Abstract

This study was conducted to examine the possibility of producing poinsettia with various growing media containing used perlite and rockwool slabs as medium components. Pot plants of Euphorbia pulcherrima 'Freedom Red' were grown in 10 media containing used perlite and particles of rockwool slabs at various ratios including 1:1 and 1:3 (v/v). Medium containing used perlite and peatmoss at 1:3 (v/v) was employed as the control treatment. Height, root length, length of the longest branch, number of roots, leaf area, and width and length of the largest bract of plants grown in media containing used perlite were significantly greater than those in the control. Stem diameter and bract count were not affected by the medium composition. From the results, used perlite and rockwool slabs were proved to be a practically useful materials as medium components for pot production of poinsettia plants.

본 연구는 배지 구성물질로서 폐펄라이트와 폐암면 입자를 함유한 다양한 생육배지에서 포인세티아의 생산 가능성을 구명하기 위하여 수행되었다. 두 가지 폐배지를 위주로 1:1과 1:3을 포함한 다양한 부피비로 혼합한 10가지 조합으로 실험하였으며, 25% 폐펄라이트:75% 피트모스의 혼합배지를 대조구로 하였다. 초장, 근장, 최대 가지 길이, 뿌리수, 엽면적, 포엽장과 포엽폭은 폐펄라이트를 함유한 배지에서 대조구에 비해 큰 유의차를 보였다. 하지만 경경과 포엽수는 차이가 없었다. 본 결과로 폐펄라이트와 폐배지의 포인세티아 식물의 재배 시 재활용의 가능성이 입증되었다.
