摘  要:
[目的]探究几种常见菊科绿化植物的光合、蒸腾特性与抗旱性关系的比较。[方法]测量常见菊科小丽花、矮翠菊、黄晶菊与金盏菊的光合、蒸腾等生理特性,对其抗旱能力做出详细分析。[结果]对比3种双峰曲线绿化植物,小丽花的蒸腾速率日平均值最低,其净光合速率与蒸腾速率的比值(Pn/Tr)最高,其次为矮翠菊、而金盏菊Pn/Tr的值最低。气孔导度反映了气孔开张程度,小丽花、矮翠菊与金盏菊都在上午、下午出现2个峰值,但小丽花的第1个峰值出现在12:00。[结论]小丽花在参试绿化菊科植物中的抗旱能力最强。

摘  要:
[Objective] The research aimed to discuss relation of photosynthesis and transpiration to drought resistance among several ordinary feverfew greening plant.[Method] The physiological properties such as photosynthesis and transpiration of and feverfew such as Dahlia hybrid,Callistephus chinensis,Chrysanthemum mu1ticaule and Calendula offcinali and their ability of drought resistance were analyzed in detail.[Result] Comparison on 3 kinds of greening plants with double curve showed that D.hybrida had lowest daily averages of transpiration rate and highest ratio of photosynthesis rate to net transpiration rate(Pn/Tr),followed by C.chinensis and C.offcinalis was had lowest Pn/Tr value.The stoma conductance reflected the degree of stoma open and D.hybrida,C.chinensis and C.offcinalis all showed 2 peaks in a.m.and p.m.but D.hybrida had its first peak appeared on 12:00.[Conclusion] The ability of drought resistance of D.hybrida was strongest among the tested greening feverfew.
