| 摘 要： | 温度对组培苗的生长发育具有重要的作用，提高光合光量子通量密度会引起微环境温度强烈变化。为探讨光合光量子通量密度对组培微环境温度的影响，测定了不同光合光量子通量密度下，组培环境中各主要测点温度的历时变化值，分析了组培微环境温度变化的影响因素和热平衡过程，建立了组培微环境的热平衡模式。实验结果表明增高光合光量子通量密度所导致的微环境温升高于经验估测值，必须采取措施降低微环境温度，进一步的分析指出调控组培箱内气温和支承板温度是降低组培微环境温度的有效措施。

| Abstract: | Temperature plays a vital role in the growth of plantlets in vitro. To enhance the photosynthetic photo flux density can cause a drastic change in temperature. To probe the effects of light intensity on temperature in the microenvironment, changes in temperature of several selected points were measured during different photosynthetic photo flux densities (PPFD). Changes in temperature and patterns of heat balance were analyzed. The pattern of heat balance for microenvironment in vitro was constructed. The results of the experiment showed that the increase in temperature resulting from the improvement in PPFD was higher than our expectations. Therefore, it is necessary to decrease the temperature in the micro-environment. The analysis shows that the temperature control for the bench and the gas inside the culture box offers an effective way to decrease temperature in the microenvironment. |
