摘  要:
应用TPS-1便携式光合测定仪,对入侵植物黄顶菊叶片的蒸腾速率和影响因子的日变化同步进行了测定,并采用灰色关联度分析的方法研究了黄顶菊叶片蒸腾速率与影响因子的关系。结果表明:黄顶菊蒸腾速率日进程呈"双峰"型,且峰值达1.05mmol.m-2.s-1。灰色关联度分析表明,气孔导度RS、叶室温度Tl、量子通量密度PFD是影响蒸腾速率的主导因子。

摘  要:
Diurnal variation of transpiration rate(Tr)and some influencing factors of Flaveria bidentis were determined by the TPS-1 stable photosynthetic analyzer,and using the method of grey relational degree analysis,the relationship between transpiration rate(Tr)and influencing factors was approached.The results indicated that daily curves of transpiration rate of Flaveria bidentis assumed double peak type,and the peak count reached to 1.05 mmol·m-2·s-1.By grey relational degree analysis,the major influencing factors were stomatal resistance(Dr)and internal leaf temperature(Tl),the next were photon flux density(PFD).
