정화 처리토가 렌틸(콩과식물)의 지상부 및 뿌리 성장에 주는영향에 대한 정량평가 (Quantifying Inhibitory Effects of Reclaimed Soils on the Shoot and Root Growth of Legume plant Lentil(Lens culinaris))

초록

A series of pot experiments were conducted to quantitatively estimate inhibitory effects of reclaimed soil on the growth ofLentil (Lens culinaris) with two soils remediated by land farming (DDC) and low temperature thermal desorption(YJ),respectively. After cultivation in a growth chamber for 8 days, plants were harvested for the analysis of 8 indices includingchlorophyll-a and carotenoid in leaves, shoot fresh weight, root dry weight, root length, number of later roots, specific rootlength (SRL) as well as germination rate in comparison to control experiment conducted on nursery soil. Root length wasestimated by SmartRoot program from the digital images of the roots. The results showed germination rate on YJ andDDC soil decreased 29 and 71%, respectively. In comparison to the control, the averaged value of the 8 indices for YJ andDDC soil showed overall growth inhibition was 48 and 68%, respectively. When the same experiment was conducted with25% (W/W) vermiculate amended soil, plant growth on each soil was comparable to that of the control. The resultsimplies reclaimed soils requires additional processes and/or amendments to reuse for plant growth.
