Abstract

Changes in weight, water content, nucleic acids, nucleotides, carbohydrates, lipids, nitrogenous and phosphorus compounds in embryo and gametophyte of Douglas fir seeds (Pseudotsuga menziesii Franco) were studied at 6 stages of germination. Lipids, proteins, and reserve phosphorus compounds in the gametophyte were utilized for the synthesis of carbohydrates, structural components, and soluble compounds in the seedling.The general quantitative metabolic changes that occur during germination of Douglas fir seeds are comparable to those known for angiosperm seeds.

摘要

在花旗松种子(北美黄杉)萌发的6个阶段,研究了胚和配子体中重量、含水量、核酸、核苷酸、碳水化合物、脂质、含氮和含磷化合物的变化。配子体中的脂质、蛋白质和储备磷化合物被用于合成幼苗中的碳水化合物、结构成分和可溶性化合物。花旗松种子萌发过程中发生的一般定量代谢变化与被子植物种子已知的变化相当。
