摘　　要：以南瓜自交系494、277与黄瓜自交系1184、1101为砧木,以黄瓜1184、1101为接穗,研究比较了南瓜/黄瓜、黄瓜/黄瓜6种砧穗组合下嫁接黄瓜果皮、果肉与叶片等部位的硅含量以及果面明度差变化。结果表明:砧木277嫁接2种黄瓜接穗各部位的硅含量显著降低,其中多蜡粉接穗(1184)的果面明度差显著低于自根对照(1184),少蜡粉接穗(1101)的果面明度差与自根对照(1101)无差异;砧木494嫁接2种黄瓜接穗各部位硅含量无明显增加,其中多蜡粉接穗(1184)的果面明度差增加不显著,少蜡粉接穗(1101)的果面明度差相比自根对照(1101)显著增加;开花后5d与10d的果肉硅含量相对开花当天的有显著增加,果皮硅含量在不同时期变化不显著;果面蜡粉差异显著的2份黄瓜接穗果皮与果肉硅含量差异不显著。Using two pumpkin inbred lines（494and 277）,and two cucumber inbred lines（1184and 1101）as rootstocks,cucumber inbred lines（1184and 1101）as scions,own-rooted cucumber as control,silicon contents in peel,pulp and leaves and fruit surface lightness difference were examined in six rootstocks/scions combinations（pumpkin/cucumber,cucumber/cucumber）.The results showed that the silicon contents of two cucumber scions grafted by rootstock 277 were reduced significantly,and the fruit surface lightness difference of grafted combination 277/1184 were significantly lower than that of own-rooted 1184 plants,and the fruit surface lightness differences between combination 277/1101 and own-rooted1101 plants were undifferentiated.The silicon contents of two cucumber scions grafted by rootstock 494 were increased insignificantly,and the fruit surface lightness difference between grafted combination 494/1184 and own-rooted 1184 control were increased insignificantly,and the fruit surface lightness difference of grafted combination 494/1101 was significantly increased than that of own-rooted 1101 control.The lightness difference of grafted combination 494/1101 was increased significantly as compared with that of the grafted combination 277/1101 and the own-rooted control 1101,but the silicon contents in grafted cucumber 494/1101 were not significantly different from the own-rooted 1101 plants.
