以30年生‘石硖’龙眼为试材,应用生物统计软件对结果母枝单元质量的6个变量和果穗性状的4个变量,与果实外观色泽和单果重、可溶性固形物含量及落果率进行相关分析,结果表明:母枝单元质量与挂树期果实外观色泽关系均未达显著水平,而母枝直径与单果重为显著多项式相关关系,与果实可溶性固形物含量为显著正单相关关系;果穗宽度、果穗体积分别与可溶性固形物含量有显著、极显著正单相关关系,果穗长度与果皮L*为显著多项式相关,果穗长度和果穗体积分别与落果率有极显著多项式相关;复叶数、小叶数、小叶面积和总叶面积均与挂树龙眼保鲜效应无关。建议根据结果母枝质量分批次先后采收,将母枝单元直径0.87cm左右,果穗体积适中(V≈1 124.03cm~3),长度在36.67cm左右,叶色浓绿有光泽的果穗进行挂树延后采收。
Using the 30-year-old ’Shijie’ longan as test material, four variables of fruit quality and 6 characters of ear fruit were compared with fruit appearance color and fruit weight, soluble solids content and fruit drop rate The results showed that there was no significant correlation between the quality of female branches and the appearance color of the fruits at the time of hanging, while the diameter of parent branches and the weight of single fruit were significant polynomial correlations, which had a significant positive correlation with soluble solids content. There were significant and very significant positive correlations between fruit width and ear volume and soluble solid content, respectively. Ear length was related to L * of peel, significant polynomial, fruit length and fruit size respectively. , Number of leaflets, leaflet area and total leaf area all had nothing to do with the preservation effect of hanging longan. According to the results of the quality of the mother plant has been collected in batches, the mother unit diameter of about 0.87cm, the ear volume is moderate (V ≈ 1 124.03cm ~ 3), the length of 36.67cm or so, leaf color dark green shiny ear Hanging tree delayed harvesting.
