在田间条件下，研究了不同氮素和温度条件下高羊茅（Festuca arundinacea Schreb）叶片伸展速率的变化。当氮素不限制植物生长时，LER与温度密切相关。LER和温度之间的两个不同的关系，一个营养生长和生殖期。用Gompertz函数描述的这些关系在8 ° C以下呈指数关系，在8 ° C以上呈线性关系。它们使得计算与植物生长的非限制性N条件相对应的最佳LER成为可能
The leaf extension rate (LER) of tall fescue (Festuca arundinacea Schreb,) was studied in the field under various nitrogen and temperature regimes. The LER was closely related to temperature when N was not limiting plant growth. Two distinct relationships between the LER and the temperature were obtained, one for vegetative growth and one for the reproductive period. These relationships, described by a Gompertz function, were exponential at temperatures below 8 o C and linear at temperatures above 8 o C. They made possible the calculation of an optimal LER corresponding to non-limiting N conditions for plant growth
