为研究不同钙制剂在骏枣不同生长发育时期施用后,对骏枣裂果、果皮、果肉中矿质元素和表皮结构的影响,以骏枣为供试材料,选用EDTA-Ca溶液、氯化钙(CaCl2)溶液对骏枣进行喷施处理.研究结果表明1)喷钙处理可有效降低骏枣裂果率,且喷EDTA-Ca溶液效果优于喷CaCl2溶液;2)喷钙处理可明显提高骏枣果实中Ca、K、P、Fe、Zn、B等矿质元素含量,在骏枣白熟期喷EDTA-Ca溶液对枣果实中矿质元素含量提升效果最佳;3)喷钙后表皮层、角质层、蜡质层厚度均增加,其中,喷EDTA-Ca溶液更有利于表皮层厚度的增加,喷CaCl2溶液更有利于角质层厚度的增加,相比之下,喷施EDTA-Ca溶液防裂效果更好.综上所述,喷施外源钙可降低骏枣裂果率,增加枣果实中矿质元素含量.
To study the effects of different calcium preparations on fruit cracking epidermal structure and the mineral elements in the peel,and pulp of fruit EDTA-Ca solution and calcium chloride(CaCl2)solution were sprayed on Junzao at different stages of growth and development.The results showed that 1)Calcium spraying treatment could effectively reduce the fruit cracking rate,and the effect of spraying EDTA-Ca solution was better than spraying CaCl2 solution.2)Calcium spraying treatment could significantly increase the content of mineral elements such as Ca,K,P,Fe,Zn and B in Jujube fruits,In addition,the treatment effect of spraying EDTA-Ca solution at the white ripening stage was the best.3)The thickness of the epidermis,stratum corneum,and wax layer increased after calcium spraying,among which,spraying EDTA-Ca solution was more conducive to the increase of epidermal thickness,spraying CaCl2 solution was more conducive to increasing the thickness of stratum corneum,compared with spraying EDTA-Ca solution had bet-ter anti-cracking effect.In summary,spraying exogenous calcium can reduce the fruit cracking rate and increase the content of mineral elements in the fruit.
