보광이 온실내 온습도와 절화장미의 생육에 미치는 영향

국문 초록 (Abstract)

국내에서 절화장미의 생산에 있어서, 겨울철 부족한 광량과 저온은 생산량을 감소시키고 품질을 저하시킨다. 이에 일몰 후 고압나트륨등을 보광하여 생산량을 증가하고품질을 향상하기 위해 시험을 수행하였다. 절화장미 ‘챠밍블랙’, ‘핑키걸’ 품종을 사용하였으며 400W의 고압나트룸등을 이용해 35µmol•m-2•s-1의 광을 일몰 후 18시부터 4시간, 8시간, 12시간을 보광하였다. 고압나트륨등을 보광 하였을 때 온실내의 온도는 2~4oC가 상승하였고, 습도는 15~20%가 하락하였다. 고압나트륨 보광에 의한 온도의 상승과 습도의 하락은 절화장미 재배에서 노균병 발생을 억제하는 효과가 있었다. 보광시간이 길어질수록 절화장미의 노균병 발생율이 감소하였다. ‘챠밍블랙’은 8시간 이상의 보광처리구에서, ‘핑키걸’은 12시간보광 시 노균병이 100% 억제되었다. 절화장미에서 일몰후 보광시간이 길어질수록 블라인드의 발생률은 감소하였으나 생산량은 8시간 보광을 실시한 처리구에서 가장많았다. 절화장미의 절화장은 보광을 실시하였을 때 길어졌으며, 보광시간별 유의한 차이는 없었다.

In domestic production of cut-flower roses, the lack oflight and low temperature in winter time reduces the productionand deteriorates the product quality. For this reason, 400W ofhigh-pressure sodium were supplemented to ‘Charming Black’and ‘Pinky Girl’ of cut-flower roses for 4 hours, 8 hours and 12hours each after sunset. During supplemental lighting, thelighting intensity was about 35µmol•m-2•s-1. When high-pressure sodium was supplemented, the temperature inside ofgreen house went up by 2~4 and humidity went down by15~20%. The temperature rise and humidity drop causedby supplemental lighting of high-pressure sodium had aneffect of suppressing downy mildew. The longer of timesupplemental lighting, lowered the occurrence rate of downymildew. The downy mildew in ‘Charming Black’ and ‘PinkyGirl’ was suppressed one hundred percent after staying insupplemental lighting treatment plot for more than 8 hours and12 hours respectively. In cut-flower roses, longer supplementallighting time after sunset, resulted higher flower production.The length of cut-flower got longer when the supplementallighting was executed and there was significant difference bythe time of supplemental lighting
