Influence of NaCL Stress on Delayed Luminescence(DL) from Leaves

The influence of different concentration NaCL treatment on delayed luminescence (DL) from Lotus leaves has been investigated by BPCL. The results indicate that in the condition of the lower concentration treatments, the initial strength and attenuation parameters of DL firstly increase and then decrease with treating time going on; that in the condition of higher concentration treatments the initial strength and attenuation parameters of DL continuously decrease; and that in the same treating time, the initial strength and attenuation parameters of DL vary differently with concentration adding , and they arrive the biggest ones specially in 72 h with 1% concentration and in 96 h with 0.1% concentration.
