在玉米中，营养阶段变化的时间与对某些害虫和环境胁迫的反应有关。普通锈病是美国中北部甜玉米最严重的病害。甜玉米杂交种对普通锈病的抗性不同，评价营养相变性状。杂交种间营养生长阶段变化及对普通锈病的抗性均存在显著差异。某些杂交种表现出快速过渡（两叶内）从少年到成年植被，而其他人则表现出长期的过渡（四叶内）。在本试验所评价的商品甜玉米杂交种中，营养期转变性状与普通锈病严重程度之间没有显著的相关性。
In maize, timing of vegetative phase change has been implicated in the response to certain pests and environmental stresses. Common rust is the most serious disease of sweet corn in the north central United States. Sweet corn hybrids differing for resistance to common rust were evaluated for vegetative phase change traits. There were significant differences among hybrids for all vegetative phase change traits measured, as well as resistance to common rust. Certain hybrids displayed rapid transition (within two leaves) from juvenile to adult vegetation, while others displayed prolonged transition (within four leaves). There were no significant correlations between vegetative phase change traits and common rust severity among the commercial sweet corn hybrids evaluated in this experiment.
