실험실에서 실시한 검정으로 Lotus와 Red clover 종자의 포장출현율 예측에 효과적인 검정방법을 구명하기 위하여 상이한 조건에서 재배된 종자를 퇴화조절검정법, 인위노화검정법과 전기전도도 검정방법으로 검정하였다. 이들을 포장출현율과의 관련성을 구명 하였던 바 1. Lotus와 Red clover의 포장출현율을 예측할 때 퇴화조절검정에서는 (equation omitted)=12.786＋0.65X(R2 =0.687), 인위노화검정에서는 (equation omitted)=25.989＋0.39X(R2 =0.260), 전기전도도검정에서는 (equation omitted)=141.932-0.86X(R2 =0.238)으로써 예측할 수 있었으며 2. 이들 세가지 검정에서의 결과와 포장출현율과는 다음과 같은 다중회귀방정식으로 나타낼수 있었다. (equation omitted)=-198.16＋2.3493X1 -1.5564X2 ＋1.981X3 (R2 =0.916) 여기서, X1 , 퇴화조절검정법 ; X2 , 인위노화검정법 ; X3 , 전기전도도검정임. 3. 이러한 결과는 단일검정법으로 실내에서 포장출현율을 예측하려면 인위노화검정법이나 전기전도검정법 보다도 퇴화조절검정법이 비교적 효율이 높았으며, 이들 세가지 방법을 병용할 때에는 단일검정법보다도 효율을 증가시킬수 있었다.
The purpose of this study was to compare the test methods for predicting field emergence of Lotus corniculatus and Trifolium pratense. Four seed lots of two herbage legumes were controlled deteriorated, accelerated aged before germination test and conductivity of each seed lot was determined. Those germination percent and conductivity of seed lots were compared with actual field emergence rate. Field emergence rate could be estimated by the controlled deterioration test (R2 =0.687), by the accelerated aging test (R2 =0.260), and by the conductivity test (R2 =0.238). A multiple regression equation for predicting field emergence rate(equation omitted) was estimated as (equation omitted)=-198.16 ＋ 2.3493X1 -1.5564X2 ＋ 1.9812X3 where X1 , percent germination of controlled deterioration test ; X2 , percent germination of accelerated aging test; and X3 , conductivity of solute leakage in the conductivity test. Conclusively, unless multiple tests are not available, the controlled deterioration test was comparatively high efficient for predicting field emergence rate, however, the combined measurements of those three tests can enhance the efficiency.
