  4. Leaf water potential of populus euphratica and influencinge factors in extreme arid region

    極端乾旱區胡楊水勢及影響因子研究
  5. Length, diameter, density, fresh weight, dry weight, water content, osmotic potential and element concentrations ( ca, mg, na, k, cl ) were determined for each. seedling of b. gymnorrhiza and a. corniculatum were cultured for 60 days on various salinity of seawater ( 0, 5, 10, 15, 20, 30, 40, 50 ) in green house. samples were taken at 3, 7, 11, 15, 22, 30, 45 and 60 days after planting, separated into root, hypocotyl, stem and leaf

    本文研究了福建九龍江口木欖和桐花樹胎生繁殖體從果實形成到發育成熟過程中形態、生物量、含水量、胚軸密度、滲透勢、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化和溫室內人工鹽度梯度栽培下木欖和桐花樹成熟繁殖體長成幼苗（ 0 60d ）過程中形態、生物量、含水量、滲透勢、光合蒸騰特性、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化；並且在野外自然條件下，跟蹤調查不同灘塗位置下秋茄成熟繁殖體定居成活、自然死亡狀況以及測定幼苗生長過程中（ 1年）形態、生物量、含水量、光合蒸騰特性等的變化。
  6. ( 5 ) varying trend of leaf water potential differs in different seasons. leaf water potential changes significantly with temperature. the speed of leaf water potential rising with temperature in heavy saline is faster than that of in light saline

    （ 5 ）油葵葉水勢各生育階段變化趨勢不同，隨溫度變化顯著，多數階段葉水勢都隨溫度升降呈現相同變化，含鹽高的小區葉水勢升降速度高於低含鹽區葉水勢低於低含鹽區，可以反映土壤水分脅迫和鹽分脅迫。
  7. The results showed that the transpiration rate 、 leaf rwc 、 water potential, water - consumption and water use coefficient were decreased with soil water decreasing

    結果表明，蒸騰速率、葉水勢、葉片相對含水率、耗水量和耗水系數均隨十壤水分的減少而呈降低趨勢。
  8. The changes of leaf water potential, water deficiency, water - holding ability under drought stress conditions were measured. the water parameters were calculated by using pressure - volume technique, also the abilities of maintaining turgor and adjusting osmotic potential of the four species were comprehensively evaluated. the effects of drought stress on photosynthesis, transpiration and water use efficiency were studied

    研究乾旱脅迫下葉水勢、葉水分飽和虧缺及葉保水力的變化；應用壓力室和pv技術測定四個樹種多項水分參數，並對四樹種滲透調節和維持膨壓能力進行綜合評定；研究乾旱脅迫對光合作用、蒸騰作用及水分利用效率的影響；測定生長指標及水分脅迫下苗木的生物量分配。
