摘　　要：【目的】研究结果枝对火龙果果实品质的影响,为火龙果优质栽培提供科学依据。【方法】以桂红龙1号火龙果为试材,研究结果枝对果实单果质量、横径、纵径、果形指数、果皮厚度、心糖含量和边糖含量的影响。【结果】结果枝性状中只有茎围与棱厚呈极显著正相关(P<0.01)。果实品质有多项指标间存在显著(P<0.05)或极显著(P<0.01)的相关性。结果枝茎围与果实横径、心糖含量均表现为显著正相关(P<0.05),结果枝棱厚与单果质量、果实纵径、果皮厚度均显著正相关(P<0.05),结果枝长度与心糖含量显著正相关(P<0.05),结果枝生长角度与果皮厚度显著正相关(P<0.05),结果枝段数与果实品质各指标间的相关性均不显著(P>0.05)。棱厚≥18.00 mm的结果枝单果质量、果实横径和纵径都显著大于棱厚<14.00 mm的结果枝(P<0.05)。朝南枝条果实的单果质量和横径均显著大于朝北枝条(P<0.05);朝东枝条果实的果皮厚度显著小于朝西和朝北枝条(P<0.05);果实的纵径、果形指数、心糖含量和边糖含量在各朝向枝条间均无显著差异(P>0.05)。【结论】培养茎围大、棱厚度大、生长角度小的长结果枝有利于收获果型大、甜度高、果皮薄的火龙果。[Purpose]The influence of bearing branch on the fruit quality of pitaya(Hylocereus undulates Britt.)was studied in order to provide scientific basis for the high-quality cultivation of pitaya.[Method]‘Guihonglong No.1’pitaya was used as material to study the effects of bearing branch on the single fruit weight,transverse diameter,longitudinal diameter,fruit shape index,peel thickness,the soluble solid content of central flesh and the soluble solid content of marginal flesh.[Result]Only stem circumference and arris thickness were in a highly significant positive correlation among bearing branch characters(P<0.01).There were many indexes of fruit quality having a highly significant(P<0.01)or significant correlation(P<0.05)with each other.The stem circumference of bearing branch showed significantly positive correlations with the transverse diameter of fruit and the soluble solid content of central flesh respectively(P<0.05),the arris thickness of bearing branch showed significantly positive correlations with single fruit weight,the longitudinal diameter of fruit and peel thickness respectively(P<0.05),there was a significantly positive correlation between the length of bearing branch and the soluble solid content of central flesh(P<0.05),there was a significantly positive correlation between the growth angle of bearing branch and peel thickness(P<0.05),none of the correlations between the segment number of bearing branch and each index of fruit quality were significant(P>0.05).The single fruit weight,transverse diameter and longitudinal diameter of fruits from the bearing branches with arris thickness 18.00 mm were all significantly larger than those with arris thickness<14.00 mm(P>0.05);the single fruit weight and transverse diameter of fruits from southward branches were all significantly larger than those from northward branches(P<0.05),the peel thickness of fruits from eastward branches was significantly smaller than those from westward branches and northward branches respectively(P<0.05),there were no sign
