施硒对红芸豆产量及硒运转的影响
Effects of selenium application on the yield and selenium transport of red kidney beans
摘要
Abstract
[Objective]Current study was designed to explore selenium transport way in various organs of red kidney bean plants and the effect of selenium on POD (peroxidase)activity,MDA (malondialdehyde)and GSH (reduced glutathione)con-tent,and yield of red kidney beans,and in order to provide a theoretical basis for selenium-rich red kidney bean production. [Methods]The"British red kidney beans" was used as the experimental material,and the two-factor splitting design was a-dopted.The main factor was set up with soaking treatments with selenium concentrations at five different levels,SS0 (0 mg· L-1 ),SS7.5 (7.5 mg·L-1 ),SS15 (15 mg·L-1 ),SS22.5 (22.5 mg·L-1 ),SS30 (30 mg·L-1 ),while the second factor was set up with foliar spray treatment with selenium concentrations at four different levels,FS0 (0 g·hm-2 ),FS15 (15 g·hm-2 ),FS30 (30 g·hm-2 ),and FS45 (45 g·hm-2 ).Tap water served as the control,and a total of 20 treatment combinations were in-volved.[Results]Compared with control group,selenium application could effectively increase the POD activity,GSH con-tent,and MDA content of red kidney beans.The selenium content in different organs of red kidney bean plants was various as grain>leaf>pod>stem,and it was increased by 2.5~1 3.2,4.7~23.0,0.1~31.6,and 0.26~1 5.9 times,respectively, compared with control group,and the highest yield was increased by 0.9 times.[Conclusion]The study indicated that bean seeds treated with soaking method at selenium concentration of 1 5~22.5 mg·L-1 coupled with foliar spraying method at sele-nium concentration of 30~45 g·hm-2 provide good bean production.关键词
