Plastids in conifers and angiosperms grown without light have different pigment composition. Angiosperm etioplasts have prothylakoids lacking chlorophyll, while coniferous etiochloroplasts synthesize chlorophyll and undergo only limited development. Their thylakoids are slightly stacked and show photosynthetic activities. The present study deals with the photoconversion of protochlorophyllide, the formation of chlorophyll-protein complexes and stepwise development of photosystem II upon illumination of dark-grown seedlings of Picea abies. We conclude from the results that insuficiency of stacking of thylakoids limits chloroplast development in the dark and light-induced development of chloroplasts is closely associated with the synthesis of new photosynthetic units and the magnification of photosystem I and II units.

无光生长的针叶树和被子植物的质体具有不同的色素组成。被子植物的始质体具有缺乏叶绿素的类原囊体，而针叶植物的始叶绿体合成叶绿素并且只经历有限的发育。它们的类囊体略有堆叠，并显示光合活性。本文研究了欧洲云杉（Picea abies）暗生长幼苗在光照下原叶绿素的光转化、叶绿素-蛋白质复合物的形成以及光系统II的逐步发育。我们的结论是，类囊体的堆积不足限制了叶绿体在黑暗中的发展和光诱导的叶绿体的发展是密切相关的新的光合单位的合成和光系统I和II单位的放大。
