    Biological Characteristics of Border Cell of Tomato and Effect of Aluminum on Its Viability
    SUN Da-li, CUI Jie-chen, XU Gen-di, LIU Peng
    2006, 35(02): 1-4. 
    Abstract ( )   PDF (258KB) ( )  
    The biological characteristics of border cell of tomato (Lycopersicon esculentum) and the effect of aluminum on its viability were studied by aeroponic culture.The results showed that the first border cell almost occurred synchronously with primary root tip emergence and the numbers of border cells reached its maximum (893) when the root was 10mm long.The viability of border cell maintained over 93% and increased a little with the elongation of root.However,PME (Pectin Methylesterase) activities decreased slightly with the elongation of root.With the increase of concentration or time of aluminum treatment,viability of border cell decreased significantly.The results also indicated that aluminum was harmful to border cell of tomato.

    Cytohistological Study on Morphogenesis in filament Culture of Lilium‘Star Gazer’
    ZHOU Zu-fu, AI Su-yun, YANG Mei-chun, LI Zhao-an
    2006, 35(02): 5-8. 
    Abstract ( )   PDF (398KB) ( )  
    Segments from filament of Lilium ‘star gazer’ were cultured as explants on MS medium supplemented with BA 1.0 mg/L and NAA 0.2 mg/L to induce callus and organs.Cytohistological observations on callus and bud formation were carried out.The results were as follows.Callus was initiated from the cut surface of the morphological lower side of explants;Some callus packs developed into roots or shoots,and others developed into shoots from surface cells and developed into roots from inner cells.

    Study on Flowering Behavior and Meiosis of Pollen Mother Cells in Seedless Mango
    DONG Jun, LIN Dan-tong, LUAN Tian-gang
    2006, 35(02): 9-11. 
    Abstract ( )   PDF (178KB) ( )  
    Seedless Mango (Mangifera indica cv.Dongzhen Hongmang) was used to study its flowering behavior and meiosis of pollen mother cells with modified staining and chromosome preparing methods.The results were as follows.The chromosome number of mango is 40 and the meiosis in pollen mother cell is simultaneous cytokinesis;Monovalents is the optical period to study chromosome number;Polyploids are observed in monvovalents and cell's nonsynchronous division is observed in anaphase Ⅱ;Low temperature and rainy days probably gave an impulse to the polyploid and cell's nonsynchronous division;The relationship between abnormal circumstances in meiosis of pollen mother cells and seedless mango were studied on cytogenetics level.

    2006, 35(02): 12-16. 
    Abstract ( )   PDF (290KB) ( )  
    Navel orange (Citrus sinensis cvs.Robertson,Fengqi and Newhall) were chosen as testing materials in Zhoupo,Jingyan County.The studies of pectinmethylesterase (PE),polygalacturonase (PG),β-glycosidase and cellulase in navel orange during development of fruits were shown as follows.PE,PG and β-glycosidase could be tested at different stages.PE activity of pulp was greater than that of peel obviously,the changes of PE activities from Newhall and Robertson navel oranges had three peaks;PE activity of Newhall varied greatly than those of Robertson and Fengqi.PG activity was greater at maturity stage than at young and the expanding stages;PG activity in pulp was greater than in peel.β-glycosidase activity was tested firstly in fruits and the peak of β-glycosidase activity was at maturity stage.The peak of PE activity appeared earlier than those of PG and β-glycosidase.PE and PG were the major enzymes effected the development of navel orange fruits.

    Effects of Several Biological Factors on Anthocyanin Accumulation of Celosia cristata var.pyramidalis in Cell Suspension Culture
    ZHANG Jin-jie
    2006, 35(02): 17-20. 
    Abstract ( )   PDF (250KB) ( )  
    The effects of different concentrations of growth regulators and sucrose on anthocyanin production of Celosia cristata var.pyramidalis in cell suspension culture were studied.Anthocyanin accumulation treated with KT was significantly greater than that treated with 6-BA,and the maximal production of anthocyanin was obtained when treated with KT at 2 μmol/L.2,4-D 2 μmol/L and high concentration of sucrose could promote the accumulation of anthocyanin.MS+2,4-D 2 μmol/L+KT 2 μmol/L+sucrose 292 mmol/L gave the best result for anthocyanin accumulation.Light was essential for the induction of anthocyanin.The content of anthocyanin increased with the multiplication of suspension cells.
