MeasurementofCarbonFixationRatesinLeafSamples
Generation of a Light Curve To address the hypothesis concerning photosynthetic efficiency it is necessary to expose sun and shade leaves to a range of light intensities long enough for them to fix significant amounts of carbon. It is necessary to expose identical surface areas under favorable conditions which are identical for all leaves except for light intensity (the experimental variable). A means of ......阅读全文

光合碳循环-(photosynthetic-carbon-cycle)
光合作用中碳同化(二氧化碳转化为糖或其磷酸酯)的基本途径。又称卡尔文循环、还原戊糖磷酸循环、还原戊糖磷酸途径。在绿色植物、蓝藻和多种光合细菌中普遍存在。其他碳同化途径如 C4 途径和 CAM途径(见景天科酸代谢)所固定的 CO2 ,最终仍须通过光合碳循环才能被还原成糖。因此它是地球上绝大部分有机物

固氮作用(nitrogen-fixation)
分子态氮被还原成氨和其他含氮化合物的过程。自然界氮(N2 )的固定有两种方式:一种是非生物固氮,即通过闪电、高温放电等固氮,这样形成的氮化物很少;二是生物固氮,即分子态氮在生物体内还原为氨的过程。大气中90%以上的分子态氮都是通过固氮微生物的作用被还原为氨的。生物固氮是固氮微生物的一种特殊的生理功
