摘　　要：以新疆产不同抗裂性枣品种‘骏枣’、‘哈密大枣’、‘灰枣’、‘金铃圆枣’果实为试验材料,用不同浓度CaCl2(0、2.5、25g/L)分别浸泡12、36、60h,研究CaCl2对枣裂果率及果肉、果皮中Ca、K、Mg含量的影响。结果显示:(1)2.5、25g/L CaCl2均能有效降低枣裂果率,且25g/L CaCl2对各品种枣的防裂效果均优于2.5g/L CaCl2。(2)极抗裂品种枣的果皮、果肉中Ca显著高于极易裂品种,且各品种Ca含量均随CaCl2浓度增加而增加。(3)极抗裂品种枣的果皮、果肉中K含量高于极易裂品种,其Mg含量则表现出相反趋势,但不同浓度CaCl2处理的枣果肉、果皮中Mg、K升降幅度变化不同。(4)枣果肉、果皮中Ca、K含量与裂果率呈负相关关系,Mg含量与裂果率呈正相关关系。研究认为,CaCl2浸果能有效增加枣果肉、果皮中钙含量,影响各品种枣果实的钾镁含量,显著降低枣裂果率,并以25g/L CaCl2效果最好。＇ J unzao＇ ,＇ Huizao＇, ＇ Haomidazao ＇ and ＇ Jinlingyuanzao＇ which produced in Xinjiang were used as materials. They were immersed by different concentrations of CaCle （0,2.5,25 g/L） at three stages（12,36, 60 h） to study effects of CaCI2 on,jujube cracking rate and Ca,K and Mg contents of fruit pulp and peel. The result indicated that：（1）Both 25 and 2.5 g/L CaClz can effectively reduce the jujube fruit cracking rate,and the former was superior than the latter. （2）The Ca content of fruit pulp and peel in the highest crack resistance cultivar was higher than that in the lowest crack resistance. With increasing of CaC12 con- centration,the Ca content was also increased. （3）The K content of fruit pulp and peel in the highest crack resistance jujube was higher than that in the lowest crack resistance. On the contrary,the Mg content o{ fruit pulp and peel in the highest crack resistance jujube was lower than that in the lowest crack resistance, but the K and Mg contents of fruit pulp and peel showed different change with different concentrations of CaC12. （4）The contents of Ca and K in fruit pulp and peel were negative correlated with fruit cracking rate. The Mg content of fruit pulp and peel were positive correlated with fruit cracking rate. The study showed that the jujube fruit soaked by CaC12 reduced fruit cracking rate,increased Ca content of fruit pulp and peel,and impacted K and Mg contents of jujube.
