In the north of China, it is quite easy to purchase the season fruit from Southeast Asia, such as Pitaya fruit from Thailand, pawpaw from Malaysia and bananas from Philippine.

It took about 27-30 days from blossom to ripen for pitaya fruit, fruit weight has 2 growth peaks during growth development period. The fresh and dry weight development of pitaya fruits presented doubles S curve.

火龙果果实从开花到成熟需27～30d，果实的单果重在生长发育期有两次增长高峰；果实鲜重、干重生长型均为双S曲线型。

Potassium content in pitaya fruit squama and flesh were at a fairly high level 3 days after flowering, and then intended to drop, potassium content in fruit pericarp was highest during fruit mature stage.

火龙果花后3d鳞片和果肉钾含量维持较高水平，之后呈下降趋势，果皮钾含量在果实成熟时最高。

Pitaya fruit contains more mineral nutrients, particularly potassium, phosphorus, magnesium, calcium-rich contents are rich. Mineral nutrients content of pitaya produced in Luodian conty located in Guizhou karst mountain area is higher than pitaya from Conghua, Guangdong. 6.

火龙果含有较多的矿质营养元素，特别是钾、磷、镁、钙的含量丰富；产于贵州喀斯特山区罗甸的火龙果矿质元素含量高于广东从化的火龙果。

Pericarp changed from green to light red, finally to faint red or mauve, soluble solids increased rapidly, acidity increased first and then decreased and water content increased when pitaya fruit became mature. 3.

火龙果在成熟期时，果皮由绿转至浅红，最后转至淡红或紫红色；可溶性固形物迅速增高，酸度升高后下降；水分含量增加。

At present, the study of pitaya quality and physiological system are not many in China and abroad, especially, the study of pitaya fruit development and quality analysis have not been involved in the karst mountain area under specific ecological condition.

目前，国内外对火龙果品质生理系统研究不多，特别是在喀斯特山区特定的生态条件下火龙果果实发育规律及果实品质分析还未涉及。
