Copper is toxic to sensitive species of terrestrial vegetation at >40 pg/L nutrient solution (seedlings of pines, Pirns spp.), at >10 mg/kg DW leaves (cucumber, Cucumis sativus), and >60 mg extractable Cu/kg DW soil (sweet orange, Citrus sinensis Table 3.4). Among sensitive species of terrestrial invertebrates, adverse effects on survival, growth, or reproduction occur at 2 pg Cu/cm2 on paper discs (earthworms), >50 mg Cu/kg diet (larvae of gypsy moth, Lymantria dispar), and 53 to 70 mg Cu/kg DW soil (earthworms and soil nematodes Table 3.4). 

Growth of Seedlings. Cucumber (Cucumis sativus L., cv. Wisconsin SMR-IS) and soybean (Glycine max L. Merr., cv. Wayne) were grown in vermiculite and watered daily in a controlled environment chamber (26 2 C day, 21 2 C night) on a 12 hr photoperiod (eight 30-W cool-white fluorescent tubes plus four 25-W incandescent bulbs 200+foot-candles). The balanced nutrient solution of Frick and Mohr (H9), modified to include 1 g/1 Ca(N03)2 but without sucrose, succinic acid and kinetin, was applied on alternate days.

Cucurbitacin is a bitter-tasting principle that can be isolated from members of the family Cucurbitaceae, such as cucumber Cucumis sativus) and melon (Cucumis melo L.). In particular, cucurbitacin149 and momordicine,150 which have an intensely bitter taste, are contained abundantly in Momordica charantia (bitter melon in English, go-yaa in Okinawa, Japan), which people enjoy due to its bitterness. There are more than 18 kinds of cucurbitacin, and among them cucurbitacin B is a typical component. It has been reported that cucurbitacin exhibits anticancer activity.1 1 In addition, it is used for the treatment of hepatic disease in traditional Chinese medicine. It is also found in some herbal teas.

Ascorbate oxidase is found in higher plants, but cucumber, Cucumis sativus, and green zucchini squash, Cucurbita pepo medullosa, are the most common sources (29). The immunohistochemical localization of ascorbate oxidase in green zucchini reveals that ascorbate oxidase is distributed ubiquitously over vegetative and reproductive organs in all specimens examined (50). Primary structures of ascorbate oxidase from cucumber, C. sativus (51), pumpkin, Cucurbita sp. Ebisu Nankin (52), and zucchini, C.pepo medullosa (53), have recently been reported. 

These results clearly showed the relative significance of different routes of exposure, and the varying degrees of mobility after uptake. This is consistent with results for the uptake of polychlorinated dibenzo[l,4]dioxins and dibenzofurans from soils. In zucchini and pumpkin belonging to the genus Cucurbita, root uptake was dominant, whereas for cucumber (Cucumis sati-vus) foliar uptake was the primary mode and was much lower (Hulster et al. 1994).
