The shrinking and swelling in plant stem diameter was closely related to the crop water status within plant, the parameters derived from stem diameter measurements were reliable plant water status indicators, which could reflect crop water deficits sensitively, duly and accurately
摘要植株莖直徑的收縮和膨脹與作物體內水分狀況密切相關，莖直徑變化測量參數能實時、靈敏地反映作物水分虧缺程度。In natural light intensity condition, the content of aba is the highest, but the contents of ga, iaa, zrs reduce, which is adaptive to the state of its higher transpiration rate, lower content of relative water and bigger water saturation deficit. one - layer shading enhances the contents of iaa, ga and zrs, which is consistent to its growth condition
自然光照條件下生長的曼地亞紅旱杉aba含量最高， iaa 、 zrs 、 ga含量較低，這與其蒸騰速率較大，植株含水量較低，水分飽和虧缺較大相適應；一層遮蔭提高了iaa 、 ga 、 zrs含量，這與其生長狀況相一致。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。
