将 S. bicolor SD-102 成熟植株的表皮蜡质与同一品种的圆锥花序和幼苗在第 4-5 叶生长阶段的表皮蜡质进行比较。 SD-102圆锥花序的蜡成分与成熟叶片和叶鞘的蜡成分有很大不同。游离脂肪醇是 SD-102 幼苗蜡的主要类别，C32 是醇和醛的主要同系物。出于比较目的；对生长到抽雄阶段的另外 2 个 S. bicolor 品种 Alliance A 和 Martin A 的整个植株的表皮蜡质进行了分析。主要蜡成分是游离脂肪酸。醛、游离醇和游离脂肪酸的典型链长为C28和C30。对羟基苯甲醛不是所研究的高粱品种的蜡成分。
Epicuticular wax from mature plants of S. bicolor SD-102 was compared with that from panicles and seedlings of the same variety at the 4th-5th leaf stage of growth. The compositon of wax from SD-102 panicles was quite different from that of mature leaf blades and sheaths. Free fatty alcohols were the dominant class of wax from SD-102 seedlings and C32 was the major homologue of alcohols and aldehydes. For comparison purposes; the epicuticular waxes from whole plants of 2 other S. bicolor varieties, Alliance A and Martin A, grown up to the tasseling stage, were analyzed. The major wax components were free fatty acids. The typical chain lengths of aldehydes, free alcohols and free fatty acids were C28 and C30. p-Hydroxybenzaldehyde was not a wax component of the studied varieties of sorghum.
