屋頂綠化植物不同佛甲草屬植物的耐熱性研究

時間:2019-06-09 08:05來源:畢業論文
選擇中國地區常用的七種屋頂綠化植物為實驗材料,分別是綠葉佛甲草、圓葉佛甲草、三七景天、垂盆草、金葉佛甲草、逆弁慶草、青鎖龍,測量了其葉片含水量與其在高溫脅迫下的相

摘要  選擇合適的屋頂綠化植物對屋頂綠化的效果與應用有著重要的現實意義。而高溫在眾多影響植物生長的因素中扮演了舉足輕重的角色,因此良好的耐熱性是優良的屋頂綠化植物必備條件之一。本實驗選擇中國地區常用的七種屋頂綠化植物為實驗材料,分別是綠葉佛甲草、圓葉佛甲草、三七景天、垂盆草、金葉佛甲草、逆弁慶草、青鎖龍,測量了其葉片含水量與其在高溫脅迫下的相對含水量,細胞膜透性,可溶性蛋白含量,通過各項生理指標數據的分析對其耐熱性進行研究。結果表明所有參與實驗的植物其生理生化指標都隨著溫度的改變而改變且不同植物之間差異明顯,在葉片水分的相關實驗方面,結果大致分為三個層次,綠葉佛甲草表現最好,三七景天、圓葉景天、垂盆草、青鎖龍次之,逆弁慶草、金葉佛甲草最差。在細胞膜透性方面,大小順序為青鎖龍>逆弁慶草>金葉佛甲草>圓葉景天>綠葉佛甲草>垂盆草>三七景天。在可溶性蛋白含量方面,表現為青鎖龍>三七景天>逆弁慶草>金葉佛甲草>圓葉景天>綠葉佛甲草>垂盆草。36082

Study on Heat Resistance of Different Species of the Genus Sedum
Abstract  Choosing the appropriate roof greening plants has important practical significance for the effect and application of roof greening.The high temperature plays an important role in many factors that affect the growth of plants, so good heat resistance is one of the essential conditions for the roof greening plants growing.In order to expore the heat resistance of roof greening plants and study the adaptability of the plant to high  temperature environments,Sedum lineare’lvye’, Sedum lineare’yuanye’, Sedum sieboldii, Sedum spetabiles, Sedums armentosum Bunge, Sedum lineare ‘jinye’, Sedum reflexum, Sedum crassula.suitable for roof greening were as the test materials in the experiment.The relative water content ,Cell membrane and The content of soluble protein of above plants were tested at different heat treatment conditions.The results showed that:All the physiological and biochemical parameters of the plants participating in the experiment changed with the temperature and the differences were obvious,The results of leaf moisture,were roughly pided into three levels ,Sedum lineare ‘lvye’ showed best,  Sedum sieboldii, Sedum lineare ‘yuanye’, Sedum spetabiles, Sedum crassula were worse, Sedum reflexum and Sedum lineare ‘jinye’ showed worst.The rank of cell membrance is Sedum crassula, Sedum reflexum, Sedum lineare ‘jinye’, Sedum lineare ‘yuanye’, Sedum lineare ‘lvye’, Sedum spetabiles ,Sedum sieboldii. The rank of the content of soluble protein of above plants is Sedum crassula, Sedum sieboldii, Sedum reflexum, Sedum lineare ‘jinye’ ,Sedum lineare ‘yuanye’, Sedum lineare ‘lvye’ ,Sedum spetabiles. 源¥自%六^^維*論-文+網=www.aftnzs.live
