fractions prepared by gradient centrifugation indicates that the phytochrome and the GA-like substances are associated principally with the etioplast envelope.
在黑暗中分离的完整质体在制备过程中受到破坏，会导致可提取的赤霉素类似物（GA 类似物）活性增加。用红光照射破碎的制剂会导致部分 GA 类似物活性的 Rf 值发生变化。通过梯度离心制备亚质体级分的研究表明，光敏色素和 GA 类似物主要与质体被膜相关。
