嘉平大枣果实在发育过程中 ,单、双糖含量在各年间虽有差异 ,但均遵循各自的规律变化 ,与生长期及平均单果重有极显著和显著的相关性。其单糖与生长期呈极显著的正相关 ,拟合曲线为 3次多项式 ,3年均值回归方程Y =-0 .0 0 0 0 4X3+ 0 .0 0 86X2 - 0 .4883X + 12 .812R =0 .9985 (n =7)。单糖与平均单果重呈极显著的指数曲线正相关 ,3年均值回归方程Y =3.6 899e0 .0 855X R =0 .9937 (n =7)。果实的内双糖在果核完全硬化后才开始出现 (即头棚枣花后 70天 ,二棚枣花后 6 0天 ) ,到完熟期剧增。其含量与生长期和平均单果重分别呈极显著和显著的指数曲线正相关 ,3年均值的回归方程分别为Y =0 .0 0 0 2e0 .10 95X,Y =0 .0 0 18e0 .6338X,R =0 .992 3 (n =4)。
During the development of Jiaping jujube fruit, the content of mono and disaccharides varied in different years, but all had their own regular changes, which had extremely significant and significant correlation with growth period and average fruit weight. The monosaccharides and growth phase showed a significant positive correlation, the fitting curve for the third degree polynomial, 3-year average regression equation Y = -0.0004X3 +0.086X2-0.4883X12.88R = 0 .9985 (n = 7). The monosaccharide and average fruit weight showed a very significant exponential curve. The 3-year mean regression equation was Y = 3.6 899e0.0855X R = 0.9937 (n = 7). The fruit’s internal disaccharides only begin to appear after the nucleus is completely hardened (ie, 70 days after the first ceiling date and 60 days after the second roof date), and then sharply increase to the maturity stage. The content and the growth period and the average weight of fruit were significantly and significantly exponential curve was significantly correlated, the regression equation of 3-year mean were Y = 0.00002e0.1095X, Y = 0.018e0.6338X , R = 0.992 3 (n = 4).
