本文研究了鳞<i>毛蕨（Dryopteris filix-mas</i>）和荚果蕨<i>（Matteuccia struthiopteris）</i>叶片中总脂、糖脂、磷脂和一种甜菜碱脂（DGTS）的分布。形成芽或“高音谱号”的胚小叶的脂质组成，以及完全打开的叶子的脂质组成在整个生长季节都在变化。裂叶和成熟叶中DGTS的最大量在季节开始时检测到。到盛夏，DGTS含量下降，在完全开放的叶片中降至零，然后再次增加。在10月采集的谱子中DGTS的量与5月采集的谱子相比，在<i>鳞毛蕨属的</i>情况下稍高，而在<i>Matteuccia struthiopteris</i>的情况下几乎低两倍。在整个生长季节的裂缝和成熟叶片中所含的极性脂质之间的比例进行了测定。
The distribution pattern of total lipids, glyco- and phospholipids, and one betaine lipid (DGTS) in the fronds of the ferns <i>Dryopteris filix-mas</i> and <i>Matteuccia struthiopteris</i> was studied. The lipid composition of the embryo leaflets forming a bud, or “treble clef”, and that of fully opened leaves changed throughout the growth season. The maximum amount of DGTS in clefs and mature leaves was detected at the beginning of the season. By midsummer, the DGTS content decreased, dropping to zero in the fully opened leaves, and then increased again. The amount of DGTS in the clefs collected in October versus those collected in May was somewhat higher in the case of <i>Dryopteris filix-mas</i> and almost twofold lower in the case of <i>Matteuccia struthiopteris</i> . The ratio between polar lipids contained in the clefs and mature leaves throughout the growth season was determined.
