不同栽培基质对西甜瓜果实品质的影响

Effects of Different Substrates on Fruit Quality of Watermelon and Melon

以泥炭和椰糠为栽培基质,研究了西甜瓜果实的品质差异。结果表明:泥炭栽培中西甜瓜的外观品质更优,但是椰糠栽培中果实的心糖和蔗糖含量高,且酯类物质(甜瓜果实的特征香气)含量高,而醛类物质(西瓜果实的特征香气)含量则在泥炭栽培中更高。说明采用椰糠栽培可在一定程度上提高西甜瓜的果实品质。

Taking peat and coir as matrix ,effects of different substrates on fruit quality of watermelon and melon were studied. The results indicated that the appearance of watermelon and melon were better in peat, while the centre total soluble solid and sucrose contents of fruits in coir were higher. Moreover,relative contents of esters （characteristic aroma compounds of melon） and aldehydes （characteristic aroma compounds of watermelon） were higher in coir and in peat, respectively. In all,coir was a kind of cultivation substrate to improve the fruit qualities of watermelon and melon.
