  1. The study investigated aboveground growths of caragana korshinskii and artemisia ordosica planted in four modes, revealing that in different planting modes their densities, heights and canopy width and biomasses remained unchanged or tended to decrease slightly ; the young shoots of a. ordosica annually grew in a s - shaped cure and the young shoots of c. korshinskii grew fast in spring and grew slowly or cease to grow from july on ; the biomasses and leaf area indexes of c. korshinskii and a. ordosica annually varied in a double peak curve and there were 8 annual plants that invaded in the four planting modes and formed higher coverage ; the quadrat with only a. ordoska appeared to have obviously lower coverage and biomass that the other three quadrats

    摘要對騰格里沙漠東南緣2種人工植被檸條和油篙在4種配置方式下地上部分的生長動態進行了研究,結果表明:不同配置方式下它們的密度、高度、冠幅和生物量基本不變或略微呈下降趨勢;油篙新梢的年生長動態呈s型曲線,檸條新梢春季生長速度較快, 7月份以後生長速度緩慢或基本停止生長;檸條、油篙地上生物量和葉面積指數的年變化均表現為雙峰型, 4種配置方式下共有8種1年生植物人侵,並具有較高的植被蓋度;同其它3個樣地相比,純油篙樣地1年生植物的密度、蓋度和生物量明顯偏低。
  2. Plants growing in the semi - fixed sand dunes, on the other hand, were less branchy with a larger number of first - year shoots which were longer, and grew faster ; their leaves were longer and wider with a low length / width ratio. the characteristics of the branching system and leaf dimensions of the plants in fixed sand dunes were rather intermediary between those of the above. the frequency distribution and their frequency in the herb layer the scrubs also varied with habitats

    丘間低地的黃柳灌叢當年枝平均長度增加緩慢,短枝條的比例較高,當年枝枝長頻度分佈峰值偏左,葉片短而狹,長寬比大;與之相比,分佈於半固定沙丘的灌叢當年枝平均長度增加較快,長枝條比例較高,葉片長而寬,長寬比小;固定沙丘上的上述特徵大致介於二者之間。
  3. Here we found g proteins also function in leaf, silique development and the yield of pollen microspore. we observed several traits or characters in the offsprings of gpal, agbl null mutation and gpa1 overexpression lines and found that the width of mutants " lamina is larger than that of the wild type, whereas the lamina length, petiole length and rosette diameter is smaller than the wild type, the ga overexpression lines is different from the mutants ; the silique length and the pedicel length is larger in mutants than that of wild type, and slightly smaller in overexpression lines than the control ; the morphometric character in silique tip is different in gpal from agbl mutants ; the yield of pollen microspore is larger in null mutants than wild type whereas smaller in overexpression lines

    實驗中我們跟蹤觀察了多代異三聚體g蛋白a亞基超表達轉基因植株及a , p亞基缺失突變體的表型特徵,發現突變體的葉片寬度大於對應的野生型,葉片長度,葉柄長度及蓮座直徑小於野生型,而超表達植株的上述某些特徵與突變體相反; gp時突變體的長角果長度,花梗柄部長度大於野生型,而超表達ga植株種英則略小於對照; gpal突變體長角果尖端未出現咭乙i突變體的特徵: gpal ,口gbl突變體花粉生成量大於野生型,而超表達ga植株的花粉生成量則略小於對照。
  4. The most significant variance lay in the 1000 - seed - weight, followed by flag leaf length and inflorescence shape and then by distance between flag leaf and inflorescence with least in inflorescence length, plant form, leaf width and seed length

    其中,種子千粒重變異最大;旗葉長度、花序形狀次之;穗葉距、花藥寬度、旗葉寬度等性狀變異中等;而花序長度、株型、葉寬、種子長度變異最小。
  5. The leaf area estimations were found to be significantly correlated to the parameters ( leaf length, leaf width, leaf fresh weight and leaf dry weight ) measured, and be applicable in nondestructive experiment by using leaf length or width

    這為蘿卜葉面積的測定提供了一個簡單實用的測定方法,特別是通過葉長、葉寬與葉面積的回歸方程可不破壞植株從而測出田間蘿卜植株的葉面積。
