摘  要：
基于对上海市典型公园绿地的实地调研,选取 10 种槭属植物为研究对象,在遮阴率分别为 0%、30%和55%的条件下,通过测定分析其形态特征、光响应曲线、叶片气体交换参数、叶绿素荧光参数等指标,探讨不同程度的遮阴处理对不同树种叶片日灼伤害的影响.结果表明:在不同遮阴处理下,参试树种叶片的日灼伤害程度存在一定差异,遮阴能有效减轻不同树种叶片的日灼伤害程度;不同遮阴处理对不同树种光响应曲线、叶片气体交换参数和叶绿素荧光参数影响显著.综合评价表明:依据参试树种在不同遮阴处理下的生理表现和形态表现(差异依次减小),其叶片日灼伤害可划分为4 种类型,其中A类包括复叶槭和羽毛枫,B类包括夕阳红、秋火焰、鸡爪槭和挪威槭,C类包括三角枫、五角枫,D类包括三季红和橙之梦.该研究结果可为园林树种的科学选择和合理规划提供理论依据.

摘  要：
Based on a survey of the green space in major parks in Shanghai,10 species ofAcerwere selected as research materials.Under the conditions of shading rates of 0%,30% and 55% respectively,the effects of different shading treatments on sunburn injury of leaves of different tree species were discussed by measuring and analyzing the morphological characteristics,light response curve,leaf gas exchange parameters and chlorophyll fluorescence parameters.The results showed that there were certain differences in the degree of sunburn injury to the leaves of the tested tree species under different shading treatments,and shading could effectively reduce the degree of sunburn injury to the leaves of different tree species.Different shading treatments had significant effects on light response curves,leaf gas exchange parameters and chlorophyll fluorescence parameters of different tree species.The comprehensive evaluation showed that based on the physiological and morphological performance(the differences decreased in order) of the tested tree species under different shading treatments,their sunburn injury to the leaves could be divided into 4 types.Among them,class A includedA.negundo'Variegatum' and A.palmatum 'Atropurpureum',class B included A.rubrum' Red Sunset',A.rubrum' Autumn Blaze',A.palmatumand A.platanoides 'Crimson King',class C included A.buergerianumandA.mono,and class D included A.palmatum' Sanjihong' andA.palmatum' Orange Dream'.The research results could provide a theoretical basis for the scientific selection and rational planning of garden tree species.
