为合理调控设施油桃钙素营养,改善设施油桃果实贮藏品质,延长设施油桃果品货架期,以贮藏期间的设施曙光油桃为试材,研究了不同施钙水平对油桃果实抗氧化酶活性及膜透性的影响。结果表明,与不施钙肥(对照)相比,土壤施钙显著增强了贮藏期间设施油桃果实抗氧化酶超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)的活性,三者均在贮藏后第10天达到峰值,分别为55.4U/g、5.27U/(g·min)、26.7U/g,其后随贮藏时间延长其活性呈下降趋势;随贮藏时间的延长,土壤施钙处理果实的相对质膜透性及丙二醛(MDA)含量呈上升趋势,至贮藏第30天达到最大值,分别为60%和6.17mg/g,整个贮藏期间土壤施钙处理果实质膜透性及MDA含量(P<0.05)低于对照。采前土壤施钙可显著提高贮藏期间设施油桃的SOD、POD、CAT活性,并显著降低设施油桃果实的质膜透性及过氧化产物MDA的积累。
為閤理調控設施油桃鈣素營養,改善設施油桃果實貯藏品質,延長設施油桃果品貨架期,以貯藏期間的設施曙光油桃為試材,研究瞭不同施鈣水平對油桃果實抗氧化酶活性及膜透性的影響。結果錶明,與不施鈣肥(對照)相比,土壤施鈣顯著增彊瞭貯藏期間設施油桃果實抗氧化酶超氧化物歧化酶(SOD)、過氧化物酶(POD)、過氧化氫酶(CAT)的活性,三者均在貯藏後第10天達到峰值,分彆為55.4U/g、5.27U/(g·min)、26.7U/g,其後隨貯藏時間延長其活性呈下降趨勢;隨貯藏時間的延長,土壤施鈣處理果實的相對質膜透性及丙二醛(MDA)含量呈上升趨勢,至貯藏第30天達到最大值,分彆為60%和6.17mg/g,整箇貯藏期間土壤施鈣處理果實質膜透性及MDA含量(P<0.05)低于對照。採前土壤施鈣可顯著提高貯藏期間設施油桃的SOD、POD、CAT活性,併顯著降低設施油桃果實的質膜透性及過氧化產物MDA的積纍。

T he effects of applying calcium in soil on fruit physiology characteristics of nectarine (Prunus persica var .nectarina cv .Shuguang) under protected culture during storage period ,so as to improve the the quality of the stored nectarine and prolong the storage time .The results showed that the application of calcium fertilizer in soil increased significantly the activity of SOD , POD ,CAT of nectarine during storage period ,and which reached the maximum value at the tenth day after storage with 55.4 U/g ,5.27 U/(g · min) and 26.7 U/g respectively ,then the activity of SOD ,POD ,CAT declined with storage time .The application of calcium fertilizer in soil decreased significantly the membrane permeability and the content of MDA of nectarine during storage pe-riod ,though the membrane permeability and the content of MDA of nectarine increased with stora-ge time ,and reached the maximum value at the 30th day after storage with 60.0% and 6.17 mg/g . Overall ,the application of calcium fertilizer in soil increased significantly the activity of SOD , POD ,CA T of nectarine ,and decreased significantly the membrane permeability and the content of MDA of nectarine during storage period .
