    結果表明： （ 1 ）中間錦雞兒、小葉錦雞兒和樹錦雞兒的植物學性狀和生物學特性具有差異，如莖干有毛或光滑、樹的高矮、抗性的強弱等；也有一定的相似性，如有小葉、托葉在長枝上宿存可硬化成針刺等。
  2. Pre - differentiation and proper partial desiccation of calli before transferred to regeneration medium was found to apparently improve the frequency and quality of plant differentiation. with our optimized culture condition and treatment style, induction frequency of pei ' ai64s and 9311 can be reached 62. 45 % and 85. 30 % respectively and after 3 months of subculture calli can remain high - quality embryogenic state, when high - quality embryogenic calli after two times of subculture were used as acceptor, callus differentiation frequency can arrive at 85. 5 % and 87. 7 % respectively

    採用我們優化后的培養條件與處理方式，培矮64s和9311愈傷組織的誘導頻率分別可達到62 . 45和85 . 30 ；繼代培養時間達三個月左右仍能保持較好的胚性生長狀態；對于繼代兩次胚性生長狀態良好的愈傷組織分化頻率分別可達到85 . 5和87 . 7 。
  3. For parameter a, there is a close relationship exist between a ( 9, sr ) in two different radar incident angle that can be expressed as : with considering the effects of soil texture, we get the final expression of the inversion model : where mv ( t1 ), mv ( t2 ) is volumetric soil moisture content in two different temp, c, d is soil type related parameters, and v ( t1 ), s ( t2 ) is coresponding bare soil radar backscattering coefficients. inversion results show that for the c band hh polarized radarsat scansar data with a range of incidence angle from 20 to 40, the soil moisture change value can be derived with an acceptable accuracy using the above model. the temporal and spatial soil moisture change patterns are associated with rainfall and vegetation cover, as well as the soil hydraulic characteristics

  4. The future characterization and genetic analysis for candidate mutant were carried out and find that some candidate mutant ( such as roi30 doil - 1 doi0311131 ) have good phenotype by drought h2o2 aba - stressed treatment. at the same time we also observe the development of candidate mutant at different growth stages carefully. many modal difference between mutant an d wild type at the same period were found, such as more rosette layering fatty and big in leaves, advancment or delay for the flower period, rosettes living in the main stem, shorten in figure, the amount of seed little, sterilization etc. these physiological and modal changes may reflect with maladjustment in expressions of some gene and confusion on their inner control, . we will futher study concrete and detailed function mechanism

    我們對這些擬南芥侯選突變體進行進一步的鑒定和遺傳學分析，發現ro口口、 doil 、 doi口jlll3i等潛在突變株對aba 、過氧化氫及早脅迫有明顯表型，同時對潛在突變體的生長發育進行了詳細的觀察，發現多數潛在突變株與同條件下野生型比出現了許多明顯的形態改變，如:蓮座基葉增多、分層、肥大，花期提前或延遲，主莖生輪座，株型矮化，產籽量少，不育，敗育等，這些生理和形態上的差異很可能反映了它們內部某些基因的表達受到了影響、代謝調控發生了紊亂，具體和詳細的作用機制還需要進一步的研究。
