Light-grown 7-day-old wheat seedlings (Triticum aestivum, var. Maris Dove) showed an increase of 200% in plastids per cell between 1.7 and 4.5 centimeters from the leaf base. This increase was the result of divisions of young chloroplasts at various stages of development, and was well separated in distance, and therefore in time from the region of cell division in the basal meristem. [(3)H]Thymidine was incorporated into plastid DNA throughout the zone of plastid division, but not above it.
在距叶片基部 1.7 至 4.5 厘米处，光培养的 7 天龄小麦幼苗（Triticum aestivum，var. Maris Dove）的每个细胞中的质体数量增加了 200%。这种增加是由于不同发育阶段的年轻叶绿体的分裂所致，并且在距离上和时间上都与基部分生组织的细胞分裂区域分开。[（3）H]胸腺嘧啶核苷被掺入整个质体分裂区域的质体 DNA 中，但不在其上方。
