After 7 days of germination in the dark, the three sections of pea seedlings studied (cotyledons, stems, and young leaves) are rich in linoleic acid; after illumination of the seedlings a very significant increase in linolenic acid is observed in the young leaves section, whereas only small variations are noted in the fatty acid composition of the other sections. The increase in linolenic acid results from the increase in galactolipid content of the young leaves; these already linolenic acid-rich galactolipids are present but only in small amounts in the etiolated seedlings (10% of total lipid).Variations in composition of the other lipid classes (phospholipids and neutral fats) were also studied. The possibility of fatty acid transport from the cotyledons toward the young leaves during the synthesis of the photosynthetic apparatus is discussed.
豌豆幼苗的三个研究部位（子叶、茎和嫩叶）在黑暗中培养 7 天后富含亚油酸；幼苗受光后，嫩叶中亚麻酸含量显著增加，而其他部位的脂肪酸组成只有很小的变化。亚麻酸的增加是由于嫩叶中半乳糖脂含量的增加；这些半乳糖脂本身就富含亚麻酸，但在黄化幼苗中含量很少（占总脂质的 10%）。其他脂质类（磷脂和中性脂肪）组成的变化也进行了研究。讨论了在光合器官合成过程中，脂肪酸从子叶向嫩叶运输的可能性。
