Abstract

desired to establish a system for efficient environmental control based on physiological functions of crops. Translocation of photosynthate from leaves to fruits is a major physiological determinant for size and sugar content of strawberries. It is therefore essential to clarify the response of photosynthate loading to surrounding environment. In this study, we focused on light condition which strongly influences the photosynthesis, and analyzed effects of irradiation on dynamics of photosynthate loading. Furthermore, aiming at the estimation of dynamics of photostnthate loading in cultivation field, we simulated daily amount of photosynthate loading by kinetic model using a saturable Michaelis-Menten component in combination with an unsaturable component obeying first-order kinetics.

源叶光照条件对草莓光合作用负荷的影响
希望建立一个基于作物生理功能的高效环境控制系统。光合产物从叶片向果实的转运是草莓大小和含糖量的主要生理决定因素。因此,阐明光合产物负荷对周围环境的响应是十分必要的。本研究以影响光合作用的光照条件为研究对象,分析了光照对光合作用负荷动态的影响。此外,为了估算栽培田间光合产物的负荷动态,我们采用饱和Michaelis-Menten组分与一阶不饱和组分相结合的动力学模型模拟了光合产物的日负荷。
