The protoheme content of etiolated, greening, and fully greened bean (Phaseolus vulgaris L. var. Light Red Kidney) leaves has been studied. The protoheme level in etiolated and fully greened leaf tissue stays relatively constant from age 7 to 14 days. In agreement with the studies reported for barley (Castelfranco and Jones 1975 Plant Physiol 55: 485-490), the protoheme content of greening bean and barley (Hordeum vulgare var. Larker) leaves does not change appreciably during the first 9 hours of illumination, but the level rises significantly by the 24th hour of illumination (cf. Hendry and Stobart 1977 Phytochemistry 16: 1545-1548). This increase also occurs in seedlings returned to the dark for 24 to 48 hours following a 10-minute pulse of light. These results demonstrate a limited correlation with previous studies on the development of b-type cytochromes during greening of these tissues (Gregory and Bradbeer 1973; Planta 109: 317-326).
研究了黄化、变绿和完全变绿的菜豆（Phaseolus vulgaris L. var. Light Red Kidney）叶片中的原血红素含量。在 7 到 14 天的年龄内，黄化和完全变绿的叶片组织中原血红素水平保持相对稳定。与大麦（Castelfranco 和 Jones 1975 Plant Physiol 55: 485-490）的研究一致，变绿的菜豆和大麦（Hordeum vulgare var. Larker）叶片中原血红素的含量在光照的前 9 小时内没有明显变化，但在光照的第 24 小时显著升高（参见 Hendry 和 Stobart 1977 Phytochemistry 16: 1545-1548）。在经过 10 分钟的光脉冲后，幼苗返回黑暗中 24 到 48 小时，也会发生这种增加。这些结果与之前关于这些组织变绿过程中 b 型细胞色素发育的研究有一定的相关性（Gregory 和 Bradbeer 1973；Planta 109: 317-326）。
