摘　　要：以西葫芦杂交种"硕丰"为试材,研究了银叶粉虱(Bemisia argentifolii)对西葫芦(Cucurbita pepo L.)果实品质的影响。结果表明:银叶粉虱使西葫芦果实叶绿素a、叶绿素b、类胡萝卜素含量及叶绿素总量降低;可溶性糖、可溶性蛋白、游离氨基酸及维生素C含量也降低。在健康植株的果实中检测到醇类、酯类、烃类、杂环类、醚类、醛类等31种芳香物质,而在银叶病株的果实中只检测到20种,二者共有7种芳香物质。银叶粉虱引致的西葫芦银叶病可使果实褪绿,营养品质和风味品质降低。Taking the Culurbita pepo L. hybrid ＇Shuofeng＇ as material, the effect of Bemisia argentifolii caused by Bernisia argentifolii infestation on the fruit quality of Culurbita pepo L. were studied. The results showed that silver leaf whitefly decreased chlorophyll a, chlorophyll b, carotenoid and total chlorophyll content the contents of soluble sugar,soluble protein,free amino acids and Vitamin C in fruit from infested plants were much lower than that one from healthy plants. The main aromatic substances detected in fruit were alcohols, esters, alkanes, heterocyclies, ethers, aldehydes and some few other components. Among them, 20 substances found in fruit from infested plants and 31 substances found in fruit from healthy ones. They both had 7 substances. Fruit from infested plants decreased Chlorophyll, nutritive value and flavor.
