为明确微量元素铁锌硒配施对番茄生长、果实品质的影响，以"普罗旺斯"番茄为试验材料，在氮磷钾供应充分的情况下，采用基施(R)与叶面喷施(L)相结合的方式，设置CK、Zn(L)、Fe(L)、Zn(R)、Zn(R)+Fe(L)、Se(R)、Se(R)+Zn(L)、Se(R)+Fe(L)8 个不同施肥处理，旨在探究铁锌硒配施对番茄生长、果实抗氧化能力及糖代谢的调控作用。结果表明，1)与CK相比，Zn(R)处理的茎粗显著增加 11。24%，Zn(R)+Fe(L)处理植株节间长显著增加 30。13%;2)Zn(R)+Fe(L)处理叶绿素a和叶绿素b分别显著增加26。13%和 41。03%，Fe(L)、Zn(R)+Fe(L)、Se(R)+Zn(L)处理叶片净光合速率分别显著上升了50。28%、70。92%、29。81%;3)铁锌硒单施及配施均能够增加果实中活性物质的含量，其中Se(R)+Zn(L)处理果实中番茄红素、维生素C分别显著上升了 1。04、1。15 倍，总酚、类黄酮含量分别显著上升了 39。19%、37。84%，Se(R)+Zn(L)、Se(R)+Fe(L)处理均能够显著增加果实中抗氧化酶活性，增强果实抗氧化能力;4)除Se(R)处理外，铁锌硒单施及配施均能显著提高番茄果实中还原糖和蔗糖含量。铁锌硒单施及配施能够调控糖代谢相关酶活性，其中Zn(L)处理番茄果实蔗糖合成酶活性显著增加了 79。67%，Zn(L)和Zn(R)+Fe(L)处理下番茄果实蔗糖磷酸合成酶活性分别显著增加了 1。09 和 1。17 倍。
Effects of iron,zinc and selenium on growth,fruit antioxidant capacity and sugar metabolism in tomato
In this study,under the condition of sufficient supply of nitrogen,phosphorus and potassium,the combination of basal application(R)and foliar spraying(L)was used to set up eight different fertilization treatments,including CK,Zn(L),Fe(L),Zn(R),Zn(R)+Fe(L),Se(R),Se(R)+Zn(L),Se(R)+Fe(L),to investigate the effects of iron,zinc and selenium combined application on tomato growth,antioxidant capacity and glucose metabolism.The results showed that:1)Compared with CK,stem diameter of Zn(R)treatment was significantly increased by 11.24%,and internode length of Zn(R)+Fe(L)treatment was significantly increased by 30.13%.2)Zn(R)+Fe(L)treatment significantly increased chlorophyll a and chlorophyll b by 26.13%and 41.03%,respectively.Fe(L),Zn(R)+Fe(L),Se(R)+Zn(L)treatments significantly increased net photosynthetic rate by 50.28%,70.92%,29.81%,respectively.3)Single application and combined application of iron,zinc and selenium could increase the content of active substances in fruits.Lycopene and vitamin C in the Se(R)+Zn(L)treatment significantly increased by 1.04 and 1.15 times,respectively,and the content of total phenols and flavonoids significantly increased by 39.19%and 37.84%,respectively.Se(R)+Zn(L)and Se(R)+Fe(L)treatments significantly increased the activities of antioxidant enzymes and enhanced the antioxidant capacity of fruits.4)Except for Se(R)treatment,iron,zinc and selenium application alone and combined application significantly increased reducing sugar and sucrose contents in tomato fruits.iron,zinc and selenium applied alone as well as in combination were able to regulate sugar metabolism related enzyme activities,in which the activity of sucrose synthase in tomato fruits was significantly increased by 79.67%under Zn(L)treatment,and the activity of sucrose phosphate synthase in tomato fruits was significantly increased by 1.09 and 1.17 times under Zn(L)and Zn(R)+Fe(L)treatments,respectively.
