Abstract

This study was conducted to investigate the growth characteristics of the shoot and roots and to analyse the morphological characteristics of roots of waterlogging resistant and susceptible maize inbred lines. Six maize inbred lines were treated with waterlogging for 10 days at V3, and the degree of leaf senescence was evaluated for waterlogging resistance. As a result of waterlogging resistance evaluation, KS85 was the most damaged inbred line with 3.33 senescence leaves and 5.54 degree, and KS141 was the least damaged inbred line with 1.33 senescence leaves and 3 degree. At 20 days after treatment, the effect of waterlogging stress on the shoot dry matter accumulation of KS85 and KS141 were decreased by 86.1% and 77.0%, respectively, compared to the control. Similarly, root dry matter accumulation of KS85 and KS141 were decreased by 77.6% and 65.0%. As a result of SEM photographs of the nodal roots of the two maize inbred lines, the thickness of cortex of KS141 was thicker than that of KS85, and the distortion of the cortex was observed in KS85 at 20 days after waterlogging. It was concluded that the thickness of cortex was related to maize waterlogging resistance.

본 연구는 옥수수 습해 저항성 계통과 감수성 계통의 지상부와 지하부 제형질과 뿌리의 형태적 특성을 알아보고자 수행되었다. 6개의 국내 자식 계통을 유묘기(V3)에 10일간 담수처리 한 후 엽노화 정도로 내습성을 평가 한 결과 KS85은 황화엽수 3.33개, 노화정도 5.54로 가장 피해가 커 습해 감수성을 보였으며, KS141은 황화엽수 1.33개, 노화정도 3으로 가장 피해가 적어 습해 저항성을 보였다. KS85와 KS141을 담수 처리 후 20일에 조사한 결과 KS85와 K141의 지상부 건물중은 무처리구 대비 각각 86.1%, 77.0%가 감소되었고, 지하부 건물중은 KS85와 K141이 무처리구 대비 각각 77.6%, 65.0% 감소하여 습해 저항성인 KS141이 감수성인 KS85에 비해 건물중 감소량이 적었다. 두 계통의 지하부 nodal root의 SEM 촬영 결과 피층의 두께가 KS141이 KS85보다 더 현저히 두꺼웠으며 담수 처리 후 KS85는 KS141에 비해 피층의 뒤틀림이 심하여 피층의 두께가 내습성과 관련이 있는 것으로 사료되어진다.
