야외 포장에서 십자무늬긴노린재의 연중 발생소장 및 월동, 식이 선호성 등을 조사하여 얻은 결과는 다음과 같다. 시기별 발생소장은 5월 상, 중순에 월동성충이 출현하여 6월 하순부터 8월 중순까지 1세대성충이 출현하고 9월 중순에서 10월 상순에 2세대성충이 출현하였다. 이 2세대성충이 토양 속이나 낙엽밑에서 월동하였다. 십자무늬긴노린재는 백열등(100W), 청광등(BL:20W), 흑광등(BLB:20W)의 유아등에는 모두 유인되지 않았다. 식이 선호성은 박주가리과의 박주가리와 백하수오(큰조롱)에 기주특이성을 보였다.
Background:The study aimed to obtain data on the effects of cultivation and soil reduction of green manure crop on the quantity and quality of organically cultivated Cynanchum wilfordii Hemsley.Methods and Results:The experiment comprised four treatments: control, hairy vetch, barley, and hairy vetch + barley (3 : 2). The plant height in the hairy vetch treatment (86.3㎝) was significantly different from that in the other treatments, whereas the stem diameter leaf area, and special product analysis division (SPAD) value did not differ across the treatments. The largest soil reduction of green manure crop was recorded in the barley treatment (440 ㎏/10 a), whereas the smallest was recorded in the single treatment with hairy vetch (80 ㎏/10 a). The hairy vetch + barley (60 : 40) treatment showed 63% more soil microorganisms than control. Radical scavenging activity estimation revealed that the total polyphenol content was highest (1,740 ㎎/㎏), and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) was 92.6% in the barley treatment. The 2,2’-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) activation was highest in the control (51.1%), and the root yield was the highest in the barley treatment (310 ㎏/10 a).Conclusions:The root yield, total polyphenol content, and antioxidant activity of Cynanchum wilfordii (Maxim.) Hemsley increased in presence of the green manure crop barley.
