摘要:
为了加深对药用植物光合生理特性的认识，对其进一步科学种植提供理论依据，采用Li6400便携式光合测定系统，对玫瑰、枇杷、杜仲、厚朴的光合速率日变化、季节变化、光响应曲线和CO2响应曲线进行了测定。结果表明4种药用植物的光合速率日变化均呈“双峰”曲线，表现出明显的光合“午休”现象。年平均光合速率为枇杷>杜仲>玫瑰>厚朴，光合能力为枇杷>厚朴>杜仲>玫瑰。通过增加CO2浓度有可能提高4种药用植物的光合速率。西北林学院学报22卷第6期刘奇峰等4种药用植物光合特性的研究
Abstract:
To further study the photosynthetic characteristics of medicinal plants, and provide theory basis for their scientific planting, the photosynthetic rates, light response curves of photosynthesis and CO2 response curves of four medicinal plants, namely Rosa rugosa, Eriobotrya japonica , Eucommia ulmoides and Magnolia officinalis , were measured by Li6400 portable photosynthesis system. The results were as follows The diurnal courses of photosynthesis were double peaked and they showed the midday depression of photosynthesis obviously, which was caused by the stomatalimited under high temperature and light intensity. The descending order of annual photosynthetic rates was Eriobotrya japonica, Eucommia ulmoides, R.rugosa and M.officinalis, and their photosynthetic capabilities decreased order is Eriobotrya.japonica, M.officinalis, Eucommia.ulmoides and R.rugosa. From these two curves, we can conclude that it is possible to improve the photosynthetic rates of these four medical plants by CO2 enrichment.
