Abstract
The aim of this research was carried out that leafty and tonic vegetable using garlic (Allium victorialis L. var. platyphyllum Makino) makes use of landscape ground-cover plant. Following shading level treatments (30%, 50%, 80%), garlic was cultivated to investigate plant growth characteristic and chlorophyll content. Leaf number of all treatments was unaffected, and 80% shading treatment had grown vigorous growth 16.8 cm leaf length and 10.1 cm leaf width compared to 13.4 cm leaf length and 7.3 cm leaf width for the non-shading treatment. Fresh weight of non-shading treatment was better than those of three shading treatments, however, 80% shading treatment had produced 10.4 g fresh weight of stem part compared to 8.5 g for the for the non-shading treatment. The chlorophyll content of the 50 and 80 shading treatments showed 42.8% and 40.5% respectively. These treatments increased 36.7% chlorophyll content compared to non-shading treatments. Following shading level treatments, growth characteristics of garlic in 80 shading level treatment shows outstanding growth and it is worthy of planting as shading ground-cover plants.
본 연구는 쌈채 및 강장제로 이용되고 있는 산마늘을 조경용 지피식물로 활용하고자 수행하였다. 차광 정도를 30%, 50%, 80%로 처리하여 생육 특성 및 엽록소 함량 등을 조사하였다. 엽수는 처리구별로 유의성이 인정되지 않았으나 엽장과 엽폭은 80% 차광 처리구가 각각 16.8cm, 10.1cm로 무처리구의 13.4cm, 7.3cm에 비해 우수하였다. 생체중은 무처리구가 차광 처리구에 비해 우수한 것으로 나타났으나 지상부 생체중은 무처기구가 8.5g인데 비해 80% 차광 처리구가 0.4g로 양호하였다. 엽록소 함량은 50% 차광 처리구가 42.8, 80% 차광 처리구가 40.5로 무처리의 36.7에 비해 높았다. 따라서 차광 수준에 따른 산마늘의 생육 특성은 80% 차광 처리구에서 가장 우수하여 음지성 지피식물로서 가치가 있는 것으로 나타났다.
