The response of whole leaf photosynthetic rate in Fragaria virginiana to sudden changes in photosynthetically active radiation (PAR) is described. Two components of the response, consisting of a time lag and time constant, are estimated under varying PAR changes for plants grown under two different light regimes. Both the time lag and time constant are found to vary with PAR but not with growth light regime. A model of Thornley for leaf photosynthetic response is refuted and an alternative form is discussed.
本文描述了弗吉尼亚草莓全叶光合速率对光合有效辐射（PAR）突然变化的响应。在两种不同光照条件下生长的植株中，根据 PAR 的变化情况，对响应的两个组成部分（时滞和时间常数）进行了估算。发现时滞和时间常数均随 PAR 而变化，但与生长光照条件无关。Thornley 的叶片光合响应模型被否定，并讨论了一种替代形式。
