- Abstract:
- Taking four typical green plants which were Cinnamomum camphora (L.) presl, Osmanthus fragrans (Thunb.) Lour., Ilex chinensis Sims and Rhododendron simsii Planch. as experimental samples through three years, we inverstigated and compared the dust retention capacities and physiological properties of these typical green plants in Nanning City. The results showed that the dust retention capacities of different typical plants in Nanning existed a significant difference (p < 0.05), which showed the sequence: Cinnamomum camphora (L.) presl > Ilex chinensis Sims > Osmanthus fragrans (Thunb.) Lour. > Rhododendron simsii Planch. Seasonal variation significantly influenced the dust-retention capacity, it was bigger in spring and winter, while it was smaller in summer and autumn, which showed the order: Cinnamomum camphora (L.) presl > Ilex chinensis Sims > Osmanthus fragrans (Thunb.) Lour. > Rhododendron simsii(Planch) in the same season. The dust particle sizes of different typical plants in Nanning mainly ranged from 2.5 μm to 100 μm, of which less than 100 μm accounted for more than 99%. The power function relationship between specific leaf weight (x) and dust detentions (y) was the significant (p < 0.001), it could be seen that the larger specific leaf weight was, the larger dust detention was. The protective enzyme (SOD, POD, CAT), the non-protective enzyme (PAL, PPO) activity, chlorophyll a, chlorophyll b, soluble protein and soluble sugar of different typical plants in Nanning showed the sequence: Cinnamomum camphora (L.) presl > Ilex chinensis Sim s> Osmanthus fragrans (Thunb.) Lour. > Rhododendron simsii(Planch). Correlation analysis showed that the dust retention capacities of different typical plants were significantly or extremely significantly positively related to the leaf enzymatic activities.
