Abstract

These studies were carried out to ascertain the effects of paraffin oil on prolongation of the green leaf color period in Zoysiagrass. Fifty-fold diluted 98% paraffin oil treatment obtained the lowest reduction rate of green color. In early October we sprayed 50-fold, 100-fold and 200-fold diluted 98% paraffin oil in a Zoysia japonica field in Hapcheon of Gyeongnam and Sangju of Gyeongbuk and in a Z. matrella field in Gumjung of Busan and Anseong of Gyeonggii. Leaf color maintained for 60 days after treatment in Zoysia japonica. Leaf color remained for 60 days after treatment in Anseong, Hapcheon and Sangju when treated in the mid-October. Chlorophyll content was higher in paraffin oil treatment areas than in control areas in early October. Weight reduction rate was lower in the paraffin oil treated than in untreated leaves of Zoysiagrass when sprayed in Gumjung and Anseong in early October and mid-October, respectively. The chlorophyll content in leaves of Z. japonica was increased by increasing the spray volume of paraffin oil in the same dose treated in Lexington, Kentucky, USA. Paraffin oil can be used to prolongate of Zoysiagrass leaf color.

본 연구는 파라핀 오일 처리가 한국잔디의 녹색기간연장에 미치는 영향을 알아보기 위하여 수행하였다. 10월 초순에 파라핀 오일(순도 98%)을 50배와 100배, 200배로 희석하여 경남 합천과 경북 상주지역의 광엽형 한국잔디(Zoysia japonica)와 부산 금정 및 경기도 안성의 중엽형 한국잔디(Zoysia matrella)에 처리한 결과 50배액 처리시 엽색 감소 효과가 높았다. 광엽형 한국잔디에서는 처리 후 60일 후에까지 엽색도가 무처리에 비하여 높게 유지되었다. 파라핀 오일10월 중순 처리 시에도 경기 안성과 경남 합천, 경북 상주 지역의 엽색도가 60일째까지 높게 나타났다. 파라핀 오일 10월 초순 처리 시 엽록소 함량은 무처리에 비하여 높았다. 파라핀 오일 처리 후 절단한 잔디의 지상부 무게 감소율은 10월 초순 부산 금정처리와 10월 중순 경기 안성지역 파라핀 오일 처리에서 낮았다. 미국 켄터키주 렉싱턴의 들잔디에서 동일 농도의 파라핀 오일 처리시, 처리 물량이 많아질수록 엽록소 함량이 높게 유지 되었다. 따라서 파라핀 오일은 가을철 들잔디의 녹색기간 연장에 이용할 수 있을 것으로 생각된다.
