菠萝寒害模型及其理论分析

本文刊用耗散结构理论,根据菠萝寒害机理建立了寒害模型,并对该摸型作了动力理论分析。结果表明,菠萝寒害状态依赖于光合作用、淀粉水解和呼吸作用这三个过程的反应速率系数,当它们满足采一特定条件时,反应中间产物出现振荡行为,寒害减轻;否则寒害将加剧。这一特点类似于细胞生物膜寒害,最后对菠萝寒害作了数值模拟。

A Model for Pineapple Cold lnjury and Theoretical Analysis

This paper proposes a model for pineapple cold Injury(PCI)based on the mechanisms of PCI using the dissipative structure theory, and the model is dynamiclly analysed. It is shown that the states of PCI depend on the rates of photosynthesis, amylum hydrolysis and respiration. We find that the oscillatory behaviour may occur when the rates satisfy certain conditions, and it will decrease FCI. This feature of PCI is similar to that of biomembranes of a cell cold injury. Finally, the numerical simulation for PCI is made.
