Comparison analysis of two glossiness fruit shape characteristics of Ziziphus jujuba Mill.cv. 'Lingwuchangzao'
[Objective]To explore the differences between the glossiness and appearance characteristics of two kinds of glossy fruits of'Lingwuchangzao'including high glossy fruits(S fruits)and low glossy fruits(R fruits),so as to provide reference and guidance for the high-quality and high-efficiency cultivation of'Lingwuchangzao'.[Method]The two kinds of glossy fruits(S/R fruits)of'Lingwuchangzao'of 6 years old,9 years old and 12 years old were collected as experimental materials,and the fruit appearance characteristics such as glossiness,single fruit mass,transverse and longitudinal diameter of fruit,hardness of fruit,skin thickness,flesh thickness,longitudinal and transverse diameters of kernel,single kernel mass,edible rate and kernel rate were determined,and the comparison and correlation analysis of these traits were tested.[Result]1)The single fruit mass,fruit transverse and longitudinal diameter,fruit skin thickness,nuclear longitudinal and transverse diameter,and kernel content of R fruit of three tree ages were all extremely significantly greater than those of S fruit(P<0.01),of which the kernel content of R fruit at 6,9 and 12 years of age was 28.04,15.49 and 14.99 times greater than that of S fruit,respectively,and the glossiness of R fruit was extremely significantly less than that of S fruit(P<0.01),and only 63.1%-67.1%of S fruit,flesh thickness of R fruit and single kernel mass were significantly greater than those of S fruit(P<0.05);12 years old R fruit edible rate was the smallest,and 9,12 years old were significantly smaller than the same year of S fruit edible rate;2)Different tree ages'Lingwuchangzao'of the high-gloss fruits(S fruit):in the glossiness,single fruit mass,the fruit longitudinal and transverse diameter,the hardness of the fruit,fruit flesh thickness,longitudinal diameter of the kernel,single kernel mass,edible rate was a significant difference(P<0.05)in the age of the tree;in the low gloss fruit(R fruit):its longitudinal diameter of the fruit,fruit hardness,fruit skin thickness,longitudinal and transverse diameter of the kernel,single kernel mass,edible rate of the fruit was a significant difference(P<0.05),and with the S fruit performance were not the same;(3)Different tree age plants'Lingwuchangzao'S/R fruit glossiness were related to the individual fruit mass,fruit longitudinal diameter was highly significant positive correlation;S fruit of the age of the tree and the mass of an individual fruit,fruit transverse longitudinal diameter,pulp thickness,longitudinal diameter of the jujube seed,the mass of an individual seed,edible rate of significant or highly significant negative correlation;R fruit of the age of the tree and the longitudinal diameter of the fruit,edible rate of significant or highly significant negative correlation with the hardness of the fruit,fruit skin thickness,the core of the transverse diameter of the core,the mass of a single core was significant or highly significant positive correlation.[Conclusion]Two glossy fruit gloss and appearance characteristics of different'Lingwuchangzao'tree ages are highly significant differences(P<0.01),and there is a significant correlation(P<0.05)between the ages of the tree,glossiness and other appearance characteristics.
