为探索甜瓜发育过程中生长模式、果实糖分积累与梯度分布的情况,在新疆维吾尔自治区葡萄瓜果研究所甜瓜基地进行小区试验,以甜瓜品种西州密25号为研究对象,测定其不同生长期果实纵横径、糖分积累的变化规律。结果表明:甜瓜果实纵、横径、单果质量都是单“S”型生长曲线,生长发育前期增长相对较慢,随后迅速生长,后期生长缓慢趋于平缓;果实发育早期葡萄糖、果糖迅速积累,蔗糖含量几乎检测不到,然而甜瓜网纹期至成熟期蔗糖迅速积累。果实成熟期检测的糖分梯度变化为蒂部果肉葡萄糖含量>蔗糖含量>果糖含量,脐部果肉与中部果肉蔗糖含量>葡萄糖含量>果糖含量。
In order to explore the growth pattern, fruit sugar accumulation and gradient distribution in the process of melon development, a plot experiment was conducted in melon base of Institute of Glucose and Fruit Research in Xinjiang Uygur Autonomous Region. The melon variety Xizhou25 was used as the research object to determine its growth period Changes in fruit length and breadth, sugar accumulation. The results showed that: the vertical, transverse diameter and single fruit quality of melon fruits were single “S” type growth curve, the growth was relatively slow growth, then grow rapidly, late growth tends to be slow; early fruit development of glucose, fructose rapidly Accumulation, sucrose content is almost undetectable, however, sweet melon reticulate period to maturity rapid accumulation of sucrose. The changes of the sugar gradient detected in the fruit ripening stage were the glucose content of sucrose, sucrose content, fructose content, sucrose content of umbilicus pulp and middle pulp> glucose content> fructose content.
