Cadmium ions introduced at concentration of 30 ppm to the cultivation medium of synchronously growing Chlorella vulgaris decreased concentration of chlorophylls a and b, carotenes alpha and beta and lutein at various stages of the cell cycle, while at concentration of 1 ppm synthesis of the photosynthetic pigments was stimulated. The pigment content in the cadmium treated cells was related to the morphometrically determined changes in the size and shape of the cells.
以30 ppm的浓度引入到同步生长的普通小球藻培养基中的镉离子，在细胞周期的各个阶段均降低了叶绿素a和b、α-胡萝卜素、β-胡萝卜素以及叶黄素的浓度，而在1 ppm的浓度下，光合色素的合成受到刺激。镉处理细胞中的色素含量与通过形态测量确定的细胞大小和形状变化有关。
