| 摘 要： | 对桂热1号火龙果结果母枝性状、果实性状及其相关性进行了调查分析。结果表明：枝条长度与棱厚、茎围显著或极显著负相关,与茎段数显著正相关；茎围与棱厚显著正相关。母枝性状中,枝条的棱厚和果实性状相关性最为密切,与单果重、果实纵径、果形指数间均存在显著正相关性。枝条的茎围与边糖之间显著负相关,但与心糖之间相关性不显著。火龙果果实多项性状指标间同样存在显著相关性,单果重、果实横径、果实纵径和果皮厚度四个指标两两间显著或极显著正相关性。果形指数与单果重、果实纵径呈极显著正相关；心糖和边糖显著正相关；果皮厚度和心糖间显著负相关。92.4%结果母枝的棱厚在14mm以上,单果重随棱厚的增加而增加。此研究结果可为火龙果栽培管理提供参考。

Correlation Between Bearing Shoot Characters and Fruit Traits of Pitaya |
| |
| Abstract: | The characters of bearing branch and fruit in Gui Re No. 1 pitaya as well as the correlation between them were investigated and analyzed. The results showed that the bearing shoot length was significantly or very significantly negatively correlated with the arris thickness and stem circumference, but significantly positively correlated with the number of stem segments. Stem circumference is positively correlated with arris thickness. Among bearing branch characters, arris thickness was most relevant to the fruit traits. It was positively correlated with the fruit weight, fruit longitudinal diameter and the fruit shape index. Stem circumference has a significant negative correlation with the soluble solid content of the pulp near pericarp, but no significant correlation with the soluble solid content of the central pulp. Significant correlation was also among multiple indicators of fruit traits. There was significant or very significant positive correlation between any two of fruit weight, fruit longitudinal diameter, transverse diameter and pericarp thickness. Fruit shape index was positively correlated with fruit weight and longitudinal diameter. There was significant positive correlation between the soluble solid content of the pulp in central and near pericarp. And a significant negative correlation between pericarp thickness and soluble solid content of central pulp. The arris thickness of 92.4% bearing shoot of was more than 14mm, which the fruit weight was increased with. These results can provide reference for the cultivated management of pitaya. |
