Adaptability Research Of Common Green Plants For Roof Greening

This test used2a plant seedlings as materials,the experiment was carried out on the roof the natural environment directly, by observing and determinationing the condit ion of physiological changes of18species of greening plants under the roof natural e nvironment, select materials that suitable for roof greening plants in Shanxi Province. The results show that:(1)From the metrics of plant leaf SOD enzyme activity changes:Prunus pseudocerasus、 Berberis thunbergii showed better adaptability to the roof environment, followed by Euonymus kiautshovicus Maxim、Robinia pseudoacacia、Prunus armeniaca、Fraxinus chinensis、Jasminum nudiflorum、Euonymus; the last isSabina vulgaris、Salix matsudana、 Fontanesia fortunei、Ulmus pumila、Populus tomentosa、Zizyphus jujuba、Koelreuteria paniculata、Platycladus orientalis、Ligustrum vicaryi、Sophora japonica.(2)From the indicators of plant leaves malondialdehyde (MDA) content changes: Euonymus kiautshovicus Maxim、Sabina vulgaris、Robinia pseudoacacia、Prunus armeniaca、Fontanesia fortunei、Ulmus pumila、Populus tomentosa、Fraxinus chinensis、 Zizyphus jujuba、Koelreuteria paniculata、Platycladus orientalis、Ligustrum vicaryi、Sophora japonica、Jasminum nudiflorum showed better adaptability to the roof environment; followed by Ulmus pumila、Berberis thunbergii;the last is:Prunus pseudocerasus.(3)From the metrics of plant leaf free proline content changes:under drought stress environment, Prunus pseudocerasus and Ulmus pumila, its osmotic regulation ability is stronger, Sabina vulgaris、Euonymus kiautshovicus、Euonymus kiautshovicus Maxim、 Robinia pseudoacacia take the second place, Salix matsudana Prunus armeniaca、 Fontanesia fortunei、Populus tomentosa、Fraxinus chinensis Zizyphus jujuba、Koelreuteria paniculata、Berberis thunbergii、Ligustrum vicaryi、Sophora japonica、Jasminum nudiflorum, its regulation ability is weak.(4)From the index of plant leaf soluble sugar content changes:As the extent of the natural stress increased,the leaf soluble sugar content of Fraxinus chinensis、Populus tomentosa、 Euonymus kiautshovicus Maxim at high level, under the roof afforestation environment, its have good adaptability; followed by Prunus pseudocerasus、Salix matsudana、Ulmus pumila、Fontanesia fortunei、Zizyphus jujuba、Koelreuteria paniculata、Sophora japonica、 Jasminum nudiflorum. Again for Platycladus orientalis、Ligustrum vicaryi、Robinia pseudoacacia、Sabina vulgaris、Prunus armeniaca、Berberis thunbergii、Euonymus kiautshovicus.(5)Judging from the index of plant leaf relative conductivity:Euonymus kiautshovicus Maxim、Ulmus pumila、Populus tomentosa、Fraxinus chinensis、Zizyphus jujuba showed better adaptability to the roof environment; followed by Salix matsudana、Fontanesia fortunei、Platycladus orientalis、Euonymus kiautshovicus; again for Sabina vulgaris、 Robinia pseudoacacia、Koelreuteria paniculata、Ligustrum vicaryi; on the roof environment, Prunus armeniaca、Prunus pseudocerasus、Berberis thunbergii, its adaptability is poorer.Through comprehensive analysis of the resistant physiological indexes:Euonymus kiautshovicus Maxim、Ulmus pumila、Populus tomentosa、Fraxinus chinensis were best for roof environment adaptability,its can be used as plant materials of choice for roof greening of Shanxi Province; on the roof environment, Zizyphus jujuba、Sophora japonica、Jasminum nudiflorum、Salix matsudana Fontanesia fortunei、Euonymus kiautshovicus、Ligustrum vicaryi、Koelreuteria paniculata、Robinia pseudoacacia、Sabina vulgaris、Platycladus orientalis have certain adaptability, through certain cultivation management can also reach a certain greening effect; on the roof environment, Prunus armeniaca、Prunus pseudocerasus and Berberis thunbergii, its adaptability were poorer.In roof greening plants selection, we don’t recommend choose Prunus armeniaca、Prunus pseudocerasus and Berberis thunbergii as roof greening plant materials.
