“…CMV 내성 GM 고추를 건조된 상태로 유통할 때에 고추 열매에서 분리된 종자가 자연 상태에서 발아하여 환경을 오염시킬 수도 있으므로 건열 처리로 GM 고추의 발아능이 불활성화가 되도록 처리를 해야 한다. (Cho et al, 2009) (Vos et al, 1995;Kim et al, 1999;Bangarwa et al, 2009;Won et al, 2012). 잡초의 생육이 왕성한 시기는 7 -8월로 우점종인 개피의 초장이 1m 정도 자랐다.…”

The effects of wintering conditions and drying methods on the germination rate of CMV-resistant peppers 'H-15', non-GM parental line 'P-2377' and commercial varieties were investigated. In the first year (2012), 'H-15' and 'P-2377' were overwintered for 4 months on the ground (1m height) and underground (10, 20, 30cm depth). Overwintered pepper fruits sown with black PE mulching in early April, both varieties germinated regardless of wintering treatment method. 'H-15' was grown and fruited in all treatments, but 'P-2377' was only fruited in overwintering treatments 20 to 30 cm underground. In the second year (2013) three varieties 'H-15', 'P-2377' and 'Buja' were treated in the overwintering as in 2012, and then sown without mulching. Germinated was achieved, but the weed density (152.6 plants/m 2 , Beckmacia syzigachne 94.6%) was high, so the seedling growth was very poor and no fruiting. The effect of drying methods (2 weeks of sun drying; dry-heat treatments at 50, 60, 70°C during 48 hours) on the germination rate of 4 varieties ('H-15', 'P-2377', 'Shingang' and 'Manita') was investigated in 2013. In the case of seeding immediately after drying treatment, all four varieties germinated in 50°C drying treatment, 'H-15' and 'Shingang' did not germinated at 60°C, and all varieties did not germinated in 70°C treatment. After drying treatment, it was stored at room temperature for 1 year, and a germination test (2014) was conducted. As a result, germination rated was low, but the trend was similar to that in 2013. Even if the color of dried peppers gets worse, it is believed that drying at 70°C before distribution can completely eliminate the germination rate of GM seeds and prevent environmental pollution.

ABSTRACT. Timely application and the choice of herbicides are crucial for red pepper production since the yield is significantly reduced by weed occurrence. Experiments were conducted to provide efficient weed control methods in red-pepper fields. The results suggest the followings: 1) in the field of prevalent grass weeds, application of pendimethalin EC as pre-emergence herbicide after transplanting followed by tank-mix with pendimethalin and fluazipfop-P-butyl EC as post-emergence at 3-5 leaf stage of Digitalia species gave a good control for 80 days without crop injury, 2) as for grass and other weeds occurrence, sequential application of tank-mix with glufosinate-ammonium SL and pendimethalin at 30 days after transplanting (DAT) followed by glufosinate-ammonium. at < 20 cm of weed height with 30 days' interval provided better weed control than 2-time application of glufosinate-ammonium. single application for 80 days in this trial. 3) To prevent from drifting of non-selective herbicide spray mist into red-pepper at furrow application, glufosinate-ammonium. should be applied at 15 cm of spray nozzle height at 20 DAT (18 cm tall of red pepper), and the spray nozzle should be placed below 30 cm above ground to keep spray drift minimum to red pepper with > 40 cm plant height at 40 DAT.
