  • Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

    Creator:
    Wang, Yueju
    Abstract:
    The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

  • Factors affecting the incidence and severity of Phytophthora syringae cankers in pear (Pyrus communis) trees

    Creator:
    Laywisadkul, Srisangwan
    Abstract:
    Container grown pear trees were used to determine the effects of the following factors on the susceptibility to Phytophthora syringae: 1) tree nitrogen (N) status and foliar sprays of urea and copper-EDTA (CuEDTA); 2) dormancy and environmental conditions; 3) wound and wound age; and 4) chemical and biological control measures....

  • Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

    Creator:
    Ding, Pinghai
    Abstract:
    Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...
