( 3 ) wheatgrass could reduce water dissipation by shutting up stoma and let some leaves wither
3 、冰草植株在乾旱條件下關閉氣孔，以減少水分散失，葉片萎蔫，以減少蒸騰面積。Banana seedlings inoculated with fusarium oxysporum f. sp. cubense race 4 appeared some symptoms, such as yellow leaves, browning corm tissue ( occured in the earlier period ), wilting leaves, browning corm and pesudostem tissue, blacking roots ( occured in the middle period ), and wilting, dying plants ( occured in the latter period )
摘要用枯萎病菌4號生理小種接種香蕉苗后，觀察發現：香蕉苗在發病初期出現了黃葉、球莖組織變褐癥狀；發病中期出現了葉片萎蔫、球莖組織變褐、假莖可見斑點狀或線條狀褐色病變、根變黑褐癥狀；發病後期出現了植株萎蔫、枯死等癥狀。Thirdly, this paper compared the different responses of plants to these two stresses, the change of the defensive enzyme activity and the rate of losing water of leaves was different at two different stresses. the rate of losing water of leaves at drought stress was more rapid than that at salt stress, the leaves would wither and the change of activity of enzymes notably at drought stress, these results showed that the damage to plants was result from the oxidation at drought stress. at salt stress, the content of relative water of leaves changed slightly as well as did the activity of enzymes, these results showed that the damage to plants was caused by poison of ion and lack of nutrition
三、通過研究兩種冰草植物對兩種脅迫的反應指出乾旱脅迫和鹽脅迫通過不同的途徑對植物進行傷害，主要表現在葉片的失水速率和保護酶活性的變化，乾旱脅迫短時間內葉片失水速率很快，葉片萎蔫，引起保護酶活性顯著變化，表明乾旱脅迫主要是通過氧化脅迫對植株造成傷害，而鹽脅迫下葉片相對含水量幾乎保持不變，表明鹽脅迫對植物的傷害主要通過離子毒害和營養虧缺造成。To make the ti plasmid pbi121 - nhap for transformants the tobacco ( nc89 ), at the same time to make the pemu - mcs - n - nhap and pwubi. tml - nhap for transformants the yan wheat 18. we getted 4 transgenic tobaccos, measured the ability of salt tolerance by treatment in 150 mmol / 1 nacl, found that the transgenic tobaccoes can growth and the control tobaccos ca n ' t
通過比較轉synnhap基因煙草與對照煙草的耐鹽性，發現4株轉synnhap基因的煙草再生苗在含150mmnacl的培養液中處理兩周后，植株外觀無明顯變化，葉片生長情況正常，而對照植株的生長則受到抑制，葉片明顯萎蔫、失綠並最終脫落。分享友人
