The Impact Of Anatomical Structure For9Kinds Of Plants At The Stress Of Drought And Automobile Exhaust

This experiment used Lonicera maackiiy Cornus alba L.、Euonymus sacrosancta Koidz.、 Syringa microphylla Diels、Ligustrum suave (Kitag.) Kitag.、Cerasus glandulosa、 Weigela florida ’Red Prince’、Salix integra’Hakuro Nishilci’、Prunus padus L. as test material.This experiment use the technique of paraffin section and light microscope. Observe these leaves of anatomic structure and the characteristics of the resistance of the drought and automobile exhaust.Determined the thickness of leaf、the thickness of epicuticle、the thickness of lower epidermis、thickness of palisade tissue、thickness of spongy tissue、 palisade tissue/spongy tissue、thickness of horny layer、the degree of leaf close、the degree of leaf loose. And made the measure nine quota mubordinate function values, in order to compare the resistance capability. The results show that:Nine trees all have many kinds of anatomic structure, all have palisade tissue、spongy tissue、cuticula, etc; Under the stress of the drought and automobile exhaust, the structure of the leaves have many different degree changes. Palisade tissue gradually thickening、Spongy tissue gradually pinching、cuticula gradually thickening, etc; The sort of the nine shrubs under the stress of the drought:Cornus alba L.>Salix matsudana> Syringa microphylla> Weigela florida> Lonicera maackii> Cerasus glandulosa>Ligustrum suave>Euonymus sacrosancta> Padus virginiana ’Schubert’; The sort of the nine shrubs under the stress of the automobile exhaust:Cornus alba L.> Cerasus glandulosa> Ligustrum suave> Salix matsudana> Lonicera maackii> Euonymus sacrosancta> Padus virginiana ’Schubert’> Syringa microphylla> Weigela florida...
