不同光照对蝴蝶花光合特性及生长发育研究
A study on photosynthetic characteristics and growth and development of Iris japonica under different illumination
摘要
Abstract
Adaptability of Iris japonica under different illuminations was studied with the photosynthetic characteristics measured with a Li-6400 photosynthesis system. The Chl a/Chl b, net photosynthetic rate, stomatal conductance, transpiration rate and intercellular CO2 concentration decreased with less light on the plants, and the light compensation point, dark respiration rate, the CO2 compensation point also decreased, but the car-boxylation efficiency increased as a mechanism of physiological adaptability to light decreasing. The adaptability to light was wide because the light compensation point was 5. 18 - 12. 05 μmol/(m2 · s) and the light saturation point was higher (about 1 000 μmol/m2 · s); the CO2 compensation point was 54. 84 - 58. 45 μmol/mol and the CO2 saturation point was about 970 μmol/mol; the plants under bamboo forest had bigger leaf area and better flowering than that of other community patterns, but the plants could grow under the three community patterns.关键词
