Photosynthetic oxygen evolution per milligram of chlorophyll in Chlorella vulgaris varies with the age of the culture. The rate of oxygen evolution is low in the starting cells, it rises to a maximum after 24 hours of growth and then declines to the initial low value after 72 to 90 hours. These changes in photosynthetic competence of chlorophyll in Chlorella are paralleled by changes in alpha-linolenate per milligram of chlorophyll. In general the magnitude of the photosynthetic competence of chlorophyll is directly proportional to the magnitude of the ratio of alpha-linolenate to chlorophyll, regardless of whether high ratios are due to high alpha-linolenates or low chlorophyll values. This relationship holds when the cultures are grown either under continuous or intermittent illumination.
小球藻每毫克叶绿素的光合放氧能力随培养时间而变化。起始细胞的放氧速率较低，培养 24 小时后上升到最大值，然后在 72 至 90 小时后下降到初始低值。小球藻叶绿素的光合能力的这些变化与每毫克叶绿素的α-亚麻酸的变化平行。一般来说，叶绿素的光合能力的大小与α-亚麻酸与叶绿素的比值成正比，无论高比值是由于高α-亚麻酸还是低叶绿素值引起的。当在连续或间歇光照下培养时，这种关系都成立。
