Abstract:

【Objective】To study the effects of nitrogen application on the flavor quality of melon at maturity stage in the hope of enhancing technical measures to improve its flavor quality.【Methods】The melon variety Huang Mengcui melon fruits were taken as the test material to study of nitrogen transport effects under different nitrogen fertilizations: N0 (Nitrogen deficiency), N1(Low nitrogen), N2(Medium nitrogen), N3(High nitrogen),CK(no fertilization)and M(Organic fertilizer)on the aromatic compounds and nutritional quality of the fruit in Sanya.【Results】In terms of the types of aromatic substances, a total of 346 aromatic substances were detected in the six treatments, of which 25 were commonly found, mainly alcohols, aldehydes, and esters. The total and unique types of aromatic substances under low nitrogen treatment are the highest, with 167 and 12 species, respectively. Aromatic substances that appear with increasing nitrogen levels include ethyl butyrate, ethyl propionate, ethyl 2-methylbutyrate, 2-Butyn-1-one, 1-cyclohexyl-4,4-diethoxy -, (E) - non 6-en 1-ol, etc; the highest ester content in high nitrogen treatment was 12.28%, while the lowest ester content in nitrogen deficiency treatment was 4.81%. The characteristic aromatic substance ethyl acetate showed an increasing trend with the increase of nitrogen application rate, while the increase of methyl acetate nitrogen application rate showed a trend of first increasing and then decreasing; the highest soluble solid content in the high nitrogen treatment center was 15.40%, while the lowest soluble solid content in the M treatment center was 13.40%. The maximum weight of a single melon under medium nitrogen treatment is 1.95 kg, and the minimum CK is 1.74 kg.【Conclusion】Under the condition of different nitrogen levels, the composition and content of aromatic substances in melon changed, resulting in the difference in the content of common aromatic substances and the existence of unique characteristic components. N1 treatment was beneficial to increase the type and relative content of aromatic substances; N2 and N3 treatments increased single fruit weight and content of soluble solids, respectively.

摘要:

【目的】研究氮素运筹对甜瓜果实芳香物质变化的影响,为提高甜瓜风味品质的技术措施提供依据。【方法】以甜瓜品种黄梦脆为试材,在设施栽培条件下研究氮素运筹6个处理(N0:缺氮;N1:低氮;N2:中氮;N3:高氮;CK:不施肥;M:有机肥)对甜瓜芳香物质变化规律。【结果】6个处理共检出346种芳香物质,其中共有的芳香物质为 25种,主要为醇类、醛类和酯类。低氮处理芳香物质总种类及特有种类最多,分别有167和12种。随着氮素水平增加而出现的芳香物质有:丁酸乙酯、丙酸乙酯、2-甲基丁酸乙酯、2-Butyn-1-one, 1-cyclohexyl-4,4-diethoxy-、(E)-non-6-en-1-ol等;高氮处理酯类含量最高为12.28%,缺氮处理酯类最低为4.81%。特征芳香物质乙酸乙酯随着施氮量的增加有增加趋势,乙酸甲酯施氮量的增加有先升后降的趋势;高氮处理中心可溶性固形物含量最高为15.40%,M处理中心可溶性固形物含量最低为13.40%。中氮处理单瓜重最高为1.95 kg,CK最低为1.74 kg。【结论】不同氮素水平条件下会引起甜瓜芳香物质的成分、含量的变化,导致共有芳香物质种类含量的差异以及特有特征成分的存在;低氮处理有利于丰富甜瓜芳香物质的种类和提高甜瓜特征芳香物质乙酸丁酯、乙酸己酯的相对含量;中氮、高氮处理分别提高单果重和中心可溶性固形物含量。
