Changes in the major chloroplast pigments of pigment-deficient genotypes of soybeans were studied as a function of leaf age and plant age. The trends of pigment development are plotted as a function of relative leaf age at two periods of plant development. Comparisons are made between aging leaves from different nodes and leaves of different ages from the same node. In addition, trends of pigment development are expressed as a ratio of pigment-deficient/normal genotypes for five different genotypes and seven sampling periods. Those genotypes that exhibit a lag in production of pigments during leaf development show a similar lag in overall plant pigment development.
研究了大豆色素缺乏基因型的主要叶绿体色素随叶龄和植株年龄的变化。色素发育趋势以植株发育两个阶段的相对叶龄为函数绘制。对不同节位的衰老叶片和同一节位不同年龄的叶片进行了比较。此外,色素发育趋势以五种不同基因型和七个采样期的色素缺乏/正常基因型之比表示。那些在叶片发育过程中色素产生滞后的基因型在整个植株色素发育中也表现出类似的滞后。
